About Coryphaenoides yaquinae

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.

The rough abyssal grenadier is an active benthic forager, with a diet that features a variety of seafloor fauna Squids, crustaceans, and polychaetes comprise the most consistent sources of prey for C. yaquinae, though stomach content analyses have revealed echinoderms, fish, and food scavenged from carrion.[5] The availability of these food sources varies, however, as seasonal migrations of pelagic teleosts and changes in the rate of phytodetritus affect the amount of organic matter that reaches the ocean floor.
