Etymology: Emblemaria: Latin, emblema = insertion, inlaid work, raised ornament (Ref. 45335). More on authors: Ginsburg & Reid.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range - 30 m (Ref. 9710), usually - m (Ref. ). Tropical; 0°C - ; 30°N - 15°N, 98°W - 64°W
Western Central Atlantic: northeastern Gulf of Mexico in USA (Ref. 7251). Believed to have a continental distribution but has since been reported from Belize (provisional identification), Puerto Rico and the US Virgin Islands (Ref. 51183).

Morphology | Morphometrics
(total): 17 - 20;
soft rays: 20 - 21;
Vertebrae: 39 - 40. Species distinguished by: dorsal-fin spines 17 to 20; dorsal-fin rays 14 to 16; total dorsal-fin elements 30 to 38; anal-fin rays 20 or 21; vertebrae 39 or 40; pectoral-fin rays 13; 2 obvious segmented pelvic-fin rays (third ray vestigial or goes 5 or more times in length of longest); cirrus on eye arising from a single base, longer than eye diameter in males (and often in females); head smooth anteriorly, never spiny; 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 and only 2 or 3 segmented (soft) rays; all fin rays, including caudal-fin rays, unbranched (simple). Lateral line absent. Scales absent (Ref.52855).
Occurs from the shoreline to deep rocky and coral reefs (Ref. 9710).
