With a body color same as sand, the crabs are easy to miss.
Whats unmissable however are the intricate patterns they make on the beach when they search for food.
After they have scrapped the sand grains clean, they roll them into little balls and toss them behind.
By doing this they avoid sifting the same sand twice.
The crabs come out of their burrows as soon as the tide recedes.
The more intricate the pattern of sand balls, the longer the tide has been out.
