How old does a Commerson’s dolphin get? (age expectancy)

What is the maximal age a Commerson’s dolphin reaches?

An adult Commerson’s dolphin (Cephalorhynchus commersonii) usually gets as old as 18 years.

When born, they weight 5.84 kg (12.87 lbs) and measure 20 cm (0′ 8″). They are a member of the Delphinidae family (genus: Cephalorhynchus). Fully grown, they reach a bodylength of 87.5 cm (2′ 11″).

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 Commerson's dolphin gets as old as 18 years

Commerson’s dolphin (Cephalorhynchus commersonii), also referred to by the common names jacobita, skunk dolphin, piebald dolphin or panda dolphin, is a small oceanic dolphin of the genus Cephalorhynchus. Commerson’s dolphin has two geographically-isolated but locally-common subspecies. The principal subspecies, C.c.commersonii, has sharply-delineated black-and-white patterning and is found around the tip of South America. The secondary subspecies, C.c.kerguelenensis, is larger than C.c.commersonii, has a less-sharply delineated dark and light grey patterning with a white ventral band, and is found around the Kerguelen Islands in the Indian Ocean.The dolphin is named after French naturalist Dr Philibert Commerson, who first described them in 1767 after sighting them in the Strait of Magellan.
