Crabby Wasteland

The verdant sky shined like the northern lights. It was a wasteland, with nothing but contaminants and mutants. It's been awhile since humans went extinct, a loooong while. The land was almost... barren. They fought regularly, the mutants. The bright red carapace and claws gripping and breaking at each other's hard bodies. Shards of shell would fling viciously through the air from their ferocious battles. These... beasts - brutal as they are - were on the top of the food chain. It wasn't suprising how they turned on one another. After all, their food was gone...

(Story was written based on Proffessor Khan's amaazing example on this project, in which one crab turned on another)
