Etymology: Chelidonichthys: Greek, chelidon, -onos = swift, as black as a swift + Greek, ichthys = fish (Ref. 45335).
More on author: Cuvier.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 10 - 390 m (Ref. 4316). Subtropical; 18°S - 36°S, 12°E - 36°E
Southeast Atlantic and Western Indian Ocean: Cape Fria, Namibia to Maputo, Mozambique. The record of a specimen from Reunion (MHNRUN 36) is probably erroneous (Ref. 33390).
