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 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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Oriol Sunyer, a professor at the University of Pennsylvania School of Veterinary Medicine, has described fish as 'an open gut swimming'. Their mucosal surfaces - their skin, digestive tract and gills ...
