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.

Fish physiologists have provided the basic information on gill morphology, gill function, and vascular dynamics with which to understand branchial flux of gases, water, and ions. In addition, ...

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

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
