Siganidae (Rabbitfishes)
Etymology: Siganus: Latin, siganus = a fish, rabbit fish; by the similarity of the nose (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ecologia
marinhas associadas(os) a recifes; intervalo de profundidade 1 - 15 m (Ref. 37816). Tropical; 15°N - 15°S, 135°E - 159°W
Western Pacific: Solomon Islands, Papua New Guinea, Pohnpei, Kosrae, and Guam.
Tamanho / Peso / Idade
Maturity: Lm ? range ? - ? cm
Max length : 33.5 cm FL macho/indeterminado; (Ref. 107958); common length : 25.0 cm TL macho/indeterminado; (Ref. 9813); peso máx. publicado: 824.00 g (Ref. 107958)
Espinhos dorsais (total) : 13; Raios dorsais (total) : 10; Espinhos anais: 7; Raios anais : 9; Vértebras: 23. Body is bronze, with bluish spots on the head and anterior portion of the body. These spots join in the posterior portion to form vermiculating patterns. Preopercular angle 98°-102°; strong scales covering cheeks with 9-11 rows deep below center of orbit; midline of thorax scaled, pelvic ridges without scales. Low rim of anterior nostril bearing a minute, pointed peak posteriorly. The spines are stout, blunt and venomous. S. randalli is similar to S. vermiculatus but is spotted on the head and front of the back (Ref. 37816).
Adults inhabit coral reef areas with sand and coral rubble, down to at least 15 m. Juveniles found in mangroves (Ref. 9710). Adults occur in schools of 10 to 20 or more and feed on algae growing on compacted pavement areas (Ref. 9813).
