Females reach sexual maturity at 6–12 years and breed every 3–5 years. Both reproduction and calving take place during the winter months. An individual female mates with multiple males. Apparently, mating pairs do not establish long-term social bonds
Calves are approximately 1 tonne (1.1 short tons) in weight and 4–6 m (13–20 ft) in length at birth following a gestation period of 1 year. The right whale grows rapidly in its first year, typically doubling in length. Weaning occurs after eight months to one year and the growth rate in later years is not well understood—it may be highly dependent on whether a calf stays with its mother for a second year.
Southern Right Wale Mating [video]
Southern right whales belong in separate breeding groups which travel to their own areas to reproduce. Up to eight males may mate with one female between July and August, but unusually for mammals, aggression between males is minimal. Females calve once every three years between June and August, with a gestation period of 11 to 12 months. Calving females go for four months during the winter months without eating, and give birth to a single, large calf weighing up to 1,500 kilograms. Females will nurture and feed their calves in the shallows where they are well protected from attacks by orcas and great white sharks. Calves are weaned after a year, and will reach sexual maturity at nine to ten years.
