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.
Make a bracketed or indented dichotomous key for identifying and classifying the 9 major Invertebrate Phyla: Porifera Cnidaria Ctenophora Platyhelminthes Nematoda Mollusca Annelida Arthropoda Echinodermata Rules to follow in constructing a dichotomous key: Only use observable characteristics Start with major characteristics, placing organisms into two groups at each stage Use a single characteristic at a time Use contrasting characteristics at each stage i.e. 1(a) short, 1(b) tall Avoid using the same characteristics
