Etymology: Chelidonichthys: Greek, chelidon, -onos = swift, as black as a swift + Greek, ichthys = fish (Ref. 45335).
Environment / Climate / Range
Marine; demersal; depth range 10 - 390 m (Ref. 4316). Subtropical, preferred 21°C (Ref. 107945); 17°S - 45°S
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).
Length at first maturity / Size / Weight / Age
Maturity: Lm 32.8, range 27 - 35 cm
Max length : 75.0 cm TL male/unsexed; (Ref. 3699); common length : 35.0 cm TL male/unsexed; (Ref. 3699); max. reported age: 16 years (Ref. 26321)
Morphology | Morphometrics
Found over sandy and muddy bottoms in coastal areas. Feeds on fishes (Ref. 4316) and crustaceans (Ref. 5213). Excellent food fish (Ref. 4316).
