Enderpiercer

Enderpiercers are unable to be categorized due to their enigmatic properties. First of all, they have no muscles or organs in their "tail", making it essentially useless to their survival; secondly, they have no specialized tissues except a digestive system and a basic neural net, both located in their "head". At first, this information confused scientists, but they figured out that it was a weapon. It's used like a spear, and when it penetrates the meat, it closes its massive tusks around its meal and swallows it. The tail-like part of the body is actually a handle, with the exposed bones acting as grips for the user. It is currently unknown who or what engineered this impressive bioweapon.
