Mantises are an order of insects that contain over 2,400 species. The largest family is the Mantidae ("mantids"). Mantises have triangular heads with bulging eyes supported on flexible necks. Their elongated bodies may or may not have wings, but all Mantodea have forelegs that are greatly enlarged and adapted for catching and gripping prey; their upright posture, while remaining stationary with forearms folded, has led to the common name praying mantis.
Mantids can turn their heads 180 degrees to scan their surroundings with two large compound eyes.
