Siganidae (Rabbitfishes)
Etymology: Siganus: Latin, siganus = a fish, rabbit fish; by the similarity of the nose (Ref. 45335).
Taxonomic Remarks
Cuvier in Guérin-Méneville, circa 1830.
Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino associati a barriera corallina; distribuzione batimetrica 0 - 15 m (Ref. 90102). Tropical; 20°N - 29°S, 102°E - 174°W
Western Pacific: scarcely entering the Indo-Malayan area (except eastern Indonesia), north to Palau and Kosrae, south to northwestern Australia and Tonga (Ref. 43045). Replaced by closely related Siganus virgatus from Sulawesi and the Philippines to south India (Ref. 37816).
Dimensione / Peso / Età
Maturità: Lm ? range ? - ? cm
Max length : 25.0 cm SL maschio/sesso non determinato; (Ref. 48637); common length : 20.0 cm TL maschio/sesso non determinato; (Ref. 9813)
Spine dorsali (totale) : 13; Raggi dorsali molli (totale) : 10; Spine anali: 7; Raggi anali molli: 9; Vertebre: 13. Body blue above, silvery white below; from nape through eye to chin a seal brown band, another from base of 4th-5th dorsal spines to just below of pectoral fin. Spines stout, pungent and venomous. Preopercular 97°-110°. Strong scales cover cheeks. Midline of thorax fully scaled; sometimes a few scales absent from pelvic ridges.
Body shape (shape guide): short and / or deep; Cross section: compressed.
Inhabits coral-rich areas of lagoons and seaward reefs. Juveniles form schools. Pairs form at 7 cm; but these pairs continue to form loose schools, sometimes with juvenile scarids, to feed in areas being flooded by the tide. At 20 cm, isolated pairs in deep water lagoons or on drop-offs at reef-edges feed on benthic seaweeds (Ref. 9813, 48637). Anterolateral glandular grooves with venom gland (Ref. 57406). Very closely related to the blue-spotted S. virgatus (Valenciennes) and apparently hybridizes at times with it in the Indo-Malayan region (Ref. 2334). Minimum depth reported taken from Ref. 128797.
