What if scientists discovered a new animal without first finding it alive in a forest? Something close to that happened with a mysterious pangolin. The first major clues came from scales seized from the illegal wildlife trade in Hong Kong. DNA from some of those scales did not match known Asian pangolin species. Years of further genetic work eventually provided strong evidence for a separate species, now proposed as Manis mysteria. Researchers found that its lineage separated from its closest known relatives more than 5 million years ago. The discovery shows how DNA taken from trafficked wildlife can reveal animals that science still knows very little about.

Seized pangolin scales revealed the first clues

The story began years before scientists had enough evidence to propose a new species. Researchers studied 239 pangolin scale samples from two confiscations in Hong Kong. DNA testing revealed 13 different genetic forms known as haplotypes. Some belonged to the known Sunda pangolin, but another genetic group created a puzzle. Its DNA did not match sequences from any known Asian pangolin species.

Researchers published those results in 2015. At the time, they described the unknown group as a possible hidden pangolin lineage rather than immediately declaring a new species. That was an important difference. Finding unusual DNA does not automatically prove that a separate species exists. Scientists needed much more evidence before reaching that conclusion. Still, the strange genetic results gave researchers a reason to keep investigating.

More mystery pangolin DNA appeared in China

The Hong Kong samples were not the end of the story. Researchers later identified two more unusual mitochondrial DNA types in separate confiscations from Yunnan, China. These genetic sequences lined up with the mysterious pangolin DNA previously detected in the Hong Kong material. Finding related DNA in separate seizures made it harder to explain the original discovery as one strange or isolated sample.

Scientists still needed stronger evidence. Mitochondrial DNA can provide important clues about relationships between animals, but researchers wanted to examine much more of the genome. They also needed to compare the mystery samples directly with all eight pangolin species already recognized at the time. This would help determine whether the unusual DNA represented variation within a known species or something truly different.

DNA points to a separate pangolin species

The results provided what researchers called strong genomic evidence for a separate species. The mystery samples formed a lineage distinct from the eight pangolin species already known to science. Researchers proposed the scientific name Manis mysteria for the animal. If formally accepted across pangolin taxonomy, it would represent a ninth living pangolin species and a fifth species within the Asian genus Manis.

Scientists did more than compare DNA. They also examined the physical features of the scales. Those measurements showed that the mystery pangolin belonged with Asian pangolins rather than the African species. The genetic evidence then allowed researchers to look much deeper into where the animal fits within the pangolin family.

Its lineage separated over 5 million years ago

Genomic analysis showed that Manis mysteria is not simply a very recent branch of another known pangolin species. Researchers concluded that the lineage separated from the ancestors of the Philippine pangolin and Sunda pangolin more than 5 million years ago. That means its independent evolutionary history reaches millions of years into the past.

The number needs to be described carefully. Researchers did not show that one individual pangolin suddenly became a new species exactly 5 million years ago. Species develop through long evolutionary processes. Genetic studies allow scientists to estimate when different lineages shared common ancestors and began separating. In this case, the genomic evidence points to a split more than 5 million years in the past.

Scientists still have major questions to answer

Finding strong genetic evidence for a species is not the same as knowing everything about the animal. Researchers still need to determine where Manis mysteria lives in the wild. Its natural geographic range remains uncertain because much of the material used for the research came through illegal wildlife trade. A confiscated scale can reveal the animal’s DNA, but it does not automatically reveal the exact forest where that animal lived.

This creates one of the biggest challenges surrounding the discovery. Scientists want to study living populations, their habitat, numbers, behavior, and threats. Those details are needed to understand how well the species is surviving. Without a clear range, even basic questions about where conservation work should focus become harder to answer.

The illegal wildlife trade helped expose the mystery

There is a troubling twist at the center of the discovery. Illegal wildlife trafficking is a major threat to pangolins, yet confiscated material from that same trade helped scientists detect Manis mysteria. Hong Kong authorities have intercepted very large shipments of pangolin scales over the years. In one 2014 case, customs officers seized about 1,000 kilograms of scales from a container arriving from South Africa.

