Studies of the hemoglobin system of fish of the suborder Notothenioidei have been extended to non-Antarctic species of Pseudaphritis urvillii and Notothenia angustata. The two species belong to families that were the first to diverge within the suborder. The degree of amino acid sequence identity with Antarctic notothenioids and other non-Antarctic fish species is analyzed with respect to phyletic and ecological diverence.
