What is the maximal age a Eurasian beaver reaches?
An adult Eurasian beaver (Castor fiber) usually gets as old as 25 years.
Eurasian beavers are around 106 days in the womb of their mother. When born, they weight 551 grams (1.21 lbs) and measure 1.7 cm (0′ 1″). As a member of the Castoridae family (genus: Castor), a Eurasian beaver caries out around 2 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 75.7 cm (2′ 6″).
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 beaver (Castor fiber) or European beaver is a beaver species that was once widespread in Eurasia, but was hunted to near-extinction for both its fur and castoreum. At the turn of the 20th century, only about 1,200 beavers survived in eight relict populations in Europe and Asia. It has been reintroduced to much of its former range, and now occurs from Spain, Central Europe, Great Britain and Scandinavia to a few regions in China and Mongolia. It is listed as least concern on the IUCN Red List, as it recovered well in most of Europe. It is extinct in Portugal, Moldova, and Turkey.
