Castor Fiber

The European beaver (Castor fiber) is a beaver species, one of the largest living rodent species and the largest rodent native to Eurasia. 

Its head-to-body length is 80–100 cm (31–39 in) with a 25–50 cm (9.8–19.7 in) long tail length.

The Eurasian beaver is recovering from near extinction, after depredation by humans for its fur and for castoreum, a secretion of its scent gland believed to have medicinal properties

Endangered species in Croatia, the European beaver population in Croatia was estimated to be 130–150.
