notothenioidei

Suborder Notothenioidei (sometimes included in Percoidei)

"Notothenioidei (Southern Cod-Icefishes)".

The Antarctic silverfish, Pleuragramma antarcticum, is a member of the suborder Notothenioidei of the perciform fishes.

Comparing the genomes of Notothenioidei, which lack red blood cells, to close relatives, such as the Antarctic rockcod, has revealed genes needed to make these blood cells.

The Antarctic icefish belong to the perciform suborder Notothenioidei and are the largely endemic, dominant fish taxa in the cold continental shelf waters surrounding Antarctica.
