What is the maximal age a Eurasian otter reaches?
An adult Eurasian otter (Lutra lutra) usually gets as old as 22 years.
Eurasian otters are around 64 days in the womb of their mother. When born, they weight 285 grams (0.63 lbs) and measure 1.2 meter (4′ 0″). As a member of the Mustelidae family (genus: Lutra), a Eurasian otter caries out around 2 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 68.9 cm (2′ 4″).
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 Eurasian otter (Lutra lutra), also known as the European otter, Eurasian river otter, common otter, and Old World otter, is a semiaquatic mammal native to Eurasia. The most widely distributed member of the otter subfamily (Lutrinae) of the weasel family (Mustelidae), it is found in the waterways and coasts of Europe, many parts of Asia, and parts of northern Africa. The Eurasian otter has a diet mainly of fish, and is strongly territorial. It is endangered in some parts of its range, but is recovering in others.
