They have evolved in to highly efficient hunters; their freely moveable heads sport huge compound eyes — in the case of the dragonfly, the eyes nearly cover the entire head.

Their sharp biting mouthparts, coupled with their four powerful, independent wings make them extremely agile flyers capable of snatching prey in midair.
