Why does a Caribbean angelfish sometimes resemble its Indo-Pacific cousin, even though they have never lived in the same ocean? Why do coral reefs harbor such a wide range of stripes, spots and ...

A research team led by Profs. Zhu Min, Lu Jing, and Zhu You'an from the Institute of Vertebrate Paleontology and ...

Reef fish in different oceans often develop similar color patterns because evolution explores the same set of biological possibilities.

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 ...

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 ...

In Lake Malawi, hundreds of species of cichlid fish have evolved with astonishing speed, offering scientists a rare opportunity to study how biodiversity arises.

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 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 ...

While there is a common belief that the evolution of humans can be traced back to fishlike vertebrate ancestors, pinpointing the origins of bony fish — a key group in this evolution — remains ...

Chinese paleontologists have discovered the world's oldest complete bony fish fossils, dating back 436 million years ...
