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...

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 richness of the radiation remains contested. In the genus Channichthys, between one and nine species are recognised by different authors. To resolve the number of Channichthys species, genetic information would be highly valuable; however, so far, only sequences of a single species, C. rhinoceratus, are available. Here, we present the nearly complete sequence of the mitochondrial genome of C. rugosus, obtained from a formalin-fixed museum specimen sampled in 1974. This sequence differs from the mitochondrial genome of C. rhinoceratus in no more than 27 positions, suggesting that the two species may be synonymous. |
