The ability to utilize parts of the body as projectiles. While this ability originated from tarantulas shooting tiny stinging hairs, due to genetic mutation, the projectile strength has been heightened. An animal may dislodge and shoot quills, spikes, hairs, feathers, or otherwise at will. However, the "ammo" must grow back, and as the body works to repair itself, the animal will need to consume a larger amount of food. It is therefore unwise to use this ability when food is short.
