Etymology: Centroscymnus: centr[um] (L.), prickle or sharp point, referring to spines on both dorsal fins; scymnus, an ancient name for some kind of shark, derived from a Greek word meaning young animal, cub or whelp (See ETYFish); owstonii: In honor of Alan Owston (1853-1915), English businessman, yachtsman, and collector of Asian wildlife, who obtained holotype (See ETYFish).
