Armorpig

From 2speccers2tools wiki

The armorpig is a speecies of Legopig which has adapted to eat more detritus. its lip flagella have fused into one structure much like the cilia on a comb jelly. its legs have also become shorter and it has gained a chitin plate on its back. it has gained a valve that separates its mouth from its stomach and it has gained a pair of anuses (which remove twice the waste as a regular anus). it has replaced its ancestor.
