Etymology: Chelidonichthys: Greek, chelidon, -onos = swift, as black as a swift + Greek, ichthys = fish (Ref. 45335).
More on author: Bonnaterre.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 10 - 150 m (Ref. 3687), usually ? - 40 m (Ref. 12382). Subtropical; 61°N - 35°S, 32°W - 38°E
Eastern Atlantic: Norway continuously south around Cape of Good Hope to Mozambique. Heemstra 1982 recognizes two valid subspecies, Chelidonichthys lastoviza lastoviza which ranges south to Angola and Chelidonichthys lastoviza africana occurring in South Africa (Ref. 4316).
