Résumé
Large mature male Physeter macrocephalus reached a peak abundance of 2-3% of the population in April-May, and were very scarce in January, February and June. Measurements and observations of calves suggest that these sperm whales may generally give birth in June and July. A gestation period of c14 months is suggested. -from Author
