The posidonia clingfish is Endemism, endemic to southern Australia where its range extends from Corner Inlet in Victoria State, Victoria west as far as Rottnest Island in Western Australia. It occurs down to a depth of where it is found on macroalgae and within seagrass beds, its favoured substrate to adhere to is the leaves of the sea grass ''Posidonia australis''. This species is the only known member of its genus and was Species description, described by John C.

Clingfish
Clingfishes are fishes of the family Gobiesocidae, the only family in the order Gobiesociformes. These fairly small to very small fishes are widespread in tropical and temperate regions, mostly near the coast, but a few species in deeper seas or fresh water. Most species shelter in shallow reefs or seagrass beds, clinging to rocks, algae and seagrass leaves with their sucking disc, a structure on their chest. They are generally too small to be of interest to fisheries, although the relatively large '' Sicyases sanguineus'' regularly is caught as a food fish, and some of the other species occasionally appear in the marine aquarium trade. Distribution and habitat Clingfishes are primarily found near the shore in the Atlantic, Indian and Pacific Oceans, including marginal seas such as the Mediterranean, Gulf of Mexico, Caribbean and Gulf of California. The greatest species richness is in tropical and warm temperate regions, but the range of a few extends into colder waters, lik ...
