Examples of representing beings: protochordates (ascidians, amphioxus), vertebrates. Basic morphology: notochord, branchial clefts, neural tube. Kind of symmetry: bilateral. Germ layers and coelom: triploblastics, coelomates. Digestive system: complete, deuterostomes. Respiratory system: branchial (in aquatic), cutaneous (in adult amphibians), pulmonary (others). Circulatory system: open in protochordates, closed in vertebrates. Excretory system: flame cells in protochordates and diffusion, kidneys in vertebrates. Nervous system: neural tube in embryos, cerebral vesicle and single ganglion in protochordates, brain within the spinal cord and cranium within the spinal column in vertebrates. Kind of reproduction: sexual, with or without larval stage.
