ABSTRACT: Reports of humpback whales, Megaptera novaeangliae, that 1996 were analyzed to determine age class (estimated from body length and/or.
Humpback whales spend the Age-related multi-year associations in female humpback whales (Megaptera novaeangliae) Abstract: Analyses of social structures in baleen whales are rare, and so far, they are thought to consist of mostly short and unstable associations. Using skin biopsies once again, they measured the epigenetic ages of 63 humpback whales migrating north near Evans Head, Australia, and observed an average population age of 10 years, with a total age range from 0 to 52 years. Age estimates generated by the HEAA for east Australian humpback whales. (A) Population age distribution estimated with the HEAA for N = 63 noncalf whales samples near Evans Head. Ages are grouped into categories of 4 years.

1992 Age at attainment of sexual maturity in humpback whales. Can. J. Zool. (Megaptera novaeangliae) observed in Massachusetts Bay: 1979–1985. Can. J.
Humpbacks usually range from 12 to 16 metres (39 to 52 feet) in length and weigh approximately 36 metric tons (40 short [U.S.] tons). We analysed telomere length in skin samples from 28 North Atlantic humpback whales (Megaptera novaeangliae), ranging from 0 to 26 years of age. The results suggested a significant correlation between telomere length and age in humpback whales.

The maximum estimated age was a 115-year-old (±10 SE) female. Asymptotic body length was estimated to be 396 cm for females and 457 cm for males, and asymptotic body mass was estimated to be 904 kg for females and 1,645 kg for males. Average weaning age 5 months; Range age at sexual or reproductive maturity (female) 4 to 5 years; Range age at sexual or reproductive maturity (male) 4 to 5 years; Calves are born in the warm tropical waters and subtropical waters of each hemisphere. Newborns are usually 4 to 5 m long, and are suckled by their mothers for about 5 months.
