Etymology: Chelidonichthys: Greek, chelidon, -onos = swift, as black as a swift + Greek, ichthys = fish (Ref. 45335).
Environment / Climate / Range
Marine; demersal; depth range 20 - 318 m (Ref. 56504). Subtropical; 8°C - 24°C (Ref. 4944), preferred 9°C (Ref. 107945); 66°N - 9°N, 18°W - 42°E
Eastern Atlantic: Norway to Cape Blanc (along the African coast); not recorded at Madeira and the Azores. Also in the Mediterranean and Black seas.
Length at first maturity / Size / Weight / Age
Maturity: Lm 21.6  range ? - ? cm
Max length : 75.1 cm TL male/unsexed; (Ref. 59122); common length : 30.0 cm TL male/unsexed; (Ref. 3397); max. published weight: 6.0 kg (Ref. 3397); max. reported age: 15 years (Ref. 26811)
Longest ray in the pectoral fin reaching the front part of the anal fin. Lateral line scales smooth. Reddish color (Ref. 35388).
Occurs at temperatures ranging from 8.0-24.0 °C (Ref. 4944). Inhabits sand, muddy sand or gravel bottoms. Up to depth of 318 m in the eastern Ionian Sea (Ref. 56504). Feeds on fish, crustaceans and mollusks. Has three isolated rays on the pectoral fin which function as legs on which the fish rests and also help in locating food on the soft bottom (Ref. 9988). Marketed fresh or frozen; eaten pan-fried, broiled, microwaved or baked (Ref. 9988).
Distinct pairing during breeding (Ref. 205).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00594 - 0.00926), b=3.02 (2.96 - 3.08), based on LWR estimates for this species (Ref. 93245
Trophic Level (Ref. 69278
): 4.0 ±0.0 se; Based on diet studies.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (K=0.15-1.6(?); tmax=14; tm=3).
Prior r = 0.58, 2 SD range = 0.3 - 1.13, log(r) = -0.54, SD log(r) = 0.33, Based on: 1 M, 6 K, 2 tgen, 1 tmax, records
Vulnerability (Ref. 59153
): Moderate vulnerability (40 of 100) .
