Corpron are always heavy, but they grow even heavier as they consume coral, rock, and metal scraps. Water pressure and the slow process of moving themselves perpetually strengthen their bodies and shells for their evolution.

When two Corpron meet in the wild, they fight for territory by bashing into each other with their steel bodies. Once it grips prey with its large pincers, it will never let go, no matter what.
