However, porpoises require much shallower water, and they enjoy both freshwater and saltwater. While the Gulf of Mexico whale shares the gulf with other cetaceans (whales, dolphins and porpoises), including the bottlenose dolphin and sperm whale, it is the only baleen whale that makes the Gulf of Mexico its year-round home.
