The blind cave eel (Ophisternon candidum) is a species of fish in the Synbranchidae family. It is endemic to subterranean waters in the Cape Range, Australia. Like other cave adapted animals such as Milyeringa (the only other vertebrates restricted to subterranean waters in Australia), the blind cave eel is entirely blind and lacks pigmentation. 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.

Synbranchidae[edit]

The Synbranchidae family is largely found in tropical and subtropical regions. They are usually freshwater inhabitants, but have adapted to live in briny and estuary waters. The same species has also been found in swamp and marsh environments where they display amphibious and burrowing behaviours. Many of the species are capable of aerial respiration.[1]

Ophisternon is found in Australasia, Indo-Malaysia, West Africa and some islands of the Caribbean.

Diet[edit]

Due to their habitat, very little is known about the biology of this species. However, they have been identified as nocturnal feeders that feed opportunistically upon detritus, algae, and animals that fall into the water (e.g., insects).[2]
