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 ...

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 June 24 th in the open-access journal PLOS ...

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 exhibit considerable biodiversity in genetics, morphology and behaviour that has been shaped by environmental factors such as habitat variation, climate fluctuations, and geological events. By ...

The deep sea, covering approximately 65% of Earth's surface, has long been considered a biological desert. In this extreme environment—particularly in the hadal zone at depths greater than 6,000 ...

A bottom-dwelling, mud-grubbing, armored fish that swam in tropical seas 423 million years ago is fundamentally changing the understanding of the evolution of an indisputably indispensable anatomical ...

Whole skeleton of Dipterus, an extinct lungfish from the middle Devonian period. Specimen (UMMP 16140) from the University of Michigan Museum of Paleontology. ANN ARBOR—If you're reading this sentence ...

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 ...

Complex teeth with multiple cusps in an African cichlid fish. 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 ...

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 ...
