Why are there so many species of coral reef fish? According to a new study, it’s because about 50 million years ago, some ...

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 ...

A new study in Proceedings of the Royal Society B reveals the surprising neurological landscape of fish brains. Harvard ...

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 ...

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 ...

A fossil fish skull, Macropoma gombessae, that sat unnoticed in a London museum for nearly 140 years has now changed fish ...

A new study shows that fish brains often do not fill their skulls. This changes how scientists study brain evolution and ...
