Mantoid

A Mantoid is a skinny insect, resembling a praying mantis, about the size of a Goblin's head. As it approaches its prey, the Mantoid may tilt its head inquisitively from side to side and rub its front legs together. The head tilting is actually an esophageal stretch as the Mantoid prepares to eat something wider than its throat. What looks like leg rubbing is actually the systematic sharpening of a thousand tiny razors, preparing them to cut through flesh like butter.
