Ambygobius sphinx has been recorded from the eastern coast of Africa from Eritrea in the north to Maputo, Mozambique, in the south east to the Marshall Islands and Kiribati and south to the Great Barrier Reef and north to Japan.[1]

Ambygobius sphinx has been recorded from depths of 1–20 metres (3.3–65.6 ft) and is associated with reefs where it occurs singly or in pairs[1] It hovers just above the substrate in sandy areas with sparse seagrass where it creates a burrow which it uses as a refuge.[2] It feeds by sifting mouthfuls of sand from which it extracts crustaceans and gastropods.[1]

This species is common, it is frequently recorded and has a wide distribution. It is of minor importance in the aquarium trade. It is classed as Least Concern by the IUCN.[1]
