Sharks don't have notochords because they are vertebrates. All vertebrates go through an embryonic stage where a notochord is present, but then during development in the womb, this structure is replaced with a spine. The remnants of a notochord in these species can be found as the nucleus pulposus, a jelly-like center of intervertebral discs.
