وصف مختصر
الوصف الخارجي | قياسات المظهر الخارجي
الأشعة الظهرية الناعمة (المجموع): 13-17; شوكة شرجية 2; أشعه شرجية لينه: 20 - 23. Species distinguished by: cirrus on eye present, longer than eye diameter in males (and often in females) and arising from single base; supraorbital cirrus distinctly banded, up to 3 times as long as eye diameter; no bony ridges on rear half of interorbital region; head smooth anteriorly, never spiny; males without flag-like flap on base of first dorsal-fin spine; segmented dorsal-fin rays 13 to 17; total dorsal-fin elements 30 to 38; pectoral-fin rays usually 14; anal-fin rays 20 to 23; 3 obvious segmented pelvic-fin rays (third ray goes 4 or fewer times in length of longest); tip of lower jaw not projecting beyond tip of upper jaw and without fleshy projection; no stripe or series of dark blotches on head and body; one row of teeth on each palatine bone. 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; all fin rays, including caudal-fin rays, unbranched (simple). Lateral line absent. Scales absent (Ref.52855).
Found in intertidal areas in Bermuda. Occurs in deeper water from 30-110 m in USA.
