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.

Fish can suffocate and die from oxygen deprivation, even when surrounded by water. This occurs when dissolved oxygen levels ...

A widely debated topic in biology and fisheries sciences is the role of oxygen in the growth of fish and other water-breathing animals. According to new research, developmental changes in individual ...

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 ...

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 ...

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 ...
