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...
