Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Σπόνδυλοι: 150. Body extremely elongated, eel-like and roundish. No fins except a thin rayless finfold near and around the tip of the tail. No externally visible eyes. The lateral line system is distinct and continues to near the tip of the tail. Anus in anterior half of the body. Whitish coloration in the skin.
Facultative air-breathing (Ref. 126274); Adults occur in subterranean systems (uniquely adapted to life in dark caverns and fissures). Inhabit dark subterranean waters beneath coastal limestone, occasionally sighted in wells. Burrow into soft bottom sediments. Water is brackish and under tidal influence. Can adapt to living in a lightless environment (Ref. 44894). Are carnivores feeding on invertebrates, egg layer and prefer the following aquarium conditions: pH=7.8, H=15, 25°C water temperature, salinity 1-8 ppt; rocky substrate (note that this is not a species recommended for beginning aquarists, Ref. 6398, 44894). The male guards and builds nest or burrow (Ref. 205).
