The rough abyssal grenadier Coryphaenoides yaquinae is a species of deep-sea grenadier fish in the family Macrouridae. They are discovered in 1974 in the Pacific ocean and can tend to inhabit abyssopelagic depths between 3,400 and 5,800 meters. Squids, crustaceans, and polychaetes comprise the most consistent sources of prey, though stomach content analyses have revealed echinoderms, fish, and food scavenged from carrion.
