Sea otters inhabit the seas and kelp beds of North America. The otter is a highly intelligent, playful, and inquisitive mammal. It is most famous for swimming on its back and using stones as tools to break open the hard shells of mollusks. Endangered because of its thick fur, this now protected relative of the mink is returning to stable population levels. Typically, sea otters measure up to 48 inches (121 cm) and weigh up to 90 pounds (40 kg).nnSpecifications:nn1: 1 scalennPolyurethane resin castn2-part skull (separate cranium and jaw)nnSkull Length 14.7 cm (5.8 in.)nSkull Width 10.9 cm (4.3 in.)nSkull Height 7.9 cm (3.1 in.)nnOrigin: North AmericannProduct of Bone ClonesnPlease be advised that this product is made to order and will require additional lead time.
