The manticore is a legendary creature similar to the Egyptian sphinx. It has the body of a red lion, a human head with three rows of sharp teeth (like a shark), and a trumpet-like voice. Other aspects of the creature vary from story to story. It may be horned, winged, or both. The tail is that of either a dragon or a scorpion, and it may shoot poisonous spines to either paralyze or kill its victims. It devours its prey whole. It leaves no clothes, bones, or possessions of the prey behind. During the early centuries, it was often believed that when a person would go missing, it was evidence that it was caused by a manticore and that manticore were real. The creature's feet may be those of a dragon, but are most often described as the paws of a lion. Its size ranges from the size of a lion to the size of a horse. It is also mistaken as a bearded man when seen from a distance.
