Red-finned blue-eye


The red-finned blue-eye is a tiny, critically endangered species of fish in the Pseudomugilidae family and the only species in its genus. The species was discovered in 1990. It is endemic to Central Queensland in Australia, where restricted to springs in Bush Heritage's Edgbaston Reserve. Here they live in shallow, slightly salty water that can vary from near freezing in the winter to in the summer. It reaches up to in length and only males have red fins.

Conservation status

It is listed as Critically Endangered on the IUCN Red List, and as Endangered under Queensland's Nature Conservation Act 1992. In September 2012, the species was placed on the International Union for Conservation of Nature list of 100 most endangered species on the planet. It was originally found in seven springs in its small range in the Edgbaston Reserve, but only survives in three of these. Another three translocated populations exists in the reserve.
They are at risk from extinction due to competition and predation by the flourishing introduced eastern mosquitofish, water extraction and habitat loss. An intensive conservation programme has been developed to save the species. The Edgbaston goby, 11 snail species, a small crustacean, a flatworm, a spider and a dragonfly are restricted to springs in the same reserve and also threatened.
