Seals Sea Lions and Walrus Skulls
Shop for Seals Sea Lions and Walrus Skulls - Pinnipeds, often generalized as seals,are a widely distributed and diverse clade of fin-footed, semiaquatic marine mammals. They comprise the extant families Odobenidae whose only living member is the walrus, Otariidae, the eared seals which are the  sea lions and fur seals, and Phocidae the earless, or true seals. There are 33 extant species of pinnipeds, and more than 50 extinct species have been described from fossils. While seals were historically thought to have descended from two ancestral lines, molecular evidence supports them as a monophyletic lineage - descended from one ancestral line. Pinnipeds belong to the order Carnivora and their closest living relatives are bears and musteloids.
Seals range in size from the 1 m or 3 ft 3 in. and 45 kg or 99 lbs. They have streamlined bodies and four limbs that are modified into flippers. Though not as fast in the water as dolphins, seals are more flexible and agile. Otariids use their front limbs primarily to propel themselves through the water, while phocids and walruses use their hind limbs. Otariids and walruses have hind limbs that can be pulled under the body and used as legs on land. By comparison, terrestrial locomotion by phocids is more cumbersome. Otariids have visible external ears, while phocids and walruses lack these. Pinnipeds have well-developed senses—their eyesight and hearing are adapted for both air and water, and they have an advanced tactile system in their whiskers. Some species are well adapted for diving to great depths. They have a layer of fat, or blubber, under the skin to keep warm in the cold water, and, other than the walrus, all species are covered in fur.

The American River Otter (Lontra canadensis), also known as the Northern River Otter or the Common Otter, is a semi-aquatic mammal endemic to the North American continent found in and along its waterways and coasts. An adult River Otter can weigh between 5.0 and 14 kg (11.0 and 30.9 lbs). The River Otter is protected and insulated by a thick, water-repellent coat of fur. 

The river otter, a member of the subfamily Lutrinae in the weasel family (Mustelidae), is equally versatile in the water and on land. It establishes a burrow close to the water's edge in river, lake, swamp, coastal shoreline, tidal flat, or estuary ecosystems. The den typically has many tunnel openings, one of which generally allows the otter to enter and exit the body of water.
