Dolphin giving Birth

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.[48] The gestation period varies with species; for the small Tucuxi dolphin, this period is around 11 to 12 months,[49] while for the orca, the gestation period is around 17 months.[50] Typically dolphins give birth to a single calf, which is, unlike most other mammals, born tail first in most cases.[51] They usually become sexually active at a young age, even before reaching sexual maturity.[48] The age of sexual maturity varies by species and gender.
