In this case, total percent lipid showed a gradual decrease with increasing age (∼0.8% reduction in lipid per year of age). A decrease in lipid with age was also observed in the blubber of male fin whales 66. Determining the age of wild animals is very important in the study of their ecology and for stock assessment and management.

Humpback whales feed on small schooling fish of age) were 9.9 m (males) and 9.7 m (females). Mean lengths at the average age at attainment of sexual maturity (five years) were 11.8 m (males) and 11.9 m (females).

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. The mean observed age of 10.01 years was used for estimation of the negative exponential distribution of age shown in (B). 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.

from known-age whales from 2 distinct populations (North Atlantic, Gulf of Maine, n = 39; North Pacific, Southeast Alaska, n = 31), and analyzed for their fatty acid (FA) compositions. Multilinear FA-age models were derived for these known-age whales, and serve as the basis from which the age of unknown-age whales can be estimated.

Humpback whales (Megaptera novaeangliae, ‘humpbacks’) are one of the best studied cetacean species. However, they display no accurate visual markers for age after they are weaned at about 1 year (Chittleborough 1959) and lack of age information continues to limit our understanding of them. The largest fin whales can grow to 27.3 m (89.6 ft) long and have a maximum estimated weight of about 114 tonnes (126 short tons).

Female humpbacks reach reproductive maturity at age 5 while males at age 7. Effective July 2, 2001, NOAA Fisheries issued a final rule to establish measures to protect humpback whales, Megaptera novaeangliae, in waters within 200 nautical miles (370.4 km) of Alaska. Under these regulations it is unlawful for a person subject to… Humpback whale, (Megaptera novaeangliae), a baleen whale known for its elaborate courtship songs and displays. 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.

Newborns are usually 4 to 5 m long, and are suckled by their mothers for about 5 months. Epigenetic estimation can be used to estimate age in humpback whales, producing age distributions close to the expected values .