DNA forensics can turn confiscated wildlife products into scientific evidence. Researchers can extract genetic material from scales and compare it with reference samples from known species. This can help identify which pangolins are appearing in illegal shipments. It can also help researchers study genetic diversity and learn more about where trafficked animals may fit within the pangolin family.

Imagine looking into clear ocean water and seeing bright mahi mahi swimming near enormous humpback whales. Footage described as being captured off Maui shows these very different ocean animals sharing the same stretch of water. The smaller fish move through the blue water while the huge whales swim nearby, creating a striking difference in size and appearance.

The scene does not show that the two species are working together or directly interacting. Instead, it captures a brief moment when mahi mahi and humpback whales happen to be visible in the same area. The footage offers a simple look at how many different animals can move through the waters around Hawaii.

Mahi mahi appear beside huge humpback whales

The first thing that stands out in the footage is the difference in size. Humpback whales are huge marine mammals with broad bodies, while mahi mahi are much smaller fish. Seeing them within the same view makes that difference easy to notice. The whales move through the water with their large bodies clearly visible, while the mahi mahi appear much smaller beside them.

The contrast also comes from the way the animals look. Mahi mahi are known for their bright appearance and streamlined bodies. Humpback whales have a much heavier body shape. When both are visible in clear water, viewers can compare two animals built for very different lives. One is a fast-moving ocean fish, while the other is a massive marine mammal. Their shared appearance in the footage creates the main attraction of the scene.

Clear water makes the ocean encounter easy to see

Clear water plays an important role in the footage. Much of a whale’s body normally remains hidden beneath the surface when people watch from a boat. Underwater footage can provide a very different view because viewers can see more of the animal as it moves. When smaller fish are swimming nearby, the clear water can also make it easier to follow their movements around the much larger whales.

This underwater view changes the sense of scale. From above the surface, a person might see a humpback whale’s back, tail, or blow without seeing its whole body. Looking through clear water gives a better idea of how much space the whale takes up. The mahi mahi provides another point of comparison. Their smaller bodies make the whales appear even larger as both animals move through the same blue surroundings.

Mahi mahi are built for life in open water

Mahi mahi are pelagic fish, meaning they spend much of their lives in open ocean waters rather than staying close to the seafloor. They are highly mobile and can travel across large areas. Their long bodies are shaped for swimming through open water, and scientific research has examined how water temperature affects their swimming ability and where they are likely to occur.

Their appearance is another reason they stand out on camera. Mahi mahi can show bright shades across their bodies, making them easy to notice when the water is clear enough. That creates a big visual difference beside the darker and much larger humpback whales. In the Maui footage as described, the fish adds quick movement and flashes of color while the whales provide the size and scale that dominate the underwater scene.

Humpback whales spend time around Hawaii

Humpback whales are a familiar seasonal presence in Hawaiian waters. They travel to Hawaii during part of their yearly cycle, and whale watching around the islands gives people opportunities to see them at the surface. Reports from Hawaii in 2026 continued to document humpback mothers and calves in island waters as the whales approached the end of their seasonal stay.

Maui is especially well known for views of humpback whales during their time around Hawaii. The animals can be seen traveling, resting, and showing different behaviors at the surface. Underwater footage offers another perspective because it can reveal much more of their bodies. Instead of seeing only the part of a whale that rises above the water, viewers can watch the animal move through the ocean itself.

Two very different animals share one ocean scene

Putting a mahi mahi beside a humpback whale creates an unusual comparison. Both animals live in the ocean, but they are very different. Mahi mahi are fish, while humpbacks are mammals. Their bodies also move through the water differently. The smaller fish can appear quick and agile, while the whale’s huge body creates slower-looking movements across the camera view.

That difference is what makes the footage interesting without needing a dramatic event. The whales do not have to breach, and the mahi mahi do not have to chase anything. Simply seeing both animals within one underwater view creates enough visual interest. Their different sizes, shapes, and movements make it clear that the open ocean can support animals with very different ways of living.

