Arthropods have a complex life cycle, generally involving eggs, a juvenile larval stage, and the adult form, with complex metamorphoses occurring during the transitions between these stages. Some arthropods are a nutritious source of food in many parts of the world, and insects play an important role in pollination a process necessary for production in many plants. Spiders have two segments and flies have three segments. Some arthropods such as millipedes have legs on nearly every segment. This integument is important in reducing water loss in terrestrial habitats, in providing protection, and in providing a rigid skeleton against which muscles can work in order to develop motion of the animal or in its body parts. Prevents dessication Protects internal tissue Provides mechanical support Grows with the arthropod throughout its life. This periodic shedding is called molting and occurs when an arthropod splits its exoskeleton and walks out of it to later form another.

    This nonliving exoskeleton is secreted by the underlying epidermis (which corresponds to the skin of other animals). Arthropods lack locomotory cilia, even in the. Despite the remarkable variety of arthropod species, all share aspects of a single basic body plan. All arthropods possess a stiff exoskeleton (external skeleton).
