| 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. |