The footage captures a brief shared moment

The strongest part of the footage is its simplicity. Mahi mahi are visible in the water near humpback whales, giving viewers a clear look at two very different kinds of marine life at the same time. There is no need to claim that the animals are friends, traveling together, or helping one another. The available description does not establish any of those behaviors.

Instead, the moment can be appreciated for what is visible. Bright, fast-moving fish pass through the same clear water occupied by enormous whales. Their difference in size becomes clear immediately. The blue ocean provides a simple background, while the animals create all the movement in the scene.

Imagine heading onto the ocean to hunt a whale and having a group of wild orcas helping you find it. For generations, something close to this happened around Twofold Bay near Eden, Australia. Local whalers and wild killer whales became part of an unusual hunting relationship. The orcas found passing baleen whales, helped move them toward the coast, and alerted people when whales were nearby.

The most famous member of the group was an orca called Old Tom. The story of the Eden killer whales shows how wild animals and humans once worked toward the same goal without the orcas being trained or kept by people.

Wild orcas helped whalers find passing whales

The waters around Eden were once visited by groups of killer whales that became well known to local whalers. Historical accounts preserved by the Eden Killer Whale Museum describe the orcas working together when baleen whales passed through the area. Some killer whales stayed farther offshore and helped drive passing whales toward the coast. Others joined the attack or positioned themselves where they could stop a whale from getting away. At times, the local group may have included dozens of orcas working across the waters around Twofold Bay.

This gave human whalers an important advantage. Spotting and reaching a large whale from a small shore based boat could be difficult. The orcas were already moving through the water and could find passing whales before people did. Their activity could tell the whalers that an opportunity had appeared offshore. The humans could then launch their boats and join the hunt. The relationship was unusual because the killer whales were wild animals. They were not kept in pens or trained like working animals. They returned to the area and repeatedly took part in hunts.

Orcas could alert people when whales arrived

Finding the target was only part of the orcas’ role. Historical accounts describe some killer whales approaching the whaling station when another whale was nearby. Old Tom became especially famous for this behavior. The Eden Killer Whale Museum says he would swim toward the mouth of the Kiah and slap his tail on the water. Whalers understood this activity as a signal that a whale had been found, allowing them to prepare their boats and head onto the bay.

Once the boats were moving, the killer whales could remain involved. Old Tom was known for swimming beside the whalers during the chase. Accounts even describe him grabbing ropes with his teeth. His preserved skeleton provides an unusual piece of physical evidence connected with those stories. The teeth in his lower jaw show clear wear, which the museum links to his habit of taking ropes in his mouth. This makes Old Tom more than a character from an old tale. His skeleton remains preserved in Eden and can still be studied today.

Old Tom became the most famous killer of Eden

Many killer whales were known to the people around Eden, but Old Tom became the best remembered. The Eden Killer Whale Museum says he measured about 22 feet, or 6.7 meters, long and weighed around six tons. His tall dorsal fin helped people recognize him at sea. Old Tom belonged to one of the groups that worked around the bay, and he became closely linked with the Davidson family, whose shore based whaling operation became an important part of the Eden story.

Old Tom was not the only named orca. Historical records preserved by the museum include animals called Stranger, Hooky, Cooper, Big Ben, Little Jack, and others. The museum has names for 21 recognizable killer whales, although records from the period are incomplete. Reports from the earlier years of Eden whaling suggest that several groups could cooperate during hunts. This matters because the partnership was larger than one famous animal. Old Tom became its symbol, but generations of killer whales appear to have taken part in the unusual relationship.

The Law of the Tongue rewarded the orcas

The partnership worked because both sides could gain food from the same hunt. Historical accounts describe a custom that became known as the Law of the Tongue. After a whale had been killed, the carcass could be left so the killer whales had access to parts they preferred, especially around the mouth and tongue. The human whalers could then recover the carcass and use the remaining parts. This arrangement gave the orcas a reason to remain involved in hunts instead of simply locating prey and disappearing.

