The hollowsnout grenadier (Coelorinchus caelorhincus), also called the blackspot grenadier,[3] is a species of fish in the family Macrouridae.[4][5][6][7]

The specific name derives from Greek κοῖλος (koilos, "hollow") and ῥύγχος (rhynchos, "snout").[8]

Description

Closeup of head

The hollowsnout grenadier is silvery in color. It is up to 48 cm (1.57 ft) in length.[9]

Habitat and Human Interaction

The hollowsnout grenadier lives in the Atlantic Ocean and Mediterranean Sea;[10] it is benthopelagic, living at depths of 90–1,485 m (295–4,872 ft).[11][9][12][13][14] Coelorinchus caelorhincus population distribution shows larger individuals normally disperse in deeper water, and younger fry populate shallower water. The species has been documented as an abundant by-catch by deep-sea trawling for both shrimp and lobster and is generally not considered for human consumption.[15]

Feeding Behaviour

The hollowsnout grenadier feeds on various marine invertebrates and vertebrates. They primarily target benthic crustaceans, (specifically amphipods, isopods, tanaids) and polychaetes, but will still hunt teleost fish and certain cephalopod species. It has been shown that C. caelorhincus will change its feeding behavior seasonally, and will rarely target more intimidating prey such as certain fish and cephalopods in colder climates.[15]
