The Mediterranean grenadier lives in the North Atlantic Ocean, Mediterranean Sea and Gulf of Mexico; it is bathydemersal, living at depths of. During 2008–2011 baited cameras were deployed over a depth range of 532–5111 m in the Ionian Sea to characterize the large mobile fauna. At depths greater than 3000 m, including Calypso Deep, the deepest point in the Mediterranean, the Mediterranean grenadier was observed, the only one fish species found, extending this species' maximum recorded depth to 5111 m.
Behaviour
The Mediterranean grenadier feeds on small benthic invertebrates. They exhibit a cycle of dailyactivity, because the solar cycle influences the movement of pelagic prey who move vertically during the day. They are parasitised by many species of cestode worms.
