walrus and seal hunters

edit:

Seals and walruses are hunted by people who live in the same environment as them (inuit, natives, etc.). They are also hunted by various whales and sharks, as well as bears.

Only if you get a specialized permit for hunting walrus, or you're a native Alaskan. In either case, you have to use the whole animal.
