Description of life cycle and mating behavior Viviparous, placental (Ref. 50449), with 1 to 5 young per litter (Ref. 244); usually 2 or 3 pups after a gestation period of > 5 months (Ref.58048). Size at birth 52-60 cm TL (Ref. 9997). Distinct pairing with embrace (Ref. 205). During courtship and prior to copulation, the male bites the female on her right pectoral fin and uses his medially flexed right clasper in copulation (Ref. 49562, 51119). During copulation which lasts from 15 seconds to 4 minutes (Ref. 49562, 51119), both heads of the male and female are slammed in the substrate and their bodies undulate to keep their tails elevated (Ref. 51155). This mating behavior was observed in individuals bred in captivity.
