- Which of the following taxa includes myriapods that are wingless terrestrial mandibulate arthropods that are carnivorous and possess one pair of legs per body segment? Subclass Apterygota Class Diplopoda Class Chilopoda Subphylum Cheicerata Order ScorpionesWithin the subphylum Urochordata is a group called the appendicularians (or larvaceans; class Appendicularia). This relatively obscure group of organisms plays an important role in the global carbon cycle and other biogeochemical processes in the ocean. Use library and Internet resources to research the natural history of these unique invertebrate chordates. What do they eat? How do they capture food?You believe that an adult animal you are examining is a vertebrate but concede that it may be an invertebrate chordate. Which of the following would ensure that you are indeed looking at a vertebrate? OIt lacks a notochord. It has a dorsal hollow nerve cord. It uses its pharyngeal gill slits for respiration. Its notochord functions as an endoskeleton. It is able to swim.
