That photo looks like a Polar Bear smorgasbord.

Yep - if that particular place had polar bears, it would be.
The guide told us that orcas (killer whales) were the main predators here. The seals are fine while they're on the ice ... but they get hungry. And once they slip back into the water to feed, they sometimes end up on the orca menu ... gobble gobble
