(NaturalNews) Otters have had issues verging on threatened extinction in the early 20th Century. They were trapped and killed for their thick-layered furs that protect them from water and frigid conditions. Restrictions or bans on killing otters for fur has helped their numbers rise again.
In addition to the thick double-layered furs that protect these semi-aquatic amphibious mammals of the weasel family, they have webbed feet with claws at the ends of their four short legs and a wide tail that helps propel them through water. The sea otters tend to spend more time in water then their river otter cousins.
