Mitochondrial function in Antarctic nototheniids with ND6 translocation.
PLoS ONE, 2012 Fish of the suborder Notothenioidei have successfully radiated into the Southern Ocean and today comprise the dominant fish sub-order in Antarctic waters in terms of biomass and species abundance. During evolution in the cold and stable Antarctic climate,

Evolution and Function of the Globin Intergenic Regulatory Regions of the Antarctic Dragonfishes (Notothenioidei: Bathydraconidae) [PDF]
Molecular Biology and Evolution, 2011 As the Southern Ocean cooled to -1.8 °C over the past 40 My, the teleostean clade Notothenioidei diversified and, under reduced selection pressure for an oxygen-transporting apparatus, became less reliant on hemoglobin and red blood cells. At the extreme of this trend, the crown group of Antarctic icefishes (Channichthyidae) lost both components of ...

Age, growth and distribution of the Antarctic fish Chaenocephalus aceratus based on otoliths
Frontiers in Marine Science, 2015 The Chaenocephalus aceratus were sampled in the summer between 1979 and 1990 at South Georgia Is. The problems of ageing Antarctic fish Channichthyidae are commonly known (Kock, 1989; Le_François, 2014; Campana, 2014) they have not scales and their bones

Structure and function of hemoproteins from cold-adapted organism [PDF]
, 2011 Environmental oxygen availability certainly plays a key role in the evolution of polar marine life, as suggested by the physiological and biochemical strategies that the organisms have adopted to acquire, deliver and scavenge oxygen.
