Balaenoptera is a diverse genus and comprises all but one of the extant species in its family—the other species is the humpback whale (Megaptera novaeangliae). This genus is known in the fossil records from the Neogene to the Quaternary (age range: from 13.65 million years ago to the present). Basic facts about Humpback Whale: lifespan, distribution and habitat map, lifestyle and social behavior, mating habits, diet and nutrition, population size and status. the age of individual humpback whales from any population with better than decadal resolution using this approach. KEY WORDS: Humpback whale · Megaptera novaeangliae · Ageing · Blubber · Biopsy sampling · Among odontocetes, age of sexual maturity ranges from a low of 2 to 3 years for the franciscana (Pontoporia blainvillei), 3 to 6 years for members of the family Phocoenidae, 3 to 12 years for Delphinidae, Monodontidae, and Ziphiidae, and 7 to 13 years for the sperm whale (Physeter macrocephalus).

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. The mean observed age of 10.01 years was used for estimation of the negative exponential distribution of age shown in (B).
the age of individual humpback whales from any population with better than decadal resolution using this approach. KEY WORDS: Humpback whale · Megaptera novaeangliae · Ageing · Blubber · Biopsy sampling · For example, using tissues obtained from free-ranging humpback whales Megaptera novaeangliae and bottlenose dolphins Tursiops truncatus from well-studied populations, techniques are currently being developed to assign individual whales to general age classes (as well as to an estimated age), by examining the length of short, repeated sequences The ability to determine the age of individual humpback whales Megaptera novaeangliae and estimate population age distributions is fundamental to assessments of status and long-term viability. Todd R. Robeck, Justine K. O'Brien, inEncyclopedia of Marine Mammals (Third Edition), 2018. BFemale Reproduction. Sexual maturity in mysticetes has been estimated to occur from 4–6 years for humpback whales (Megaptera novaeangliae), and ranges from 4 to 11 years for rorquals (family Balaenopteridae). We analysed telomere length in skin samples from 28 North Atlantic humpback whales (Megaptera novaeangliae), ranging from 0 to 26 years of age.
