морской донно-пелагический; немигрирующий; пределы глубины 90 - 1485 m (Ref. 104125), usually 200 - 500 m (Ref. 1371). Deep-water; 62°N - 18°S, 98°W - 17°W (Ref. 1371)
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).

Maturity: Lm ? range ? - ? cm
Max length : 48.0 cm TL самец/пол неопределен; (Ref. 5951); common length : 30.0 cm TL самец/пол неопределен; (Ref. 2683); наибольший возраст (опубликованны данные): 10 годы (Ref. 58045)
колючие лучи спинного плавника (общее число): 0; колючие лучи анального плавника 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).
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): PD
50 = 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.
устойчивость к внешним воздействиям (Ref.
120179): низкий, минимальное время удвоения популяции 4.5-14 лет (K=0.13-0.15; tmax=8).
Fishing Vulnerability (Ref.
59153): High vulnerability (60 of 100).
