Short description
Claves de identificación | Morfología | Morfometría
Radios blandos dorsales (total) : 8 - 9; Radios blandos anales: 6 - 8; Vértebra: 27 - 31. This species is distinguished from its congeners by the following characters: head deep, depth 19-21% SL; large pelvic disc 36-39% SL, its width 30-36% SL; eye diameter large 32-40% HL; pectoral-fin rays 21-23; shallow caudal peduncle 8-10% SL, its length 10-17% SL; anus-disc distance short 6-12% SL; anus-anal fin distance long 11-15% SL; snout length long 20-33% HL; interorbital space narrow 18-29% HL (Ref. 132134).
Cross section: oval.
Occurs from an intertidal habitat down to reefs at 15 m depth. It is commonly found taking shelter in cavities used by Diadema antillarum during the day, often sharing the protection from predators offered by spines with the Vitória-Trindade Chain (VTC) endemic Hypleurochilus brasil, Apogon americanus and a number of others hosts (Ref. 132134).
