Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 13; Radios blandos dorsales (total) : 13 - 15; Espinas anales: 3; Radios blandos anales: 6 - 7; Vértebra: 26. Head spines strong to moderate - nasal, preocular, postocular, tympanic and parietal spines present, nuchals usually absent, supraocular and coronal spines absent (Ref. 27437). Weak symphyseal knob; 2nd anal fin spine longer than 3rd (Ref. 27437). Caudal fin moderately indented (Ref. 6885). Pink to red with irregular dark markings interrupted by lighter band along two thirds of lateral line; caudal fin with dark membranes and pink or red band terminating fin; anal fin has black between 2nd and 3rd spines; tip of spinous dorsal black (Ref. 27437).
Body shape (shape guide): fusiform / normal.
Viviparous (Ref. 34817). Too small to be of high commercial value (Ref. 27437).
