The mitochondrial genome of the red icefish ( Channichthys rugosus ) casts doubt on its species status
Antarctic notothenioid fishes are recognised as one of the rare examples of adaptive radiation in the marine system. Withstanding the freezing temperatures of Antarctic waters, these fishes have diversified into over 100 species within no more than 10-20 million years. However, the exact species ric...
