Members of this group are sea stars, sea urchins, sea cucumbers and sand dollars. . Echinoderms have an internal skeleton called a endoskeleton – made of harden plates that makes the animal bumpy and irregular texture.. . Phylum . Echinodermata. , from the Greek for . spiny skin. Phylum Echinodermata –. spiney-skinned animals. includes sea stars, brittle stars, sea urchins, sand dollars, sea cucumbers, and crinoids.

Echinoderms. Spiny-skinned. Sea Star (Starfish). Green Sea Urchin. Rosy Feather Star. Echinoderms are animals with no: brain, eyes, heart, or lungs. Water-vascular system. Taxonomy. Common starfish. Echinoderms (phylum Echinodermata) include sea stars and sea urchins. Chordates (phylum Chordata) include the vertebrates. Echinoderms and chordates constitute the clade Deuterostomia. © 2011 Pearson Education, Inc.. Characteristics of Echinoderms. One of the strangest and most unusual phylum in the animal kingdom.. Echinoderms are . deuterostomes. , which is a trait they share with chordates (vertebrates). . All of the other invertebrates we learned about so far have been protostomes.. 1.
