Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Μαλακές ραχιαίες ακτίνες (συνολικά) : 70 - 79; Μαλακές εδρικές ακτίνες: 53 - 61; Σπόνδυλοι: 40 - 42. This species is characterized by the following: outer pseudoclasper wing-like with distinct knob at tip of inner face, isthmus between pseudoclaspers narrower than base of penis; broad anterior inner pseudoclasper; scale band on cheek with 1 or 2 rows on lower cheek; otolith with separate colliculi (Ref. 55786).
Found in coral reefs, but has also been caught 230 mm inside an ocean blue hole in the Exuma Cays, Bahamas. The eye is not particularly small, indicating that it is not a very specialized cave species. A 6.1 cm SL female specimen caught from San Salvador Island contained 50 immature embryos (4 mm length) and 40 eggs between 0.2-0.4 mm in diameter (Ref. 55786).
