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 ...

Have you ever wondered why our ears look the way they do? That soft, curved shape we rarely think twice about might actually carry a hidden story– one that traces all the way back to life under the ...

Recent explorations into aquatic biology have unveiled a surprising reality: fish, despite being creatures of water, can ...

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 ...

Gill evolution Fish gills evolved to balance pH, not breathe, suggests a new study. This goes against the traditional assumption that gills first evolved so fish could get more oxygen as they became ...

I think the gills allow fish to breathe because water goes in them. Because they have holes in their gills so it is like a nose. But I don’t know how they stay alive if we can’t with our nose. Well if ...

Fish induce production of a particular antibody in their gills in response to pathogen exposure, researchers report at the conclusion of work that could lead to improved fish vaccines for aquaculture.
