A new fossil study by scientists challenges long-held ideas of fish evolution, revealing surprising insights into early ...

Learn more about the amblyopsid cavefishes, the eyeless fish that inhabit the caves of eastern North America, whose evolution can uncover the age of difficult-to-date cave systems. This is the Hoosier ...

Why are there so many species of coral reef fish? According to a new study, it’s because about 50 million years ago, some fish figured out how to bite food from hard surfaces. Evolution doesn’t ...

Atlantic and Baltic herring are typical plankton-eating fish of central importance for the northern Atlantic Ocean and Baltic Sea ecosystems. A new study published in Nature Communications led by ...

Some fish come onto the land to hunt or move around. Typically, this behavior happens at nighttime, as seen in eels, for instance. In the new study, researchers have found that such amphibious fishes ...

Scientists have discovered how ancient armoured fish used surprisingly different jaws to hunt and crush prey more than 400 ...

The deep ocean remains largely unexplored, despite containing a large portion of the living organisms and animals on Earth. Among the many creatures populating the deep-sea are so-called Cyclothone, ...

Why do you think giraffes have such long necks? It’s a question that has perplexed scientists for years. Do you think giraffes have long necks to reach food in high places? Maybe you are onto ...
