Illustrations of representing beings: protochordates (that is, ascidians and amphioxus), vertebrates. Fundamental morphology: branchial clefts, notochord and neural tube. Kind of symmetry: bilateral. Germ layers and coelom: triploblastics and coelomates. Digestive system: complete, deuterostomes. Respiratory system: branchial (in aquatic), cutaneous (in adult amphibians), pulmonary. Circulatory system: open in protochordates, closed in the vertebrates. Excretory system: diffusion and flame cells in the protochordates, kidneys in vertebrates. Nervous system: neural tube in embryos, single ganglion and in cerebral vesicle protochordates, brain in the cranium and spinal cord in the spinal column in vertebrates. Kinds of reproduction: sexual, with or with no larval phase.
