Metamorphosis. is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell . Metamorphosis. Insects are Everywhere. Look around you.. Chances are, there is an insect nearby.. Metamorphosis. As you have learned previously, insects go through a life cycle.. Complete Metamorpho. Hereditary and Reproduction. Meghann Bryant. Is the development after hatching of insects or animals from an immature stage to an adult stage. Insects can go through complete metamorphosis or incomplete metamorphosis depending on the species of insect. . An invertebrate with a soft unsegmented body often protected by a hard outer shell. Open Circulatory System. Circulatory system in which the heart pumps blood into open spaces in the body . Gill. An organ that removes oxygen from water. Centipedes, millipedes, and Insects. Centipedes. -Class . Chilopoda. (centipedes) land forms with somewhat flattened bodies that may contain from a few to 177 segments. Each segment, except the one behind the head and the last two in the body, bears a pair of jointed legs. Appendages of the first body segment are modified to form poison claws. The last pair of legs is longer than the others and serve a sensory function. There are a pair of antennae, a pair of mandibles, one or two pairs of maxillae, and a pair of eyes on the dorsal side of the head. They are carnivores and feed on cockroaches, and other insects and earthworms. They kill their prey with their poison claws and chew it with their mandibles. There are 3,000 species worldwide.
