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 ...

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

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 ...

An ancient, well-preserved fish brain analyzed recently by University of Michigan scientists could unlock new discoveries about evolution and the formation of fossils. The brain, which the university ...

The cichlid fish of Africa's Great Lakes have formed new species more rapidly than any other group of vertebrates. A new study shows that the ease with which these fish can develop a biological ...

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 ...
