The mouth in these organisms is terminal and is surrounded by lips bearing sense organ. The. Incomplete metamorphosis has 3 distinct stages: egg, nymph, and adult. These systems are more primitive and exist in lower animal species, like jellyfish and sea sponges. We call this type complete because it has a specific start and end point. After hatching, many invertebrates pass through one or more larval stages that are different from the adult stage.
