The discovery of a golden scaleless fish in China is helping scientists understand how animals evolved to live in caves.

Evolution has created some pretty crazy things, and the head of this fish is definitely one of them. The rockhead poacher (Bothragonus swanii) is small, armored, and shaped remarkably like a stone.

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 ...

Primeval fish that were thought to be "living fossils," largely unchanged since the time of the dinosaurs, are actually evolving dramatically — and they evolved faster when Earth's continents moved ...

When we say that someone is a “fish out of water,” we sometimes mean to suggest that they are uncomfortable or out of their ...

Fish evolution is so strange that it's given us species that can count, change color by "seeing" with its skin and even fish that can "sing." But sea robins in the family Triglidae are some of the ...

Fossils over 300 million years old reveal the evolution of a tongue bite in an ancient group of deep-bodied ray-finned fishes, such as Platysomus parvulus. Experts have uncovered the earliest known ...

While the sea robin has legs, it still doesn’t need a bicycle. By Sofia Quaglia The sea robin has fascinated scientists for decades. It has the body of a fish, the wings of a bird and the legs of a ...

It's not what you do, it's how readily you do it. Rapid evolutionary change might have more to do with how easily a key innovation can be gained or lost rather than with the innovation itself, ...

Researchers have traced cell origins critical to vertebrate evolution by studying a group of primitive, bloodsucking fish called lampreys. When you purchase through links on our site, we may earn an ...
