Brimshell Flatworm

Evolved from Brimstone Flatworm. These worms had developed a relation more intense with the sulphurant bacterias, making with that the sulphur crystals that cover its coasts formed a kind of shell with thorns. Its body became smaller and soft and it passed to dislocate for the shallow water environments in the regions with many sediments, becoming the water muddy, where it finds much food.
