Porpoises

Porpoises are sea mamals that are usually recognized as a baby dolphin but it is not. The differences between a dolphin and a porpoise is a pospoise has a more dull like shaped head and and a smaller dorsal fin the side fins and the flukes. Porpoises live in all oceans but only along the coast, because porpoises are smaller so they lose more heat than other marine mammals do so they try to stay in the warmest part of the ocean In the front of the dolphins head there is a melon which produces sound that the dolphin makes. If you look genetically than porpoises are more related to a beluga (the only white whale) than to dolphins. Porpoises are not as playful like dolphins are all they do is they hunt mostly the only time you see them is when they aretaking a breath and not even for long.
