Short description Morfologi

The northern right whale is one of the stockiest of all whales. It has a massive head that can be up to nearly one-third of its body length. The jaw line is arched and the upper jaw is very narrow in dorsal view. The flippers are broad and tend to be more fan-shaped than the pointed flippers of most other cetaceans. There is no dorsal fin or dorsal ridge on the broad back. The flukes are very wide and smoothly tapered, with a smooth trailing edge and a deep notch. Most right whales are predominantly black, but there may be large white splotches of varying extent on the belly and chin. The head is covered with callosities, areas of roughened skin to which whale lice and sometimes barnacles attach. The largest of these callosities, on the top of the rostrum, is called the bonnet. The widely separated blowholes produce a Vshaped blow up to 5 m high. Inside the mouth are 200 to 270 long thin baleen plates. Which may reach nearly 3 m in length. They are brownish grey to black in colour. The fringes of these plates are very fine, reflecting the small prey taken by this species.

Biologi     Ordlista (t.ex. epibenthic)

The right whales were the first targets of commercial whaling, starting in the eleventh century. They were sought after because of their thick blubber layer (and thus high yield of oil), long flexible baleen (used for many of the same purposes as plastic is today), slow swimming speeds, and tendency to float when killed. North Pacific right whales were depleted to near extinction by commercial whaling, the most recent episodes of which occurred as scientific whaling about 20 years ago. Sightings today are rare, apparently the species is not recovering, even under full protection (Ref. 1394). Calving and feeding areas throughout the world are most often in shallow nearshore regions. Seen in groups of less than 12 (most often singles or pairs). Feed on copepods and other small invertebrates, generally by slowly skimming through patches of concentrated prey at or near the surface (Ref. 1394). It is preyed upon by the sevengill shark (Ref. 8910).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Eggs | Fecundity | Larvae

The mating system appears to involve sperm competition (males competing to inseminate females, not so much by physical aggression, as by delivering large loads of sperm, thereby displacing that of other males). Young are born in winter and spring in tropical or subtropical breeding areas.
