Akarotaxis gouldae, a new species of Antarctic dragonfish (Notothenioidei: Bathydraconidae) from the western Antarctic Peninsula.

Zootaxa
Bathydraconidae (Notothenioidei) are a group of benthic fishes endemic to the Southern Ocean. Because of their recent evolutionary radiation and limited sampling efforts due to their occurrence in remote regions, their diversity is likely underestimated.

Developmental constraint shaped genome evolution and erythrocyte loss in Antarctic fishes following paleoclimate change.

PLoS Genetics, 2020
In the frigid, oxygen-rich Southern Ocean (SO), Antarctic icefishes (Channichthyidae; Notothenioidei) evolved the ability to survive without producing erythrocytes and hemoglobin, the oxygen-transport system of virtually all vertebrates.

Overview of Antarctic icefish species of the genus Channichthys Richardson, 1844 (Notothenioidei: Channichthyidae) based on morphological studies

Biological Communications
The study presents the results of a most recent comprehensive review of the morphology of little-studied endemic Antarctic icefishes of the genus Channichthys Richardson, 1844 (family Channichthyidae). It aims at a detailed taxonomic revision in order to

Studies on morphology and osteology of Parachaenichthys georgianus (Fischer, 1885) (Notothenioidei, Bathydraconidae) from shelf waters off South Georgia (Antarctica) [PDF]

Acta Ichthyologica et Piscatoria, 1994
Body length-dependent variability of the 5 following characteristics, commonly regarded as diagnostic, was studied: head length, maximum body depth, interorbital distance, horizontal eye diameter, and snout length.

Comparative morphology and evolutionary transformations of the neurocranium of thornfishes (Perciformes: Notothenioidei, Bovichtidae)

Proceedings of the Zoological Institute RAS
The structure of the neurocranium of 8 species from 3 genera of notothenioid fishes of the family Bovichtidae (Bovichtus Valenciennes, 1832, Cottoperca Steindachner, 1875, and Halaphritis Last, Balushkin et Hutchins, 2002) was studied in comparison with ...

Projected Warming of the Southern Ocean Disrupts Embryonic Development and Hatch Timing in Antarctic Fish

Global Change Biology Communications, Volume 1, Issue 1, March 2026.
Embryos are particularly sensitive to thermal challenge. Antarctic fish embryos raised at projected Southern Ocean temperatures hatch during the winter, have a high incidence of morphological abnormalities, have shorter body lengths, and express genes indicative of cellular stress.

On some biological characters of Parachaenichthys georgianus (Fischer,1885) (Pisces, Notothenioidei, Bathydraconidae) from the shelf waters of South Georgia (Antarctica) [PDF]

Acta Ichthyologica et Piscatoria, 1994
The present paper evaluates the relevance of otoliths, vertebrae and other osseous elements to the age determinations; the age composition of stock, growth rate, length-weight relationship, condition, stage of gonads maturity as well as the age at first ...

The Weddell Gyre, Southern Ocean: Present Knowledge and Future Challenges

Reviews of Geophysics, Volume 57, Issue 3, Page 623-708, September 2019., 2019
Abstract The Weddell Gyre (WG) is one of the main oceanographic features of the Southern Ocean south of the Antarctic Circumpolar Current which plays an influential role in global ocean circulation as well as gas exchange with the atmosphere. We review the state‐of‐the art knowledge concerning the WG from an interdisciplinary perspective, uncovering ...
