Right whales are quite rare to see and are physically very different from other species of whale.
The number, distribution, and size of the callosities varies among individuals, and they are often used for identification. The body is dark to light gray, appearing mottled, with whitish underparts. Right whales strain plankton with baleen plates which may reach 7 feet in length. Because the two blowholes are widely separated, the spout is seen as two distinct sprays. Right whales reach sexual maturity between 3-5 years of age.
