All sea stars are an echinoderm. 'Echinno' comes from spine or spiny and 'derm' means skin. They all have at least rough skin, and have a body shape which radiates from its center in a symmetrical fashion. They reproduce sexually, but one can't see the difference between the sexes. They release sperm and eggs into the water currents, as this one is doing while standing on tip-toe, where the egg and sperm gametes mix and meet.
