Research links evolution of fins and limbs with that of gills

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 Proceedings of the National Academy of Sciences on March 23, 2009, by Andrew Gillis and Neil Shu...

Thin tough skin, slow-growing gills protect larval Antarctic fish

Very thin but hardy, unblemished skin and slow developing gills appear to be keys to survival for newly hatched Antarctic notothenioids, a group of fish whose adults thrive in icy waters because of antifreeze proteins (AFPs) in their blood. Such adaptations are important, researchers at the Unive...
