Tamaño / Peso / Edad
Madurez: Lm ?  range ? - ? cm
Max length : 33.5 cm FL macho / no sexado; (Ref. 107958); common length : 25.0 cm TL macho / no sexado; (Ref. 9813); peso máximo publicado: 824.00 g (Ref. 107958)
Espinas dorsales (total) : 13; Radios blandos dorsales (total) : 10; Espinas anales: 7; Radios blandos anales: 9; Vértebra: 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).
Body shape (shape guide): short and / or deep; Cross section: compressed.
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).
