Maximum Weight — Odontoceti

Among Odontoceti, the sperm whale is the undisputed giant, reaching up to 57,000 kg — more than 16 times the weight of a killer whale. The size diversity within this group is enormous: the dwarf sperm whale and the melon-headed whale weigh as little as 275 kg at maximum. This variation in body mass reflects adaptations to different ecological niches, diving depths, and hunting strategies.
