Echinoderm larvae are common in the zooplankton. They all start their larval development as the spherical gastrula (center). Then each group of echinoderms forms a distinct larva that does not resemble the adult form at all. The left larva will become a sea urchin, the right larva will become a starfish!

Find out more about them in the Gallery of Echinoderms.
