During these waves of mass extinction, most vertebrate survivors were confined to refugia, or isolated biodiversity hotspots ...

Reef fish evolved the ability to feed by biting prey from surfaces relatively recently, a UC Davis study shows. The innovation has driven an explosion of evolution in reef fish. Image shows a rainbow ...

Along the murky bottom of the Amazon River, serpentine fish called electric eels scour the gloom for unwary frogs or other small prey. When one swims by, the fish unleash two 600-volt pulses of ...

A new study of the freshwater greenfin darter fish suggests river erosion can be a driver of biodiversity in tectonically inactive regions. New findings could explain biodiversity hotspots in ...

A study published in the Nature journal alters how the evolution of fish has been historically understood. Fossilized fish and other sea creatures have often been pivotal in new scientific discoveries ...

You may have come across a meme showing an ancient fish known as Tiktaalik. It shows the green, eel-like creature crawling out of the sea about 375 million years ago — about the time that scientists ...

Fish may be evolving to swim faster and evade capture in trawler nets, according to research. Scientists at the University of Glasgow found that fitter fish are better at evading nets and believe that ...

Fish evolution is so strange that it's given us species that can count, change color by "seeing" with its skin and even fish that can "sing." But sea robins in the family Triglidae are some of the ...
