Their tissue is toxic to humans and believed to be toxic to many other animals, so they have few natural predators except perhaps for other sharks Maximum:largest caught and measured was 14 ft (4.3 m) long, but individuals 23+ ft (7+ m) long have been photographed in deep water. Reproduction: Maturity: unknown for either sex. Mode: ovoviviparity. Gestation:unknown, but possibly 2years or more The life history of the Pacific sleeper shark is unknown. Of the animals that do get sampled, none have ever been mature. Parameters such as fecundity, age at maturity and natural mortality are unknown.
