The Tiger Shark inhabits reef and slope habitats, is sometimes associated with coral reefs, and occasionally makes longer-distance excursions into the pelagic zone. It regularly dives to depths greater than 1000 m and has been noted to move hundreds to thousands of kilometres (Holmes et al. 2014, Werry et al. 2014). It attains a maximum size of at least 550 cm total length (TL). In the north-west Hawaiian Islands, Tiger Sharks with a precaudal length of 200 cm were estimated to be about five years old and one of 300 cm was about 15 years old (De Crosta et al. 1984). Branstetter et al. (1987) estimated that initial growth was very fast, but that the rate of growth of very large animals is 5-10 cm year^-1; thus, individuals of 400-450 cm TL would be 20-25 years of age. Branstetter et al. (1987) reported a maximum age of 45-50 years. Smith et al. (1998) estimated the intrinsic rate of increase of a tiger shark population at MSY to be 0.043 year^-1. Randall (1992) summarised that the size at maturity of males is 226-290 cm TL and females 250-350 cm TL.The Tiger Shark is the only species in the Carcharhinidae family that is lecithotrophic viviparous. Litter sizes are large, with between 10-82 embryos reported from a single female. Mean litter sizes of 30-35 have been reported (Tester 1969, Bass et al. 1975, Simpfendorfer 1992). The size at birth is 51-90 cm TL (Randall 1992, Simpfendorfer 1992). Clark and von Schmidt (1965) reported the gestation period as 13-16 months. There have been few other estimates of gestation period. Mating is reported to take place in the Northern Hemisphere in spring, with pupping the following spring to summer. Mating occurs before full-term females have given birth to young, indicating that litters are produced every two years or less. Based on data from the North West Atlantic, generation length is estimated at 17.5 years (Natanson et al. 1999).
