Appearance Summary: Echinodermatasea have a hard, spiny outer skeleton made of calcium carbonate plates. They have a five-part radial symmetry and a water vascular system that helps them move. They have tube feet that are used for locomotion, feeding, and respiration. They have a unique endoskeleton made of ossicles and a complex digestive system. They also have a unique water-based respiratory system. They have a unique larval stage called the bipinnaria. They are also unique in that they have a unique form of asexual reproduction called fission.
What are the distinct features of Echinoderms? Spiny skin, bilaterally symmetrical, no vocalizations, slow-moving, bottom-dwelling, five-part radial symmetry, tube feet, water vascular system, calcified endoskeleton, carnivorous, scavenging, filter-feeding
What makes them unique?
Echinoderms body color description: Orange, Red, Purple, Brown, and White
skin type: The Echinodermatasea has a rough, spiny exterior with a bumpy, leathery texture. Its skin is covered in small, sharp spikes and is often covered in a thin layer of slime.
