Found in pairs close to their burrows over fine or silty white sand close to the intertidal zone of protected bays and harbours.
They feed on algae and tiny invertebrates by filtering sand through their mouths.
Length - 10cm
Depth - 1-10m
These Gobies feed by taking a mouthful of sand that is filtered through the gills for tiny creatures.
They make large homes on sandy areas below rocks, with a small entrance that is covered over at night, when predators are near these Gobies dive into the sand and swim through the sand to escape danger. (edit) Ref: https://www.fishbase.se/summary/55505
