The gestation period for pygmy sperm whales is 11 months, after which the female gives birth to a calf that is about 4 feet long. Calves are born primarily in spring and autumn.
Habitat and Distribution:
These whales strand fairly frequently, either as a single individual or in cow-calf pairs. One of the more well-known strandings to cetologists is the stranding of a whale dubbed "Inky," who came ashore in New Jersey in 1993. After vets determined there was plastic in the whale's stomach that inhibited its ability to feed, surgery was conducted and over 3 square feet of plastic, including a mylar balloon, were removed from the whale. The whale recovered from surgery and was released several months later. Initial observations suggested that she adjusted well after being returned to the wild.
The pygmy sperm whale is classified as data-deficient on the IUCN Red List, with little known about the true abundance of this species.
