The Crabs That Make Sand Balls
We have noticed a few times already that Australian beaches are the backdrop for an amazing ritual. Some crabs (not sure if they are soldier crabs or sand bubbler crabs, sorry we do not know all about crabs), hardly visible to the eye, dig in the sand looking for microscopic food between each grain. They quickly gather the sand into a sphere and tosse it behind their legs. Eventually these small sand balls turn into spectacular sand sculptures. Nature is beautiful!
