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 ...

Evolution is driven by changes in DNA that sometimes promote adaptation, altering traits like disease resistance or ...

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 ...

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 ...

A series of experiments that included stickleback fish hookups, CRISPR, and lake hopping has confirmed a long-standing, yet unproven, assumption about natural evolution. It also debunks a talking ...

Research shows that coral reefs’ diversity of fish results from a relatively recent innovation among bony fish: biting prey from surfaces. Although jawed fish appear in the fossil record almost 500 ...

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 ...

Coral reefs are home to a spectacular variety of fish. A new study shows that much of this diversity is driven by a relatively recent innovation among bony fish -- feeding by biting prey from surfaces ...

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 ...

Coral reefs are home to a spectacular variety of fish. A new study by biologists at the University of California, Davis, shows that much of this diversity is driven by a relatively recent innovation ...
