Just A Seal?

At first, Mallory and the rest of the crew thought the creature was just a seal. After all, seals were one of the most common animals in the area. It would not be unusual to see a seal resting on floating ice in between hunts. But something didn’t feel right about that theory. Seagulls mostly left seals alone, but the birds seemed to be harassing this creature. And, as the boat drew nearer, the animal stay put. A seal would have slipped back into the ocean. That’s when the crew realized what it was.
