Moose are known to swim in coastal waters where orcas live, making them a potential prey target if they are vulnerable or isolated, especially in areas where their populations overlap, allowing orcas to occasionally hunt them for food
moose are like WALLS. i don't even live in an area with moose but i know that you have a better chance of pushing over an 18-wheeler cement mixer than a moose. and the fact that they SWIM (and extremely fast, at that) is horrifying to me. if an orca can kill a moose, they damn well deserve to eat it.
