Explanation:
Unlike the craniates, they have no cranium, and the head is undifferentiated. Furthermore, they have no heart, but instead have pulsating blood vessels. Brusca and Brusca (2003) indicate that this group (a subphylum in their system) can be called Acrania (= without a head).

Answer:
Cephalochordate has notochord all along the body throughout life. The cephalochordates or lancelets have a long body. The body tapers or is pointed at both ends with a large notochord, that extends from head to tail.
