Notothenioid fish
Nototheniidae species are largely found in the Southern Ocean and are particularly abundant off the shores of Antarctica. As the dominant Antarctic fish taxa, they occupy both sea-bottom and water-column ecological niches. Nototheniidae is a family of teleost fishes found mainly in the Southern Ocean, surrounding the continent of Antarctica. The family comprises about 50 species of fish that are adapted to living … WebThe Notothenioids comprise about half of Antarctic marine fish species, but they account for 95% of all fish biomass in the region. How did these fish come to be the dominant fish species? Scientists believe that the dominance of these fish is a product of genetic and geological history.
