Spinetail

The distinct secondary spine sill remains an evolutionary anomaly but it is no less fearsome in nature. The spine is able to function as the spices uniquely boasts two spines. When hunting, the Spinetail will rip out the outermost spine to impale its prey. The impalement is designed to preserve the organs of the prey, which is what the Spinetail's diet consists of exclusively. Using its smaller pair of limbs, it is able to filter out the organs from the victims body with relative ease.

Not really happy with this one, had to sorta start again because Photoshop crashed, what a buttclamp.
