Abstract The body‐size scaling pattern of enzymes that are important in energy metabolism was examined in gills of the blue crab as a function of acclimation salinity. We hypothesized that the higher ...

Gills are best known for helping most fish species breathe underwater. But less well known is the fact gills regulate the salt and pH balance of fishes’ blood, a vital role played by the kidneys in ...

An imaging study of exceptionally well-preserved trilobite fossils shows that specific filaments on the upper limb of these marine creatures performed a respiratory function 1. The upper-limb ...

The genetic toolkit that animals use to build fins and limbs is the same genetic toolkit that controls the development of part of the gill skeleton in sharks, according to research to be published in ...
