The Mediterranean grenadier (Coryphaenoides mediterraneus) is a species of deep-sea fish in the family Macrouridae.[3][4][5]
The Mediterranean grenadier has a measurement of up to 73 cm (29 in).[6] The head is scaled except for its gular and branchiostegal membranes; it has a blunt snout.[7][8] Its brain shows increased volume in the octavolateral area (premotor organization of body movements) and gustatory area (taste); this is unsurprising as it lives in near-total darkness and is dependent on chemosensory inputs to find prey.[9]
The Mediterranean grenadier lives in the North Atlantic Ocean, Mediterranean Sea and Gulf of Mexico; it is bathydemersal, living at depths of 1,000–4,262 m (3,281–13,983 ft).[6][10][11]
The Mediterranean grenadier feeds on small benthic invertebrates.[6] They exhibit a cycle of daily activity, because the solar cycle influences the movement of pelagic prey who move vertically during the day.[12] They are parasitised by many species of cestode worms.[13]
