Are echinoderms the same kind of animals as sea anemones and sea slugs?
Some sea anemones (related to corals and jellyfish) and the sea slugs (related to snails) may look like wannabe echinoderms, but their appearance is deceiving. Echinoderms are more closely related to us (vertebrates) than to most other animals, since we both belong to the same ancient branch of life.
