| Abstract |
This paper summarizes data on comparative morphology, describes patterns and main trends in evolutionary development that are important for the growth of systems of organs, and defines the polarity of morphoclines of more than 250 systematic characters of the notothenioid fishes (suborder Notothenioidei). New and unusual skin organs, such as the antcsupracleithral organ, internasal organ and hypoglossal gland glandulae hypoglossus found in notothenioids, arc described in detail. The cladogenetic similarity, sequence, and pattern of the branching of the higher (above genus) taxons of the suborder arc evaluated by the methods of phylogenetic systematics (Hennig's cladistics). New phylogenetic relationships for families of the suborder and therelationships among genera in polytypic families (subfamilies) of the Notothenioidei are proposed. The taxonomic structure of the suborder is refined. The suborder comprises 8 families, 48 genera, and 139 species. Key points in the historical development and dispersal of notothenioids in the Quaternary Period, as well as the possible prerequisites that arc necessary for the biological progress of notothenioid fish, which occupy a dominant place in the Antarctic ichthyofauna. are discussed. |
