Japanese beaver

The Japanese beaver, also known as the Shikoku beaver, is a small subspecies of the Eurasian beaver that is only native to Shikoku in Japan and is a good thing they aren't endangered but they are vulnerable. The European otter is also only found in Shikoku. In some range maps of the Eurasian beaver, it is not found in Shikoku. The California beaver (Castor Californicus) is a prehistoric ancestor of the North American beaver. The Eurasian beaver usually lives from The UK to China and Mongolia and although it is absent in Italy, Portugal, The Southern Balkans, and The Middle East or M.E. for short. The otters of Japan including the Japanese river otter, Japanese otter, and European otter would have been able to compete with the beavers by killing the pups like other otters do to other beavers. The North American beaver is also known as the American beaver or Canadian beaver and the Eurasian beaver is also known as the European beaver or Asian beaver. The North American river otter and North American beaver have the same last word of their scientific names including Canadensis and they are also known as the Canadian otter and beaver. The North American otter is also known as the Northern, Common, or Canadian otter. Beavers don't usually live in Japan but they used to live in Britain, China, Mongolia, Italy, Portugal, The Southern Balkans, and the Northern Middle East. The North American beaver and American mink have both been introduced to Europe. Unlike other beavers, the Japanese probably make the smallest dams. Taken in a Japanese zoo, this shows you the dark color and small size. The British beavers became extinct in 1526 but good news; they have returned to Scotland, China, Mongolia, Italy, Portugal, Southern Balkans, and the Northern Middle East.