The name makes the arrangement sound like a written contract, but it was not one. There was no human-style agreement that the killer whales could understand in words. Instead, repeated behavior appears to have allowed both sides to benefit. The orcas helped locate and control large prey, while the humans brought their own hunting abilities to the chase. Afterward, both could gain food or useful material from the same whale. This repeated pattern became one of the most famous parts of the Eden whaling story.

The partnership lasted across generations

The cooperation around Eden was not a single lucky encounter. Modern scientific research describes cooperative hunting between humans and killer whales in the area as having been reported for almost a century. Historical records also suggest that different groups of orcas took part over time. This long period makes the story especially unusual. Individual humans and individual killer whales came and went, yet the basic pattern continued through generations of whalers and animals.

The relationship also has a deeper Indigenous history. Aboriginal people had long connections with the killer whales and waters of the region before European shore-based whaling expanded there. Later whaling operations included Aboriginal whalers, and the history surrounding Eden’s killer whales cannot be understood only as a story about European settlers. The cooperation eventually became closely connected with the Davidson family’s operation, but the relationship between people, whales, and the waters around Eden reaches further back than Old Tom’s famous years.

Old Tom left behind evidence of the alliance

Old Tom survived into the final years of the story. On September 17, 1930, his body was found floating in Twofold Bay. Local people decided to preserve his skeleton rather than allow this well-known animal to disappear from history. His remains eventually became central to the creation of the Eden Killer Whale Museum. The museum was established to preserve Old Tom’s skeleton and tell the story of the relationship between the killer whales and local whalers.

Scientists are still learning from Old Tom. Researchers later extracted DNA from his remains and compared it with genetic information from killer whales around the world. Their study found that Old Tom was most genetically similar to modern killer whales from New Zealand, although much of the genetic variation in his genome was not shared with the populations used for comparison. Researchers have not established that direct descendants of the Eden killer whales survive today.

A black bear walking into coastal water may seem out of place, but the shoreline can provide an important source of food. A coastal black bear can move between forests, streams, beaches, and shallow water while searching for its next meal. Salmon and other foods linked to the coast can give bears valuable feeding opportunities at different times of the year.

Their flexible diet allows them to use whatever the land and water provide. Scientists studying coastal bears are learning how these marine resources can affect where bears go, what they eat, and how they compete with other animals for food.

Coastal black bears search beyond the forest

Black bears are strongly linked with forests, but coastal animals do not stop searching for food when they reach the shoreline. In places where land meets the ocean, a bear can move between very different habitats during the same day. Forest plants and other foods may be available inland, while fish and marine food sources can appear along streams, beaches, and tidal areas. This gives coastal bears more places to search. Their ability to use many kinds of food helps explain why they can take advantage of both forest and coastal environments.

This flexible behavior becomes especially useful when a food source appears only for a limited time. A bear can travel toward a stream when salmon are available and later search somewhere else as conditions change. It does not need to depend on one type of meal throughout the entire year. Researchers studying coastal British Columbia have found strong links between salmon availability and black bear diets. Their work shows that the timing and variety of salmon can change how much fish bears are able to eat.

Salmon can become an important coastal meal

Salmon are one of the clearest examples of a marine resource that becomes available to bears near the coast. The fish spend much of their lives connected to the ocean before returning to freshwater areas to reproduce. When salmon enter streams and rivers, black bears can gain access to a rich food source. A bear may search shallow water or the edges of a stream for a chance to catch a fish. Images of coastal black bears carrying salmon show just how closely these animals can be linked with seasonal fish movements.

Scientists have found that the number of salmon species available can matter as much as the total amount of fish. Different salmon species can arrive at different times and use different parts of waterways. That can spread feeding chances across a longer period and a larger area. In one major coastal British Columbia study, greater salmon species diversity was linked with much higher salmon consumption by black bears. The research showed that access to several salmon species could give bears far more chances to feed than one large run of a single species.

