In the absence of fossils, the origin of Notothenioidei, a perciform suborder dominating the fish fauna of the Southern Ocean, remains conjectural; some morphoecological evidence suggests relationships to zoarcoids. To test this point we have compared the karyotype morphology and genome size of two species of zoarcids from the Ross Sea to those of one species each of the notothenioid families Artedidraconidae, Bathydraconidae, Channichthyidae and Nototheniidae from the same region. A karyotype… CONTINUE READING
