Why is it important?
The position of the echinoderms, in particular, has been a matter of doubt and controversy in the studies of the vertebrate ancestors [1]. Sea-stars belong to the class Asteroidea of the phylum Echinoderma : Asterias rubens was studied. They are marine animals, also named starfishes. They possess a primitive lymphoïd organ:
