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 ...

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 ...

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.

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 ...

Theories of evolution were developed without an understanding of genetics, and while our ability to study genes has advanced tremendously, those advancements have happened only in the past few decades ...

Researchers in Alberta uncovered a fossil fish that rewrites the evolutionary history of otophysans, which today dominate freshwater ecosystems. The new species, Acronichthys maccognoi, shows early ...

Earth, rocks, evolution, and fish : background information to understanding fish evolution -- Glorified swimming worms : the first fishes : origins of chordates and the first vertebrates -- Jawless ...

Why do you think giraffes have such long necks? It’s a question that has perplexed scientists for years. Do you think giraffes have long necks to reach food in high places? Maybe you are onto ...

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 ...
