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 ...

Butterfly fish feeding on a coral reef. The ability to bite food off hard surfaces, such as coral, evolved about 50 million years ago and led to the rapid formation of new species of fish on coral ...

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 ...

If you're reading this sentence, you might have a fish to thank. Fish were the first animals to evolve jaws. They use their jaws primarily to eat, but also for defense, as tools—such as to burrow or ...

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 ...

The deep ocean remains largely unexplored, despite containing a large portion of the living organisms and animals on Earth.

A trade-off between tooth size and jaw mobility has restricted fish evolution, Nick Peoples at the University of California Davis, US, and colleagues report June 24 th in the open-access journal PLOS ...

A new study has rewritten a key chapter in the story of vertebrate evolution. Researchers from the University of São Paulo (USP) in Brazil and the Smithsonian Institution in the United States have ...

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 ...

When you think about human evolution, there’s a good chance you’re imagining chimpanzees exploring ancient forests or early humans daubing woolly mammoths on to cave walls. But we humans, along with ...

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 ...
