Coryphaenoides yaquinae
Species of fish
The rough abyssal grenadier (Coryphaenoides yaquinae) is a species of deep-sea grenadier fish in the family Macrouridae. First described as a separate species in 1974, the rough abyssal grenadier was historically confused with its congener, Coryphaenoides armatus.[1] Unlike C. armatus, which has been recorded in the waters of the Atlantic, Pacific, Indian, and Southern oceans, observations of C. yaquinae have been confined exclusively to the Pacific ocean.[2] C. yaquinae tends to inhabit abyssopelagic depths between 3,400 and 5,800 meters (11,200 and 19,000 ft).[1] However, observations of C. yaquinae have been made as deep as 7,000 meters (23,000 ft) below sea level.[3]
