Brief SummaryRead full entry
The rather small and almost T-shaped Winghead Shark has narrow, unusually long wing-like head extensions that make the head nearly half as wide as the body is long. Total body length (TL) is ~100 to 150 cm, with males apparently maturing at ~108 cm TL and females maturing by ~120 cm (males are reportedly immature at 79 cm and mature at 132 cm; pregnant females are reported from 104 to 144 cm). Young are ~32 to 50 cm TL at birth.
These poorly known sharks of the tropical Indo-west Pacific are benthopelagic (i.e., occurring near the bottom or in mid-waters) and coastal. They are found in shallow waters of the continental and insular shelves. Winghead Sharks are viviparous (live-bearing) with a yolk-sac placenta. Compagno (1984) reported brood size as 6 to 11 young (most commonly 6); Castro et al. (1999) reported brood size as 6 to 25 (mean=12). Compagno et al. (1984) inferred from circumstantial evidence that the gestation period is probably around eight months, but noted the need for confirmation; Castro et al. (1999) reported the gestation period as probably around 10 or 11 months, with an annual reproductive cycle. According to Compagno (1984), the diet of the Winghead Shark is not reported, but probably consists of small fishes, cephalopods, and crustaceans. This species is not known to attack people.
Winghead Sharks are found from the Persian Gulf to Pakistan, India, Sri Lanka, Bangladesh, Burma, Malaysia, Thailand, Vietnam, China, Taiwan, the Philippines, and Indonesia to northern Australia (Queensland and Northern Territory). They are common in the fisheries of India, Pakistan, Malaysia, and Thailand (Compagno 1984).
