The diamondback goby is a small fish that lives near and on the seabed. It relies on the sand for its food and shelter. When viewed from above, it is perfectly camouflaged to hide from large predators.
Its slender body is white and speckled with elongated orange spots. Occasionally it has bright blue spots on the sides of its head.
The goby burrows through the sand, searching for carrion or small invertebrates to feed on. It often takes shelter inside these burrows, especially when there is debris to provide it with greater protection.
It burrows by picking up mouthfuls of sand and sifting it through its gills in search of food particles.
The diamondback goby is classified by the IUCN as Least Concern, but it is not known if its population is stable.
