What are an Arthropod's Main Characteristics?
There are so many species of arthropods and they all have very many characteristics in common.
There are four types of arthropods. Crustaceans, arachnids, centipedes, and millipedes. All of these four types of arthropods share characteristics! Arthropods have jointed appendages, an external skeleton, and a segmented body like an earthworm. They have two openings in their digestive system, an open circulatory system, bilateral symmetry, and most arthropods reproduce sexually. The exoskeleton is a waxy, waterproof covering that covers their whole entire body. Arthropods molt their skin repetitively throughout life. Bilateral symmetry means that arthropods only have one line of symmetry.
