Unlike temperate fishes, Antarctic fishes of the notothenioid suborder, whose body temperatures (−2 to +1°C) conform to the Southern Ocean, must express their genomes in an extremely cold thermal regime. To determine whether these fishes have evolved compensatory adjustments that maintain efficient...
