Prehistoric Earth: A Natural History Wiki


The sperm whale or cachalot (Physeter macrocephalus) is the largest of the toothed whales and the largest toothed predator. It is the only living member of the genus Physeter and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia.

The sperm whale is a pelagic mammal with a worldwide range, and will migrate seasonally for feeding and breeding. Females and young males live together in groups, while mature males (bulls) live solitary lives outside of the mating season. The females cooperate to protect and nurse their young. Females give birth every four to twenty years, and care for the calves for more than a decade. A mature sperm whale has no natural predators, although calves and weakened adults are sometimes killed by pods of killer whales (orcas).

Prior to the start of the series, a pod of Sperm Whales were brought to the park. They reside in the Whale Watching Enclosure with other whales.
