Newborns are usually 4 to 5 m long, and are suckled by their mothers for about 5 months. ABSTRACT: The ability to determine the age of individual humpback whales Megaptera novaean-gliae and estimate population age distributions is fundamental to assessments of status and long-term viability. Existing methods of ageing large whales rely either on limited longitudinal sighting studies maturity at age 5 to 12 (Clapham 1992; Gabriele et al. 2007), and females give birth on average every 2 to 3 years (Clapham and Mayo 1987).
