Morphology | Morphometrics
spines: 2. Species distinguished by: preopercular cirrus absent; nuchal cirrus absent; dorsal-fin elements consisting only of spines. Common amongst Chaenopsids: small elongate fishes; largest species about 12 cm SL, most under 5 cm SL. Head usually with cirri or fleshy flaps on anterior nostrils, eyes, and sometimes laterally on nape; gill membranes continuous with each other across posteroventral surface of head. Each jaw with canine-like or incisor-like teeth anteriorly; teeth usually also present on vomer and often on palatines (roof of mouth). Dorsal-fin spines flexible, usually outnumbering the segmented soft rays, spinous and segmented-rayed portions forming a single, continuous fin; 2 flexible spines in anal fin; pelvic fins inserted anterior to position of pectoral fins, with 1 spine not visible externally and only 2 or 3 segmented (soft) rays; all fin rays, including caudal-fin rays, unbranched (simple). Lateral line absent. Scales absent (Ref.52855).
Usually in shallow water associated with coral (Ref. 51183) but may also be found in shallow, clear water with limestone rubble (Ref. 7251).
