The status of this poorly known endemic species is of concern due to its limited distribution on coral reefs in inshore tropical waters of East Africa and Madagascar (and possibly the Seychelles and Mauritius). Occurring in areas that support heavy inshore artisanal fisheries, it is probably not a targeted species but could be overfished as bycatch. The fins of this shark are known to fetch moderate prices in Tanzania. This species is also likely to be threatened by destruction of its coral reef habitat. Although data are lacking, this species is assessed as Vulnerable due to undoubted heavy pressure from inshore fisheries and habitat destruction, both of which are likely to increase in the future. In addition, it is likely that the subpopulations occurring off East Africa and Madagascar are distinct, thus the "East African subpopulation" may also meet the threatened "B" criterion (due to restricted geographic range).
|Range Description:||The Madagascar subpopulation is likely to be distinct from the East Africa subpopulation. In addition, if this species is confirmed from Mauritius and the Seychelles, these are also likely to be distinct subpopulations. Thus further studies may reveal that the "East African subpopulation" may in fact also meet the threatened "B" criteria (due to restricted geographic range).|

|Population:||Abundant off East Africa a few decades ago (Bass, D'Aubrey and Kistnasamy, 1975a cited by Compangno 2001), but its current status is uncertain although is known to be still fairly common in catches in Tanzania.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||A little-known inshore (exact depth information is not available) benthic shark found on the continental and insular shelves. Occupies coral reefs. Possibly oviparous, but this requires confirmation (Compagno 2001). A female has been kept in captivity for over 33 years (Compagno 2001).|
Fished locally in artisanal fisheries and landed as bycatch of other fisheries. Inshore fishing pressure is heavy throughout its known range. Although it is uncertain whether the species itself is targeted, its fins are known to fetch a moderate price in Tanzania. Destruction and overfishing of this species' habitat (coral reefs). This species is amenable to captivity but its status in the aquarium trade is unknown.
The skin of this species is tough and is possibly used for leather. Amenable to captivity given its size (but status in aquarium trade is unknown). Fins are exported to the Far East and are known to fetch a moderate price. The flesh is salted and dried for local use. Jaws sold locally to tourists.
