WebStep 2: Explanation for the correct answer Cephalochordates possess a notochord, dorsal hollow tubular nerve cord, pharyngeal slits, endostyle/thyroid gland, and a post-anal tail in the adult stage. As they show all the five key features of chordates. This makes Cephalochordates the most closely related to chordates. Webmost closely related to the vertebrates. ... In most vertebrates, the notochord remains only as a remnant, surrounded by a more complex, jointed skeleton. For example, the notochord is the gelatinous material of the disks between the vertebrae in ... slits are associated with muscles and nerves that allow water to be pumped through the slits.
