    What makes chordates different from non-chordates?What makes chordates different is that, in non-chordates, the nerve cords are solid and are either ventral or lateral within the body. This flexible skeletal rod that’s made of cartilage is what gives chordates their name. The notochord runs between an animal’s digestive tube and its nerve cord and provides support for the body.
    What is the circulatory system in chordates?The circulatory system in chordates has a characteristic pattern. In tunicates and vertebrates the blood is propelled by a distinct heart; in cephalochordates, by contraction of the blood vessels. Unoxygenated blood is driven forward via a vessel called the ventral aorta.
    What is the life cycle of a chordate?Reproduction and life cycle. The chordate life cycle begins with fertilization (the union of sperm and egg). In its primitive form, fertilization occurs externally, in the water. Asexual reproduction takes place in tunicates and in some vertebrates (females of some fish and lizards can reproduce without fertilization).
