摘要：

Comparison of partial mitochondrial 12S and 16S rDNA sequences from non-Antarctic notothenioid fishes - an icefish Champsocephalus esox and two members of the genus Patagonotothen - and their sister species from the Southern Ocean suggests that their divergence took place 1.7 and 6.6-7 million years ago, respectively, i.e. much later than the formation of the Antarctic Polar Front (20-25 million years ago).
