Dragonflies and damselflies have a specially modified extensible mouthpart used to grasp their prey.  The mouthpart can shoot out rapidly to grab small invertebrates, fish, tadpoles and other small aquatic organisms.  Use the mouse to point to the mouthpart in the images of the damselfly below and find out what the name of the mouthpart is.  Be sure to locate it in both its retracted and extended state.
