Sand Bubbler crab in burrow and with the feeding sand balls, in the indo-pacific beach at Andaman beach, Langkawi, Malaysia, Asia.
Sand bubbler crabs live in burrows in the sand, where they remain during high tide. When the tide is out, they emerge on to the surface of the sand, and pass the sand through their mouthparts, eating detritus and plankton and discarding the processed sand as pellets, which cover the beach. The crabs work radially from the entrance to their burrows, which they re-enter as the tide rises and disintegrates the pellets. In each burrow, the crab waits out the high tide in a bubble of air. The material consumed by sand bubbler crabs has a very low concentration of organic matter, which is concentrated by egestion of indigestible material.
