Amazingly, what started out as a frilly edge to your mouth, helping you grab tiny flecks of food, have now grown bigger, and bigger, and can grip, pull, manipulate, tear, your food.

Your rear half, which is no longer in even one shell, grows larger and stronger, and contains a substantial gut which is capable of digesting big meals.

No longer a little creature hiding in a shell, you are a hunter, although there are plenty of other creature even bigger than you now, and they will eat you if they can.

In order to become even more effective as a hunter, it could be worth developing some poison glands. Alternatively, those muscles in your rear half aren’t doing much now they don’t have to hold you into a shell. Perhaps they could help with the gripping of prey?
