how many dolphins are born at a time
Dolphin Dolphin copulation happens belly to belly; though many species engage in lengthy foreplay, the actual act is usually brief, but may be repeated several times within a short timespan.[67] The gestation period varies with species; for the small Tucuxi dolphin, this period is around 11 to 12 months,[68] while for the orca, the gestation period is around 17 months.[69] Typically dolphins give birth to a single calf, which is, unlike most other mammals, born tail first in most cases.[70] They usually become sexually active at a young age, even before reaching sexual maturity.[67] The age of sexual maturity varies by species and gender.[71]
