- Your colleague is studying a newly discovered organism. She is becoming increasingly convinced that the organism is an arthropod. You find that you must respectfully disagree when you note that the organism has a set of distinctly non-arthropod characteristics. The features that cause you to exclude the organism from the arthropod grouping are antennae, six legs, and mandibles. pseudocoel, closed circulatory system, and ventral heart. Malpighian tubules, ommatidia, and tagmata. jointed legs, ecdysis, and an exoskeleton. compound eyes, book lungs, and a hemocoel.arrow_forwardAfter examining the different specimens, construct a dichotomous key to the different phyla. Construct a dichotomous key to the classes of Phylum ARTHROPODODA according to observable morphological features.
