Etymology: Chelidonichthys: Greek, chelidon, -onos = swift, as black as a swift + Greek, ichthys = fish (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; demersal; depth range 1 - 200 m (Ref. 4316), usually 75 - 150 m (Ref. 33616). Subtropical; 34°N - 43°S, 15°E - 154°W
Indo-West Pacific: Delagoa Bay, Mozambique to the Cape, South Africa; common in Australia and New Zealand and reported from Japan and Korea. Also reported from Hong Kong (Ref. 12086).
Length at first maturity / Size / Weight / Age
Maturity: Lm 23.0  range ? - ? cm
Max length : 60.0 cm TL male/unsexed; (Ref. 4316); common length : 40.0 cm TL male/unsexed; (Ref. 9258); max. published weight: 1.5 kg (Ref. 9988); max. reported age: 15 years (Ref. 9072)
Found from estuaries to edge of continental shelves over sand and sandy shell seabed (Ref. 9258). Reported to be often found in rivers (Ref. 4316). Juveniles may occur in bays (Ref. 33616). Benthic (Ref. 58302). Dorsal spine reported to be venomous (Ref. 9771). Neither anterolateral glandular grooves nor venom gland is present (Ref. 57406). Current information in the table (dangerous fish) do not match; needs verification. Excellent food fish (Ref. 9771). Utilized fresh and frozen; eaten pan-fried, broiled, microwaved and baked (Ref. 9988).
