Twice a day. It never ends!

“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.” (From Wikipedia)

Thanks for commenting. These crabs are ever so tiny. And very very quick as the dart in and out of their burrows to avoid being breakfast for the seagulls. To capture them I had to put my iPhone on “live” mode (like a very very short video) and keep pointing at the sand hole and keep shooting!!

[Diane Marie]

wow
