| Summary: | Abstract Notothenioids represent an adaptive radiation of teleost Ashes in the frigid waters of the Southern Ocean surrounding Antarctica (1). Of the 129 recognized species, 101 are found in marine costal habitats of Antarctica (Fig. 1), and the remaining species are distributed along costal areas of southern South America, the Falkland Islands, southern New Zealand, southern Australia, and Tasmania (2). In addition to a diverse array of adaptations to survive in the freezing Antarctic marine habitats, notothenioids are unique in that they completely dominate the Ash fauna of the Southern Ocean. Among benthic Ash samples taken on the Antarctic shelf, notothenioids comprise nearly 77% of the species diversity, more than 91% of the species abundance, and 91% of the biomass (3). |
