Blind cave eel
The blind cave eel (Ophisternon candidum) is a species of fish in the family Synbranchidae. It is endemic to subterranean waters in the Cape Range, Australia. Like other cavefish such as Milyeringa (the only other vertebrates restricted to subterranean waters in Australia), the blind cave eel is entirely blind and lacks pigmentation.[2] It is listed as vulnerable under the Australian Environment Protection and Biodiversity Conservation Act 1999. Reaching a length of 40 cm (16 in), it is the longest known cavefish.[3]

Diet
Due to their habitat, little is known about the biology of this species. They feed opportunistically upon small animals such as crustaceans (shrimp and woodlice) and insects (adults and larvae), including both aquatic species and terrestrial species that have fallen into the water.[4]
