What is the maximal age a Bearded seal reaches?
An adult Bearded seal (Erignathus barbatus) usually gets as old as 31.42 years.
Bearded seals are around 281 days in the womb of their mother. When born, they weight 34.52 kg (76.1 lbs) and measure 100 cm (3′ 4″). As a member of the Phocidae family (genus: Erignathus), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 2.3 meter (7′ 7″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
The bearded seal (Erignathus barbatus), also called the square flipper seal, is a medium-sized pinniped that is found in and near to the Arctic Ocean. It gets its generic name from two Greek words (eri and gnathos) that refer to its heavy jaw. The other part of its Linnaean name means bearded and refers to its most characteristic feature, the conspicuous and very abundant whiskers. When dry, these whiskers curl very elegantly, giving the bearded seal a “raffish” look.Bearded seals are the largest northern phocid. They have been found to weigh as much as 300 kg with the females being the largest. However, male and female bearded seals are not very dimorphic.The only member of the genus Erignathus, the bearded seal is unique in that it is an intermediate. Bearded seals belong to the family Phocidae which contains two subfamilies: Phocinae and Monachinae. The bearded seal possesses characteristics of both of these subfamilies.Fossils first described in 2002 indicated that, during the Pleistocene epoch, bearded seals ranged as far south as South Carolina.
