Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; benthopelagic; non-migratory; depth range 90 - 1485 m (Ref. 104125), usually 200 - 500 m (Ref. 1371). Deep-water; 62°N - 18°S, 98°W - 17°W (Ref. 1371)

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Northeast Atlantic and Mediterranean Sea. A loose sort of southern limit for Caelorinchus caelorhincus caelorhincus is probably around Cape Verde; most specimens south and to the east into the Gulf of Guinea are likely to be Caelorinchus caelorhincus geronimoi (Iwamoto 1997, pers. Comm.). Northwest Atlantic: Canada (Ref. 5951).

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 48.0 cm TL male/unsexed; (Ref. 5951); common length : 30.0 cm TL male/unsexed; (Ref. 2683); max. reported age: 10 years (Ref. 58045)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0. Eyes large; snout short, moderately pointed, its anterolateral margin incompletely supported by bone. Head ridges strong but with rather fine spinules; terminal snout scute trifid, wider than long, small and blunt to large and pointed, with a terminal and two lateral arms of about equal size. Underside of the snout naked medially. Light organ large, a black naked fossa between and slightly anterior to the pelvic fin bases. Overall color is pale grayish-brown to swarthy, with a series of broad saddle marks in some; oral cavity pale to dark (Ref. 1371). Spiny fin ray of first dorsal fin with a smooth and rounded leading edge (Ref. 35388).

Biology     Glossary (e.g. epibenthic)

Found commonly in about 200-500 m. Feeds on a variety of benthic organisms, such as polychaetes, gastropods, cephalopods, numerous crustacean groups (copepods, gammarians, isopods, cumaceans, Natantia) and fish. Minimum depth range taken from Ref. 1371.

Estimates based on models

Preferred temperature (Ref. 123201): 8.6 - 19.6, mean 13.2 °C (based on 160 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00191 (0.00158 - 0.00230), b=3.15 (3.10 - 3.20), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.2 se; based on diet studies.
Generation time: 8.5 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