The shoreline offers more than one food source

Salmon are important, but they are not the only reason a coastal black bear may move toward the ocean. Shorelines can contain many possible foods, especially where tides expose areas that were underwater only hours earlier. Bears are opportunistic feeders, meaning they can use different foods when they become available. This flexibility allows a coastal bear to explore beaches, stream mouths, tidal areas, and nearby forest habitat instead of relying on one feeding location.

Research has also shown that black bears can use marine food connected with Pacific herring. A study from British Columbia documented black bears responding to herring spawning events, providing evidence that bears can take advantage of food moving between ocean and land ecosystems. This is important because it shows that coastal black bears are not simply forest animals that happen to live near water. Their feeding behavior can connect them directly with events taking place in the marine environment.

Rich food can bring bears into the same areas

A strong food source can attract more than one bear to the same general area. Salmon streams are a good example because many fish may become available during a limited period. When several bears want access to the same food, competition can become part of the feeding process. A bear may have to change where it searches or how long it stays in one place, depending on the presence of other animals. Larger or more dominant bears can also affect the choices available to others.

Research from the Great Bear Rainforest has shown a clear example of this competition. Scientists studying black bears and grizzly bears found that black bears ate less salmon in watersheds where grizzly bears were also present. The study estimated that black bears consumed about 40 percent less salmon when the two species shared the same watersheds. That finding shows that access to food is shaped by more than the number of fish. The other bears using the same area can also affect what an individual black bear gets to eat.

Coastal bears adjust as food changes

The coast is not a place where the same meal is available every day. Salmon runs appear during certain periods, tides move in and out, and other food sources change with the season. Coastal black bears need to respond to those changes. Their broad diet gives them an advantage because they can move from one food source to another. When fish become available, they can focus more attention on waterways. When that opportunity changes, they can return to other foods in nearby habitats.

The variety of salmon species can make this changing food calendar even more important. Researchers found that different salmon species can extend the period when fish are available because they do not all arrive in the same place at exactly the same time. Some use different parts of a river or arrive during different periods. This creates a moving series of feeding opportunities for bears. Scientists sometimes study these patterns to understand how seasonal food affects animal movement, diet, and the health of wildlife populations.

Scientists study how the ocean shapes bear life

Researchers can learn about coastal black bear diets without watching every meal a bear eats. One major study used hair collected from bears and analyzed chemical signals inside it. Those signals helped researchers estimate how much salmon had become part of each bear’s diet. The work included hundreds of black bears across a large section of coastal British Columbia. By comparing bear diets with salmon species, salmon amounts, and the presence of competing bears, scientists were able to study how several parts of the ecosystem fit together.

The research shows why the connection between ocean and land matters. Salmon begin as part of a marine food system but later enter rivers where bears can catch them. Herring can also create feeding opportunities that reach animals living on shore. A coastal black bear can therefore be influenced by events happening in both ecosystems. Studying these connections helps scientists understand why certain shorelines and waterways become important feeding areas and why changes in marine food can affect animals living far beyond the water itself.

Imagine looking at an octopus on a rocky seabed and then losing sight of it only seconds later. Octopus camouflage can change color, pattern, brightness, and even skin texture very quickly. Researchers studying these animals have found just how active this system can be. Marine biologist Roger Hanlon has said that octopuses he watched made an average of 177 camouflage decisions during a single hour.

Their skin contains special structures controlled by nerves and muscles, allowing an octopus to change its appearance as the world around it changes. Scientists are still learning how this system works and how the animal combines its eyes, brain, skin, and body to create such effective disguises.

Octopus camouflage can change again and again

An octopus does not always choose one disguise and keep it for a long time. As the animal crawls across sand, rocks, plants, and other surfaces, its surroundings keep changing. Its appearance can change too. Hanlon has described observations in which octopuses made an average of 177 camouflage decisions in one hour. That works out to almost three decisions every minute on average. These decisions can involve changes in the way the animal’s skin looks as it moves through different parts of its environment.

