Freshwater crayfish
Astacidea
The Sideways Scuttler. The small white crab is a master of the sideways shuffle, a unique movement that has fascinated cultures for centuries. This sideways walk has been seen as a symbol of the sun's indirect path across the sky, especially during solstices when the sun appears to 'crab' sideways. These crabs are equipped with powerful claws that they use to dig burrows in the sand, creating a safe haven from predators and the harsh sun. Their strategy is to use these burrows as both a home and a trap, as they can quickly retreat into them when threatened. This clever use of their environment allows them to stay safe while still being able to forage for food along the beach, making the most of their unique sideways approach.
