Arthropods And Echinoderms Quiz: Trivia!

Have you ever seen an arthropod or an echinoderm? An arthropod is an invertebrate organism with an exoskeleton, a segmented body, and a pair of jointed appendages. Echinoderms are recognized by the spines that project from their internal skeleton through their outer covering. In echinoderms, the exoskeletons provide protection against predators. This quiz will assist you to discover the difference between arthropods and echinoderms. All the best.
