description Abyssal Grenadier Overview
The abyssal grenadier (Coryphaenoides armatus) is a deep-sea fish of the family Macrouridae, found in abyssal waters of all major ocean basins. It has been recorded at depths of up to approximately 6,000 meters, making it one of the deepest-dwelling vertebrate species. Like other grenadiers, it possesses an elongated, tapering body ending in a whip-like tail. The species is a scavenger and predator that feeds on cephalopods, crustaceans, and other fish.
help Abyssal Grenadier FAQ
How deep does the abyssal grenadier live?
Coryphaenoides armatus has been recorded from deep continental slopes and abyssal plains, with observations extending to roughly 6,000 meters. That range places it among the deepest-living fishes regularly encountered by baited cameras and deep-sea sampling gear.
What does an abyssal grenadier eat where there is no sunlight?
It is a mobile scavenger and predator that consumes carrion, crustaceans, worms, and other deep-sea animals. Baited camera systems often record grenadiers arriving at food falls on the abyssal seafloor.
Why does the abyssal grenadier have such a long tapering tail?
Like other rattails in the family Macrouridae, it has a large head and a body that narrows into a whip-like tail rather than ending in a conventional tail fin. This shape supports steady swimming close to the seafloor while the fish searches large areas for scarce food.
Is Coryphaenoides armatus found only in the Atlantic?
No. The abyssal grenadier has a broad distribution across the Atlantic, Pacific, Indian, and Southern ocean regions, making it unusually widespread for a deep-sea fish.
