📖 Overview

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 .
