Location Habitat
Can be seen very close to the coastline and coral reef edge; found from the surface to 100 ft. Inhabits shallow water close inshore on coral reefs and in the intertidal zone (reef flats), near reef drop-offs and close offshore. Also found in mangrove areas, moving in and out with the tide and even in fresh water, but not in tropical lakes and rivers far from the sea. Occurs singly or in small groups. Prefers fishes but also feeds on crustaceans, cephalopods and other mollusks (Ref. 6871). Viviparous (Ref. 50449). May become aggressive to spear fishers and has been reported to bite people wading in shallow water. Reported to cause poisoning (Ref. 4690). 2 to 4 young of 46 to 52 cm are born per litter. This species is commonly seen in public aquaria. Maximum reported weight from IGFA was 13.550 kg

Life Cycle & Mating Behavior
Viviparous, placental. Litter size 2-4 pups after an 8-9 months gestation period (up to 16 months in some localities). Size at birth ranges from 33-52 cm; 48-50 cm TL. Distinct pairing with embrace. Precopulatory and courtship involve the male closely following near the female's vent which could possibly be guided by their sense of smell
