Well, sea death, I guess. My daughter caught part of a Discovery Channel special on a whale that mysteriously exploded in Taiwan, and drew her own interpretation. She calls it "The Whale Is Sad Because He Blew Up."
Note the strong use of color in the whale guts, and the attention to detail on the gas pump in the lower right - the way the gore hangs from it gives it an almost 3D feel. Also, the strong sense of emotion conveyed in the whale's eye. You really get the sense that the whale is sad because he blew up.
