Ussal Crabs (Earth-4001)

Ussal Crabs were a species of crab Rahi. They could be tamed and used for battle, transportation, mining, and sport. These crabs were most notably used by Onu-Koro, usually in the Ussalry, and in Le-Metru where they were used by Le-Matoran drivers to haul cargo or passengers. Mining crabs in Onu-Wahi were sometimes seen with saws for pincers. At a later point in their lives, Ussal crabs would evolve to a larger, stronger form.
