[1] Trichonotidae[7] Rhyacichthyidae Odontobutidae Milyeringidae[8] Eleotridae Butidae Thalasseleotrididae[9] Oxudercidae (Gobionellidae) Gobiidae Under this classification system the Gobiiformes is divided into the following families: The loach-gobies are a small family, with only three species split between two genera, which inhabits marine and fresh water in Oceania and the western Pacific.

It comprises two genera of marine gobies from the temperate waters of Australia and New Zealand, with a total of three species between them.

Many species have fused pelvic fins that can be used as a suction device; some island species, such as the red-tailed stream goby (Lentipes concolor), are able to use these pelvic fins to ascend rock faces alongside waterfalls, allowing them to inhabit waters far from the ocean.

[10] Some of the species that are found in fresh water as adults spawn in the ocean and are catadromous, not unlike the eels of the family Anguillidae.

With the blennies, the Gobiidae constitute a dominant part of the benthic, small fish fauna in tropical reef habitats.

They are most diverse in the tropical Indo-West Pacific but the family is well represented in temperate waters in both the northern and southern hemispheres.

They are mostly free living fishes found alone or in small schools, but some form associations with invertebrates, especially in coral reefs.

However, in the southern region of its range where waters remain at a warmer temperature, E. newberryi will reproduce year round.

The altering of streams flow with diversions has affected the salinity of the water and changed the habitat at creek mouths where E. newberryi has historically lived.

Restoration projects have been started to bring populations back to a more stable number by making more habitat available, as well as providing protective areas.
