Gestation in Sperm Whale females lasts about 14 to 16 months. A sigle calf is produced at the end of gestation. Lactation proceeds for 19 to 42 months, but calves may suckle up to 13 years. Calves can suckle from females other than their mothers. Females generally have birth intervals of three to six years between calf birth.
