Size and Age Averages 2.2 - 2.7 meters. Maximum reported size is 4.5 meters, but this might be exaggerated.
- Reproduction: Ovoviviparous. Embryos develop inside an egg case in the mother's ovary, hatch, and are born live. Litters are typically 20-30 pups. Juveniles are often found in shallow coral reefs and mangroves. Lifespan under human care can reach 25 years, lifespan in the wild is unknown.
- During mating season, males will bite onto the female's pectoral fins, and will then attempt to push the female onto her side. Non receptive females may try to avoid males by burying their pectoral fins in the sand.
