This crab burrows into the sand and feeds on the infaunal invertebrates. Its elongated body enable it to quickly burrow into the sand. The stout antennae (missing in photograph) are used to maintain a respiratory tube to the surface to allow oxygenated water to reach the crab. This crab inhabits the the lower shore and shallow sublittoral zone in sandy areas.
