How will fish that evolved at constant sub‐zero temperatures cope with global warming? Notothenioids as a case study [PDF]
BioEssays, 2011 Current climate change has raised concerns over the fate of the stenothermal Antarctic marine fauna (animals that evolved to live in narrow ranges of cold temperatures).

Characterization of cortical alveoli content in several species of Antarctic notothenioids [PDF]
Journal of Fish Biology, 2005 Cytochemical analyses was used to study the organization and content of cortical alveoli in eight species of Antarctic teleosts belonging to three different families of notothenioids: nototheniids, bathydraconids and channichthyids.

Checklist of the species of notothenioid fishes
Antarctic Science, 2021AbstractWe provide our perspective on the species-level taxonomy of notothenioid fishes, the dominant component of the fish fauna of Antarctica. There are 140 species in 45 genera, an increase of 15% since the previous summary in 2000. Biogeographically, 30 species are non-Antarctic, 33 are sub-Antarctic and 77 are Antarctic.

Structure and expression of genes involved in transport and storage of iron in red-blooded and hemoglobin-less antarctic notothenioids [PDF]
Gene, 2007 Antarctic notothenioids are characterized by a drastic reduction of the hemoglobin content, a condition that reaches its extreme in icefish that, following a gene deletion event, are completely devoid of hemoglobin. To answer the question on what type of

In vitro cardiac performance in the sub-antarctic notothenioids Eleginops maclovinus (subfamily eleginopinae), Paranotothenia magellanica, and Patagonotothen tessellata (subfamily nototheniinae) [PDF]
Comparative Biochemistry and Physiology A, Comparative Physiology, 1997 There is lack of information concerning species diversification in the Non-Antarctic Nototheniid fish both in relation with their variation in organismal performance and in the morphofunctional characteristics underlying this variation.

Molecular adaptations in haemoglobins of notothenioid fishes
Journal of Fish Biology, 2010Since haemoglobins of all animal species have the same haem group, differences in their properties, including oxygen affinity, electrophoretic mobility and pH sensitivity, must result from the interaction of the prosthetic group with specific amino‐acid residues in the primary structure.

Morphometrics and ultrastructure of myocardial tissue in Notothenioid fishes
Fish Physiology and Biochemistry, 1987Antarctic fish of the family Channichthyidae (Icefishes) lack the respiratory pigments haemoglobin and myoglobin. The morphometrics and ultrastructure of the ventricular myocardium of a benthic icefish,Chaenocephalus aceratus has been compared with that of a red-blooded Notothenioid fish,Notothenia neglecta, of similar habit.The mass of ventricular ...
