Southern right whale

Eubalaena australis

The southern right whale is a mammal of the order Cetacea, the group that includes whales, dolphins and porpoises. It belongs to the suborder Mysticeti, which brings together the great whales that use baleen plates to filter their food.

Its body is black or dark gray with irregular white patches on the belly, although it can also show depigmentation on other parts of the body.

The most distinctive feature of these whales is the callosities on the top and sides of the head, made of hardened, horn-like skin.

Breeding and calving

The peninsula becomes a great nursery

Mating also takes place in these waters, and it´s a spectacular event. Mating groups of several individuals usually form.

Female right whales are thought to reach sexual maturity at around 7 years of age and to have a calf every 3 years. Gestation lasts about a year, and the first calves are born from June through mid-September. During that time the peninsula becomes a great nursery where the calves spend their first months of life.

The female often rolls belly-up to avoid mating, but when she has to turn over to breathe, the males immediately dive and try to mate with her. Males compete intensely for the female, although they may also work as a team during courtship.
