Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2; Dorsal soft rays (total): 22 - 24; Anal soft rays: 20 - 22; Vertebrae: 20. Diagnosis: Extremely small size at maturity (1.5 cm SL). Prominently elevated dorsal and ventral profiles. Extremely long bristles on caudal peduncle of male, projecting posteriorly to behind middle of caudal fin. Low fin ray counts (D.22 to 24; A.20 to 22; P.10) (Ref. 35708).
Inhabits sheltered coastal habitats, usually in areas with mixed low reef and sparse seagrass (Ref. 48637).
