Echinoderms are generally found in shallow water near shores or in reef environments but can also live in great depths of water. Almost all echinoderms are benthic, meaning they live on the seafloor, but some sea lilies can swim for some distance while some sea cucumbers float throughout the water (Xiaofeng, Hagdorn, & Chuanshang, ). With the Arthropods, the progression of protostome animal groups hits its end. Now we go back to the deuterostome line of animals, which only has two major groups on it: our group, the chordates, which well get to soon, and the echinoderms, the starfish, sea urchins, and their relatives, a rather odd group to be our nearest relatives.
Echinoderms have a system of internal water-filled canals, which in many echinoderms form suckered "tube feet", with which the animal may move or grip objects.
