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.

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 ...

At first glance, tube-eyes and cods seem nothing alike. The former, a ribbon-shaped, deep-sea fish, has bizarre tubular eyes that resemble goggles. The latter, one of the world’s most commercially ...

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 ...

Chinese scientists have discovered fossils of bony fish dating back about 436 million years, providing key evidence that helps fill major gaps in the evolutionary chain linking ancient fish to humans.

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 ...

The mighty tuna is more closely related to the delicate seahorse than to a marlin or sailfish. That is one of the surprises from the first comprehensive family tree, or phylogeny, of the "spiny-rayed ...

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