Echinodermata are named after the Greek words "echinos" meaning "spiny" and "derma" meaning "skin," referring to their characteristic spiny skin. This phylum includes marine animals such as sea stars, sea urchins, and sea cucumbers, all of which possess a calcareous endoskeleton made up of ossicles. The spiny skin and calcareous ossicles provide structural support and protection for these organisms in their aquatic environments.
