When you and I take a deep breath, we pull air into our lungs. That’s because humans are mammals. But fish aren’t mammals. They usually don’t breathe air. They usually don’t have lungs. That’s what I ...

Mudskippers break the rules of fish biology by breathing through their skin, walking on their fins and thriving on land where ...

A collaborative team of scientists recently found that there is no physiological evidence supporting a leading theory -- which involves the surface area of fish gills -- as to why many fish species ...

The middle ear of humans evolved from fish gills, according to a study of a 438 million-year-old fossil fish brain. Scientists discovered the fossil of the braincase of a Shuyu fish. Despite its skull ...

Fish can suffocate and die from oxygen deprivation, even when surrounded by water. This occurs when dissolved oxygen levels are too low due to pollution, heat, or other environmental factors, or if ...

The skeletal structure of a fish's gill arches and paired fins are quite similar – enough so that it was once believed the fins evolved from the arches. Although that theory has since been discounted, ...

Humans' outer ears may have evolved from the gills of prehistoric fish, a new study finds. Gene-editing experiments indicate that cartilage in fish gills migrated into the ear canal millions of years ...

Biologists find no link between fish size and gill surface area—study suggests that models underlying some projections of future fisheries yields need to be reconsidered AMHERST, Mass. – A ...
