Deuterostomes like tunicates and urchins are amazing creatures that are classified together because they share aspects of their evolutionary pasts. In this lesson you'll identify these characteristics and see what makes this group of animals unique.hordates. As mentioned before, because of their similar embryonic development, chordates and echinoderms can be classified together. But unlike echinoderms, chordates do not become radially symmetric as adults, and they don't have endoskeletons or water vascular systems.
