Grouped based on head parts: chelicerates and mandibulates. Body regions: head (antennae, mandibles), thorax (3 pairs of walking legs may have wings), abdomen (no appendages) Stalk-eyed flies (eyes off appendages)- male with widest eyes gets to reproduce with the female (sexual selection) Wings evolved 320 mya: secondarily lost over time by some insects. Molting enables changes in morphology = metamorphosis: each instar (larva) produces a new exoskeleton. Bio 111 alanna houston: at each molt, modification is possible. Metamorphose to adult form: incomplete metamorphosis or complete metamorphosis. Resting stage (pupa: often major habitat changes, dragonflies. No resting stage: no habitat change. Parasitic isopod (eats tongue of host and then acts as a tongue compose zooplankton" crabs, daphnia, barnacles, shrimp, crayfish, isopods . Millipedes (diplopoda: one pair per segment, carnivores, two pairs per segment, detritivores, herbivores. Appendages: abdomen no appendages, #1 (chelicerae) fangs, #2 (pedipalps) copulatory organs, pincers, #4,5,6,7 walking legs.
