Écologie
marin benthopélagique; non migrateur; profondeur 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).
