From Halopedia, the Halo wiki
Moon crabs are iridescent crabs that live on Myer's Moon in the Shaps system. There they can be found along the beach of a shallow sea, both in the water and out of it. Moon crabs' locomotion may be described as tiptoeing and they are known to seek out shelter when threatened.
