At least four subspecies of blue whale are traditionally recognized, some of which are divided into population stocks or "management units". [26] [27] They have a worldwide distribution, but are mostly absent from the Arctic Ocean and the Mediterranean, Okhotsk, and Bering Sea. [26] Aerial view of adult blue whale.

The pygmy blue whale is the only one of the three identifiable subspecies to be found regularly in tropical waters. It occurs from the sub-Antarctic zone to the southern Indian Ocean and southwestern Pacific Ocean, breeding in the Indian and South Atlantic oceans, and travelling south to above the Antarctic to feed, [4] [7] although they very rarely cross the Antarctic Convergence.
Four subspecies are recognized: B. m. musculus in the North Atlantic and North Pacific, B. m. intermedia in the Southern Ocean, B. m. brevicauda (the pygmy blue whale) in the Indian Ocean and the South Pacific Ocean, and B. m. indica in the Northern Indian Ocean. There is a population in the waters off Chile that may constitute a fifth subspecies.

The family Balaenidae, the right whales, contains two genera and four species. All right whales have no ventral grooves; a distinctive head shape with a strongly arched, narrow rostrum, bowed lower jaw; lower lips that enfold the sides and front of the rostrum; and long, narrow, elastic baleen plates (up to nine times longer than wide) with fine baleen fringes.
The IUCN also lists 31 mammalian subspecies as near threatened. Of the subpopulations of mammals evaluated by the IUCN, one species subpopulation and one subspecies subpopulation have been assessed as near threatened. This is a complete list of near threatened mammalian species and subspecies evaluated by the IUCN.
