I'm wondering if it might be easier to try adding whales. They tend to swim without moving too much, so you might get away without doing any articulation of the 3D model, and you could have them just break the surface rather than jump out. I'd love to see the occasional school of whales in the game. Later, if it was possible to add the whale's water spout when it breached and if their sounds could be heard underwater, that would rule!

Of course, if dolphins can be done, that would be great too. Anything to add character to the game. I love the seagulls around land and the crowds on land. Some activity at sea would be great, as long as it was done subtly.
