Morphological diversity among some of the 48 species of the notothenioid family Nototheniidae:
 
 
 
   
a. Notothenia angustata, heavy inshore benthic and rockpool species with a cold temperate and Subantarctic distribution.
   
b. Adult Notothenia microlepidota, rocky reef dwelling benthic species with a Subantarctic distribution.
   
c. Pelagic juvenile of N. microlepidota with silvery colouring and forked caudal fin, frequently captured far from shore.
   
d. Patagonotothen elegans, small blenny-like species from southern South America.
   
e. Gobionotothen gibberifrons, benthic species common near the Antarctic Peninsula.
   
f. Trematomus bernacchii, high Antarctic inshore benthic species.
   
g. Trematomus scotti, high Antarctic offshore benthic species.
   
h. Typical morph of Trematomus newnesi, a semipelagic Antarctic species.
   
i. Trematomus loennbergii, epibenthic Antarctic species living near the bottom at depths of 663-1191 m.
   
 j. Pagothenia borchgrevinki, cryopelagic Antarctic species living near the platelet layer underlying fast sea ice.
   
k. Dissostichus eleginoides, large Subantarctic piscivorous predator probably close to neutral buoyancy and living at depths to 1500 m. This is the "Chilean sea bass" of restaurants and fish markets.
   
l. Pleuragramma antarcticum, shoaling neutrally buoyant zooplanktivore, the dominant species in the water column (0-900 m) of the high Antarctic shelf.
