Skriton

Skritons, sometimes referred to as desert crabs, were a species that resided on the moon Jedha. They were very ruthless creatures and unpredictable. Skritons were very lopsided; their left claw was much bigger than the right, and they used their left claw as a weapon to pinch their opponents. Indeed, their claws could easily crush objects and prey. Their skin was also quite resistant to heavy attacks, including lightsaber strikes, particularly on their dominant left claw. They were one of the deadliest creatures on Jedha as they stalked their prey from underground then popped up at the right moment. The Jedi Cal Kestis considered them unpleasant creatures.