The number is important because it shows how active octopus camouflage can be. It is not simply like putting on one coat and wearing it all day. The animal can keep adjusting its appearance as it travels. Researchers studying cephalopods have found that these animals use changing colors, patterns, and textures for camouflage as well as other types of behavior. Their changing skin can give scientists clues about how the animal sees and responds to the world around it.

Tiny skin organs help an octopus change color

Much of an octopus’s fast color control begins with special structures called chromatophores. These are pigment organs in the skin. Muscles and nerves control them, allowing areas of color to become more or less visible. Large numbers of chromatophores can work together across the body. By controlling these structures in different combinations, an octopus can create spots, darker areas, lighter areas, and other patterns that change the way its body looks against the background.

Chromatophores are only part of the system. Cephalopod skin can also contain structures called iridophores and leucophores, which interact with light in different ways. Together, these parts of the skin help create a wide range of visible effects. Research has shown that octopuses can change both the lightness and color qualities of their bodies. This allows them to match many types of backgrounds better than they could with just one fixed body color.

An octopus can also change its skin texture

Color alone cannot always hide an animal. A smooth octopus sitting beside a rough piece of coral could still be easy to notice because its outline and surface look different. Some octopuses solve this problem by changing the texture of their skin. They use small structures called papillae that can rise from the body or flatten again. These changes can make the skin look rough, uneven, or covered with bumps instead of staying smooth.

Scientists have found that muscles in the skin control these three-dimensional structures. When the papillae rise, they can break up the smooth outline of the octopus and help its body resemble nearby objects. An octopus beside a rough surface can therefore change more than its color. It can also change the shape of its skin. When it needs to move differently, the skin can become smooth again. This ability gives the octopus another tool for hiding in complex underwater environments.

Octopus skin can sense changes in light

One of the strangest discoveries about octopus skin is that it can respond to light even without information coming directly from the eyes. Researchers studying the California two-spot octopus found that isolated skin could react when exposed to light. The skin contains light-sensitive proteins known as opsins, which are related to proteins involved in vision. Researchers saw chromatophores expand when the skin was exposed to light, showing that the skin itself has a basic way to detect changes in brightness.

Calling this ability seeing with the skin can be useful, but it needs an important explanation. Octopus skin does not appear to form detailed pictures of the world in the way the eyes and brain do. Researchers at the University of California, Santa Barbara, explained that the skin can detect changes in light or brightness but does not detect detailed edges and contrast in the same way as normal vision. Scientists are still studying exactly how this skin-based light sensing helps a living octopus control its appearance.

The brain controls a complex, moving display

An octopus has to control many parts of its skin at the same time to produce useful camouflage. The brain and nervous system send signals that help control color, pattern, and texture across the body. This can create a broad matching pattern instead of random patches appearing in different places. Researchers describe cephalopod skin as a fast-changing display system that can react to information the animal receives from its surroundings.

This control can be very fast because the skin structures respond directly to nerve and muscle activity. Thousands of pigment organs can take part in a single display. They can form spots, bands, light areas, dark areas, or mixed patterns. Papillae can also alter the physical surface of the skin. Together, these systems allow an octopus to change several parts of its appearance rather than simply switching from one color to another. Scientists study these changes to understand how the animal turns visual information into a body pattern.

Octopus camouflage is powerful but takes energy

Changing appearance may look effortless, but research shows that the process has a real energy cost. A 2024 study examined the energy needed for rapid color change in octopuses. The researchers found that fully activating the chromatophore system can require a large amount of energy. The cost was close to the amount of energy an octopus uses while resting. This shows that the moving colors across its skin are produced by an active biological system rather than a simple change that happens for free.

Scientists continue to study octopus skin because it combines several unusual abilities in one animal. The skin can change visible color and pattern, alter its physical texture, and even respond to light. Researchers have also used these animals as inspiration when developing materials that can change their appearance or surface. A Stanford research team reported in 2026 that it had developed a flexible material inspired by animals such as octopuses and cuttlefish that could change both color and texture. The natural system remains far more complex, but it continues to give researchers new ideas about adaptive materials and camouflage.
