Synchrotron imaging of complete fossil fish skeletons from Alberta's Pisces Point site has revealed new evidence about ...

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.

Taking your mouth to your plate might not be accepted practice at the human dinner table, but in the fish world it is a winner. The ability, known as protrusion, allows fish to extend their jaw and ...

Some fish come onto the land to hunt or move around. Typically, this behavior happens at nighttime, as seen in eels, for instance. In the new study, researchers have found that such amphibious fishes ...

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 ...

Paleontologists at University College Cork have discovered that the evolution of fish is linked to the shape, location and abundance of tiny melanin-rich granules called melanosomes. These features ...

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 ...

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 ...

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 ...

Approximately 4 billion years have passed since life first emerged on Earth.Over a long period, life has changed its form, adapted to its environment, and continued to evolve.Life that originated in ...

A beautifully preserved fossil of an ancient fish shows the evolution of the bones in our hands started before animals emerged onto land. Palaeontologists have discovered the almost complete skeleton ...
