Sand Bubbler Crabs are tiny crabs who live in burrows on the beach.
They can only eat at low tide and the stuff they eat is microscopic, so they have to get to work fast.
They shovel sand into their mouth, filter out the bits of food, and throw aside the rest as a bubbly pellet.
Their fine work is destroyed when the tide comes in, but until then the work of numerous Sand Bubblers is a sight to behold!
