Sperm whale
The film revolves around a young albino male Sperm whale named Samson who strongly believes the legendary tales of Moby Dick. The legends say that Moby Dick was a hero for all whales, and that he will someday return. He meets Sally, a young black-and-white female sperm whale who is orphaned after her pod is slaughtered by whalers. Samson's pod adopts Sally and she befriends Samson even though she does not believe in Moby Dick. Samson and Sally together survive certain dangers, such as killer whales, a massive oil slick, radiation poisoning, and whaling ships, which they refer to as "iron beasts." Eventually Samson and Sally fall in love with each other. Samson's mother is later killed by the whalers, greatly saddening Samson. Samson decides to leave Sally and his pod to search for Moby Dick and convince him to try to save whales from whalers and the "iron beasts." After nearly dying several times, due to humans causing water pollution, Samson finds Moby Dick in the underwater ruins of Atlantis, only to find that Moby Dick is senile, and too old to even forage for himself. Disappointed, Samson leaves to try to find his pod. During a storm, Samson encounters the whaling ship that killed his mother, now sinking at sea with the crew adrift in a dingy. The captain fires a rifle at Samson, causing him to react by striking the dingy and capsizing it, killing the whalers.
