The Blind Gudgeon is a small fish growing to 4.5 cm, generally white, but sometimes slightly pink in colour (Allen 1989).

This species is known to occur on the Cape Range Peninsula in the arid NW of WA (Humphreys & Feinberg 1995) and at Barrow I., to the NE of the Cape Range Peninsula, off the WA coastline (Humphreys 1999). It possibly also occurs in the lower Robe River and Fortescue River aquifers on the mainland opposite Barrow Island (G R. Allen 2000, pers. comm.).

Humphreys (1999) noted that this species has been recorded from 25 sites (an extension to the number of sites and habitats), but the known range of the species on the Cape Range peninsula has not increased since 1991. On the western coast of the Cape Range Peninsula, populations occur at Kudumurra Well, Milyering Well (Mees 1962), Five Mile Well, Homestead Well, New Yardie Well, Pilgramuna Well, Tantabiddi Well and two small sink holes south of Tantabiddi Ck (Allen 1982). In 1989 this species was also found at Javis Well (the most southerly location on the W side of the Cape Range peninsula) (Humphreys & Adams 1991) . On the eastern side of the Cape Range Peninsula the species was first found in 1963 at Kubura Well (Cawthorn 1963). In 1989 this species was also found on the eastern side of the Cape Range peninsula at Mowbowra Well. However, no specimens were found at Tantabiddi Well (Humphreys & Adams 1991). Numbers of this species found in caves vary from a few to around 100 (Humphreys 1999).

This species is known only from the underground waters which lie beneath the narrow coastal plain of the Cape Range Peninsula in WA (Allen 1982; Humphreys & Blyth 1994) in water temperatures which ranged from 27°C to 30°C in May and Aug. (Mees 1962). This species has been found in waters ranging from fresh to seawater and has been sampled from caves at water depths up to 33 m, from wells and from bores in which the water table was up to 50 m below the ground surface (Humphreys 1999). This species is one of only two vertebrate animals known from Australasia that are restricted to either caves or groundwater (the other is the blind cave eel Ophisternon candidum) (Humphreys & Blyth 1994).

In terms of small-scale movements it is known that the blind gudgeon moves widely through the water column, often hovering in mid- to surface waters (Humphreys & Blyth 1994).

This species primarily feeds opportunistically on invertebrates (terrestrial isopod crustaceans, cockroaches and ants) accidentally introduced into the aquatic system, but also feed on Stygiocaris shrimps and the aquatic larvae of terrestrial species (caddis larvae). Food items depend in part on their availability. Most of the individuals of this species inhabit areas where there are no surface wells or rockholes to access terrestrial insects as a food source. In these places, the main food items would be aquatic shrimps (Humphreys & Feinberg 1995). The gut contents of specimens collected in 1989 contained detrital matter and the remains of flies (Humphreys & Adams 1991).

The subterranean habit of this species restricts observation in life and hence very little is known about the biology (Humphreys & Feinberg 1995).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
