Economic Importance and Threats
Importance:  Commercial, Dangers
(Fisheries, gamefish, aquarium.
Venomous)
Threats:  Anthropogenic
(This ray is commonly taken where heavy artisanal and small-scale commercial fisheries occur in or around coral reef habitats. Additionally, it may possibly be exploited locally for capture for the marine aquarium trade. It is at risk in many areas because of its dependence on coral reef habitats. These are under massive assault from net, dynamite and cyanide fisheries for teleosts in many places where the species occurs.)

Ecology
Habitat:  Reef Associated
