Rigilius Goby

Found singly or in pairs, close to their burrows, in clear water, sandy areas, with living corals and rubble, over bays and lagoons.

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.
