This pelagic species is found on shallow reefs and deep reefs to the shelf-edge (Feitoza et al. 2005). Juveniles school in shallow waters over sandy, weedy bottoms and in mangroves. Young barracuda will spend their first summer in shallow nursery areas and move offshore to deeper water in late fall. In the second summer, young enter mangrove habitat or deeper weed beds. In its third year, it enters coral reef habitat (de Sylva 1963). Larger adults (>65cm standard length) are usually solitary and found over reef areas and offshore waters. Large schools have been observed and are probably associated with spawning behavior. Its maximum length is 200 cm (Robins and Ray 1986). It feeds mainly on littoral schooling and coral reef fishes, cephalopods, and shrimps (de Sylva 1981, Cervigon 1993). It can reach at least 14 years of age. Males mature by year three, and females by year four. Off Abu Dhabi, the mean age and size at sexual maturity for males was 1.3 years and 56.2 cm and 2.6 years and 80.1 cm for females (Grandcourt et al. 2012). When applying an age at first reproduction of 2.5 years and longevity of 14 years, its estimated generation length is 8.25 years based on the following equation recommended by the IUCN Red List methods: Age at first reproduction + (Age at last reproduction -“ age at first reproduction)/2.
