Comments: Lives beneath coastal limestone in perpetually dark, slightly brackish subterranean water (Ref. 44894).  Cave-dweller, lacking eyes and skin pigmentation, with well developed system of sensory papillae on the head.  Found swimming slowly or suspended near the surface of wells and sinkholes, particularly at night.  This is possibly due to the occurrence of food items, e.g., algae, small insects or invertebrates, on the water surface.  May also feed on detritus concentrated at the bottom of such openings.  May tolerate temperatures to 30°C; salinity 0.2-34 ppt.  Co-occurs with the blind eel.
