Benefits

provided by FAO species catalogs
Interest to fisheries none at present. It is not known if this shark is being affected by the aquarium trade. Conservation Status : Its conservation status urgently needs to be assessed because part of its limited range is being impacted by expanding fisheries, including dynamite and poison fisheries that are destroying coral reefs, and possibly localized toxic pollution from riverine mining activities.
