(All specimens recorded by Nevill 2017-18 were caught at the bordaz/edge of the Mahe plateau).
 


Fishery Status:

This species is not protected or subject to fishery regulations. It is caught in the hand line fishery from deep water at the edge of the Mahe Plateau, it is an uncommon to 
rare component of the catch.

Similar to E. fasciatus, differing primarily by having straighter head profile and longer snout, red rather than black tips on spinous dorsal fin. Some local fishers do not 
differentiate between the species calling both “Madanm dilo”.
