Common name: Echinoderms

Echinodermata, commonly known as echinoderms, is a phylum that includes starfish, sea urchins, sand dollars, and sea cucumbers. These marine invertebrates are known for their radial symmetry, a calcareous endoskeleton, and a water vascular system that aids in locomotion. Echinoderms are important for reef hobbyists due to their roles in the ecosystem, such as algae control and substrate aeration. Some species are popular in reef aquariums for their beauty and utility, but they require specific care to thrive.
