Actinopterygii (ray-finned fishes) > Lophiiformes
(Anglerfishes) > Caulophrynidae
Etymology: Caulophryne: Greek, 'kaulos' or 'caulis' = stem + Greek, 'phryne' = toad (according to Goode and Bean (1896): "a 'phryne'-like fish with the cephalic tentacle supported on a stemlike base") ( Ref. 86949)..
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 900 - 1250 m (Ref. 58302). Deep-water
Eastern Atlantic: a single female with a parasitic male recorded from northeast of the Azores (Ref. 13584) and one record east of Cape Verde; reported from Iceland (Ref. 12462) and Namibia (Ref. 27121). Also known from the northwest Atlantic and Indo-Pacific.
