The North Atlantic Right Whale can easily be identified by the white calluses on its head, which are very noticeable against the whale’s dark gray body. It has a broad back without a dorsal fin and a long arching mouth that begins above the eye. A baleen whale, it feeds by swimming through a swarm of plankton with its mouth open and the head slightly above the surface. Right whales are found more often in coastal waters, especially during the breeding season.
