Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 13 - 14; Radios blandos dorsales (total) : 10; Espinas anales: 7; Radios blandos anales: 9; Vértebra: 13. Regional variation in color exists. Anterior spines of median fins slender and pungent, posterior spines stout, all venomous including that on the nape. Preopercular angle 87-97 degrees. Anterior nostril with a long, broad flap covering posterior nostril when depressed. Variable cheek scalation. Midline of thorax devoid of scales between the pelvic ridges.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Found in small schools in very shallow water close to the bottom. Prefer hard bottoms of compacted sand with rock or coral debris. Solitary adults and groups of 3 or 4 adults have also been observed. Feed on a wide range of benthic algae. May suddenly stop and erect its fins (dorsal, anal and pelvic) presenting an encircling array of spines to potential predators; these spines are venomous. A food fish that is occasionally poisonous (Ref. 4537). Probably does not adapt well in captivity (Ref. 12382). A thermophilic species (Ref. 120766). Minimum depth from Ref. 9710.
The larvae maintain themselves near the water surface (Ref. 1419). Feeding on phytoplankton and zooplankton begins 3 days after hatching (Ref. 1419).
