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.

Researchers used powerful tech to analyse thousands of individual cells at once, considering which genes are active and how DNA is organised within each cell. The outer ears that sit on the sides of ...

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

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 ...

The lack of a suitable flat epithelial preparation isolated directly from the freshwater fish gill has led, in recent years, to the development of cultured gill epithelia on semipermeable supports. To ...

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 ...

Gas-exchange structures are critical for acquiring oxygen, but they also represent portals for pathogen entry. Local mucosal immunoglobulin responses against pathogens in specialized respiratory ...

In 1878, German anatomist Karl Gegenbaur proposed a theory that fish fins and human limbs evolved from a structure that resembles gill arches, a collection of bony "loops" in fish that support the ...

Sharks, skates and rays are oddities among fish: They have appendages growing out of the gill arches, small cradles of bones that supports the gills. This anatomical peculiarity has led to the ...

The outer ears that sit on the sides of your head share an unexpected genetic heritage with the gills of fish. According to research published in the journal Nature by scientists from the University ...
