The Broadfin Shark (Lamiopsis temmincki) is a rare shark with a sporadic distribution off Pakistan, India, Burma, Indonesia (Makassar Straits), Sarawak, and China. It occurs on the continental shelf, mostly close inshore. The species is taken in bottom and floating gill nets and with line gear regularly (but sometimes in low numbers) by local fishermen off India (Bombay), Pakistan (Karachi), Sarawak and Kalimantan (Indonesia). Its meat is utilized for human consumption, its fins dried for the shark fin trade, and it liver is used for vitamin oil. This species apparently is rare throughout the majority of its range, but it was once known to be common off the western coast of India. No information is available to determine historical trends in other areas. It is only observed in low numbers in heavily fished areas such as Indonesia, indicating probable population depletion. This species is fairly similar to Glyphis species, which are suspected to have undergone serious declines as result of heavy fishing pressure. Given its rarity, very heavy and unregulated fishing pressure throughout its entire range, and evidence to suggest that significant declines have already occurred off India, the Broadfin Shark is assessed as Endangered globally.

|Population:||Rare throughout most of its range, but once known to be common off west coast of India (Compagno et al. 2005).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Found inshore on the continental shelf (mostly close inshore). A viviparous species giving birth to four to eight pups per litter after an eight month gestation period. Pups are 40-60 cm long when born, and grow to a maximum of 168 cm TL. Males mature at 114 cm TL, whereas females mature at <130 cm TL (Compagno et al. 2005).|
|Use and Trade:||Meat is utilized for human consumption, fins dried for fin trade and livers used for vitamin oil (Compagno in prep.).|
|Major Threat(s):||Taken regularly (but in low numbers) by local fishermen of India (Bombay), Pakistan (Karachi), Sarawak and Kalimantan (Indonesia). Taken in bottom and floating gill nets and with line gear. Meat is utilized for human consumption, fins dried for fin trade and livers used for vitamin oil (Compagno in prep.). Probably threatened by habitat removal and destruction (e.g., inshore mangrove areas) which is prolific throughout much of its range. As this species predominantly occurs inshore, pollution from river outflow is also a possible threat.|
|Conservation Actions:||Few specimens occur in museum collections and its current abundance where it was formerly reported as being common (India) needs to be investigated (Compagno in prep.).|
