How old does a Ross seal get? (age expectancy)

What is the maximal age a Ross seal reaches?

An adult Ross seal (Ommatophoca rossii) usually gets as old as 21 years.

Ross seals are around 325 days in the womb of their mother. When born, they weight 17 kg (37.48 lbs) and measure 5.1 cm (0′ 3″). They are a member of the Phocidae family (genus: Ommatophoca). Fully grown, they reach a bodylength of 2.07 meter (6′ 10″).

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.

A Ross seal gets as old as 21 years

The Ross seal (Ommatophoca rossii) is a true seal (family Phocidae) with a range confined entirely to the pack ice of Antarctica. It is the only species of the genus Ommatophoca. First described during the Ross expedition in 1841, it is the smallest, least abundant and least well known of the Antarctic pinnipeds. Its distinctive features include disproportionately large eyes, whence its scientific name (Ommato- meaning “eye”, and phoca meaning “seal”), and complex, trilling and siren-like vocalizations. Ross seals are brachycephalic, as they have a short broad muzzle and have the shortest fur of any other seal.
