These insects either have hemimetabolous development, and undergo an incomplete or partial metamorphosis, or holometabolous development, which undergo a complete metamorphosis, including a pupal or resting stage between the larval and adult forms. In hemimetabolous insects, immature stages are called nymphs.
Metamorphosis is a time of dramatic change. Tadpoles move around and 'swim' using their tail as a 'propeller.' During metamorphosis, they grow legs and arms, then lose their tail completely. Growafrog tadpoles have 'tentacles' that allow them to sense food, foreign objects and movements in the water.
