The right whales were first classified in the genus Balaena in 1758 by Carl Linnaeus, who at the time considered all of the right whales (including the bowhead) as a single species. Through the 19th and 20th centuries, in fact, the family Balaenidae has ...
Like other right whales, the North Atlantic right whale, also known as the northern right whale or black right whale, [2] is readily distinguished from other cetaceans by the absence of a dorsal fin on its broad back, short, paddle-like pectoral flippers and a long arching mouth that begins above the eye.

The southern right whale (Eubalaena australis) is a baleen whale, one of three species classified as right whales belonging to the genus Eubalaena. Southern right whales inhabit oceans south of the Equator, between the latitudes of 20° and 60° south. [5] In 2009 the global population was estimated to be approximately 13,600. [6]
Right whales have rotund bodies with arching rostrums, V-shaped blowholes and dark gray or black skin. The most distinguishing feature of a right whale is the rough patches of skin on its head, which appear white due to parasitism by whale lice .
The pygmy right whale shares several characteristics with the right whales, with the exception of having a dorsal fin. Also, pygmy right whales' heads are no more than one quarter the size of their bodies, whereas the right whales' heads are about one-third the size of their bodies. [11] The pygmy right whale is the only extant member of its ...
The North Pacific right whale (Eubalaena japonica) is a very large, thickset baleen whale species that is extremely rare and endangered.. The Northeast Pacific population, which summers in the southeastern Bering Sea and Gulf of Alaska, may have no more than 40 animals.
With a population estimated at between 300-350 individuals, [19] the North Atlantic right whale is the most critically endangered great whale. The Northern Pacific right whale is also endangered with only about 500 individuals extant. [16] [17] The Southern right whale (~7500 individuals in 1997) and the Bowhead whale (20,000 to 40,000) have ...
