🐟 Physical Description

Anal spines: 2. Species distinguished by: side of body with 8 dark blotches; dorsal fin consisting of spines and segmented rays; total dorsal-fin elements 44 or 45. 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 (numbering 7 to 37), 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).
