Why are fish getting smaller as waters warm? It's not their gills Date: February 26, 2024 Source: University of Massachusetts Amherst Summary: A collaborative team of scientists recently found ...

In tadpoles, both human ear and fish gill enhancers showed activity in their gills. In lizards, a related program was active in a small bone-like structure in their middle ears.

Baby Japanese eels have been spotted escaping from the stomachs of fish that have eaten them by backing out tail-first, as if moonwalking, first out of their esophagus and then their gills ...

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.

But some fish don’t have gills or only use them part-time. They might breathe air using lungs like us. That’s how African Lungfish breathe. They rise to the surface and grab a gulp of air.

After they were swallowed, all but four of the eels tried to get out by going back through the fish’s digestive tract toward its esophagus and gills. Of those, 13 managed to get their tails out ...

It turns out the human ear got off to a fishy start. Literally. A fascinating new study reveals that the mammalian outer ear has its evolutionary roots in the gills of ancient fish. This surprising ...

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 ...

Gills and outer ears look and function quite differently from one another. They also do not mineralize, which means they are rarely recovered in the fossil record.

For nearly 20 years, Sunyer's lab has contributed a steady stream of discovery regarding the evolution and roles of the immune system using fish as model species.
