Litter Size

How many babies does a Eurasian beaver have at once? (litter size)

How many baby Eurasian beavers are in a litter?

A Eurasian beaver (Castor fiber) usually gives birth to around 2 babies.With 1 litters per year, that sums up to a yearly offspring of 2 babies.

Each of those little ones spend around 106 days as a fetus before they are released into the wild. Upon birth, they weight 551 grams (1.21 lbs) and measure 1.7 cm (0′ 1″). They are a member of the Castoridae family (genus: Castor). An adult Eurasian beaver grows up to a size of 75.7 cm (2′ 6″).

To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.

The average litter size of a Eurasian beaver is 2

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.
