Seal

Common seal babies are born on the Arctic pack ice. Right after birth, the mother starts feeding her young with fatty milk, enabling the little seals to develop a warm fat layer. When the mother returns from hunting, she can distinguish her own pups from others by their unique smell.

You can't really 'use' a seal as they're wild animals. But if you're observing them in the Arctic, keep a safe distance to avoid scaring them or causing stress. Don't make loud noises or sudden movements. Remember, seals are protected in many areas, so it's illegal to harm or capture them. If you're on a boat, slow down when approaching them. And always respect their natural habitat, don't leave any trash behind. Just enjoy watching these amazing creatures in their natural environment.
