10-13 ft long The Skull Island Fur Seal is a light brown arctocephaline eared seal from the coast of Skull Island. There are a few beaches in the more sheltered inlets between the rocky headlands. These are the transitory homes of Skull Island fur seals and sea turtles. Rich in fat, they can be prey to sauropsid predators like Tartarusaurus andNefundusaurus. Unguarded pups can be taken by Peracerdon. The skulls of these pinnipeds can be used by Osteodomus for protective shells
