Description

The blind cave eel is a blind swamp eel (Synbranchidae) from underground water layers of the coastal plain of northwestern Australia. The species grows to about 40 cm and has an eel-like, almost pigmentless, pinkish-white body without pectoral fins and with strongly reduced eyes hidden under the skin. Adapted to life in total darkness it probes cave streams and aquifers for small invertebrates. Through its vulnerable groundwater habitat the species is threatened. The fish is harmless to humans.
