The Silky Shark is a circumtropical oceanic and coastal-pelagic species, most often found near the edge of continental and insular shelves at depths of 200 m or more in the epipelagic zone. It is often associated with islands, insular slopes and deepwater reefs preferring warmer waters (about 23'°C) although it also occurs from the surface to a depth of at least 500 m offshore (Last and Stevens 2009). Smaller sharks are often found in coastal nurseries and adults further offshore over deeper water. In pelagic habitats, the Silky Shark is often associated with drifting materials on the surface (Filmalter et al. 2013). Life history parameters of this species vary considerably among regions (Clarke et al. 2015a). The maximum size varies from 229-371 cm total length (TL) with a size at maturity from 180-230 cm TL for males and 180-246 cm TL for females (Clarke et al. 2015). Age at maturity ranges from 5-13 years for males and 6-15 years for females with maximum ages of 8-28.6 years for males and 11-35.8 years for females. The Silky Shark gives birth to live young, averaging 5-7 pups per litter with a range of 2-18 pups per litter (Clarke et al. 2015a). Size at birth ranges from 65-81 cm TL and the gestation period ranges from 9-12 months depending on location and study (Clarke et al. 2015). Anderson and Ahmed (1993) report juveniles of 56-63 cm TL captured off the Maldives. Fecundity increases with increasing size of females, and females give birth every 1-2 years (Clarke et al. 2015). In the eastern Arabian Sea, total length and age at maturity for males is 201-“223 cm (TL) and 10 years, and 224-“231 cm and 11 years for females (Varghese et al. 2016). Generation length is estimated to be 15 years based on the average age of maturity of females as 9 years old and average maximum age of 21 years old (excluding outliers). This is in close agreement with generation length of 16 years in Dulvy et al. (2008).
