A new species of plunderfish Pogonophryne favosa sp. n. from the mesobenthal of the Cosmonauts Sea, Antarctica, has been described. The new species belongs to a group of species “mentella”, differing from other species of the group in the presence of spots on the abdominal side of the body and a unique structure of mental barbel. An anatomohistological study was performed of convexitas superaxillaris—unusual skin formations first found in Artedidraconidae. Their possible function in the system… 
Morphological description of long-finned Dollo’s plunderfish Dolloidraco longedorsalis (Artedidraconidae, Notothenioidei) from marginal seas of Antarctica
Based on the materials of several Russian and German Antarctic expeditions, a detailed description of external morphology, seismosensory system, and axial skeleton of long-finned Dollo’s plunderfish Dolloidraco longedorsalis is presented.
Checklist of the species of notothenioid fishes
The perspective on the species-level taxonomy of notothenioid fishes, the dominant component of the fish fauna of Antarctica, is provided, with an increase of 15% since the previous summary in 2000.
Reproductive traits and age of barbeled plunderfishes from the Weddell Sea
New data is provided on the age and reproductive traits of some species of Pogonophryne from the southern Weddell Sea, inferred through otolith reading and histological analyses of gonads.
Phylogenomic species delimitation dramatically reduces species diversity in an Antarctic adaptive radiation.
This work integrates phylogenetic, population genetic, and coalescent analyses of genome-wide sequence data with investigation of variation in multiple morphological traits to delimit species within the Antarctic barbeled plunderfishes (Artedidraconidae: Pogonophryne).
An analysis of maximum body size and designation of size categories for notothenioid fishes
With the exception of miniature species, the 126 species of cryonotothenioids encompass the range in size categories in actinopterygians in general, and the disparity in maximum lengths among individual species indicates that body size is an axis of the radiation.


Lateral Transfer of a Lectin-Like Antifreeze Protein Gene in Fishes
It is proposed that lateral gene transfer has resulted in the occurrence of the type II AFPs in herring, smelt and sea raven and allowed these species to survive in an otherwise lethal niche.
Ancient climate change, antifreeze, and the evolutionary diversification of Antarctic fishes
The results challenge the current understanding of the evolution of Antarctic notothenioids suggesting that the ecological opportunity that underlies this adaptive radiation is not linked to a single trait, but rather to a combination of freeze avoidance offered by AFGPs and subsequent exploitation of new habitats and open niches created by increased glacial and ice sheet activity.
Convergent evolution of antifreeze glycoproteins in Antarctic notothenioid fish and Arctic cod.
Molecular evidence for separate ancestry is supported by morphological, paleontological, and paleoclimatic evidence, which collectively indicate that these two polar fishes evolved their respective AFGPs separately and thus arrived at the sameAFGPs through convergent evolution.
Aspects of Eco-Physiological Adaptations in Antarctic Fish
Organisms exhibit a diversity in lipid structures to fashion membranes to prevailing ambient temperatures in such a manner that they become more fluid in a cold-ac Climatized state than in a warm-acclimatization state.
Nonhepatic origin of notothenioid antifreeze reveals pancreatic synthesis as common mechanism in polar fish freezing avoidance
It is found the exocrine pancreas to be the major site of AFGP synthesis and secretion in all life stages, and that pancreatic AFGPs enter the intestinal lumen via the pancreatic duct to prevent ingested ice from nucleating the hyposmotic intestinal fluids.
Fish antifreeze proteins: physiology and evolutionary biology
Many marine teleosts have adapted to ice-laden seawater by evolving antifreeze proteins and glycoproteins. These proteins are synthesized in the liver for export to the blood where they circulate at
Synthesis and recycling of antifreeze glycoproteins in polar fishes
It is shown that Antarctic notothenioids and Arctic gadids both accumulate AFGPs within ellipsoidal macrophages of the spleen, presumably adsorbed to phagocytosed ice crystals which are then held until a warming event ensues.
Antifreeze glycopeptides and peptides in Antarctic fish species from the Weddell Sea and the Lazarev Sea
The structural diversity of antifreeze molecules and their occurrence in a wide range of Arctic and Antarctic fish species suggest that they evolved from precursor proteins before the continental drift and recently during Cenozoic glaciation into the various antifreesze molecules.
Herring antifreeze protein: primary structure and evidence for a C-type lectin evolutionary origin.
Results suggest that herring AFP is structurally and functionally similar to the CRDs of C-type lectins and related domains in other proteins.
