AI overview

A bowhead whale is a large marine mammal found in Arctic waters, named for its distinctive bow-shaped head that it uses to break through ice. These whales are significant because they are long-lived animals that have adapted to survive in some of Earth's harshest environments.

Maximum longevity: 211 years (wild) Observations: These animals exhibit slow growth and high survival. Growth may be faster in females than in males, and it slows down markedly at around 40-50 years of age. Sexual maturity is probably reached at age 20-25. Using an indirect method for age estimation based on aspartic acid racemization, the bowhead whale has been recorded as the longest-lived mammal thanks to one male estimated to be 211 years-old. The same study found three other male specimens estimated to be over 100 years of age. Very few obvious signs of pathology were found in old bowheads. The 211 year-old specimen was reported to appear old with though meat and blubber. One of the centenarian males exhibited a spondylitic lesion on the vertebra. Reproductive senescence has not been reported, though detailed studies are lacking (George et al. 1999).

The bowhead whale (Balaena mysticetus), sometimes known as the Greenland right whale, Arctic whale, and polar whale, is a species of baleen whale belonging to the family Balaenidae and is the only living representative of the genus Balaena. It is the only baleen whale endemic to the Arctic and subarctic waters, and is named after its characteristic massive triangular skull, which it uses to break through Arctic ice.

Bowheads have the largest mouth of any animal, representing almost one-third of the length of the body. They also have the longest baleen plates among whales, with a maximum length of 2.97 to 5.2 metres (9.7 to 17.1 ft). They may be the longest-lived of all mammals, with the ability to reach an age of more than 200 years.
