Paleontologists at University College Cork have discovered that the evolution of fish is linked to the shape, location and ...

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.

New research links melanosome shape and abundance in fish eyes and organs to vision and terrestrial adaptation, with patterns ...

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 ...

The first cytogenetic study of three Atlantic flying fish species reveals striking chromosomal and ribosomal DNA divergence ...

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 ...

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. Evolution doesn’t ...

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 ...

Fossils in Brazil indicate a more complex evolutionary history for ray-finned fish brains than previously anticipated, according to new research. The researchers not only found well-preserved brains ...

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 ...
