Sinh thái học
Biển Sống nổi và đáy; không di cư; Mức độ sâu 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).

Các tia vây lưng cứng (tổng cộng): 0; Tia cứng vây hậu môn 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.
