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

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, ...

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.

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 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 ...
