What phylum do sea urchins belong?
Echinoderms.
What types of organisms are in the phylum echinodermata?
Organisms in the phylum Echinodermata include sea stars, sea urchins, sand dollars, and sea cucumbers. These marine animals are characterized by their radial symmetry, spiny skin, and a water vascular system used for movement and feeding.
Are sponges in the group Echinodermata?
Sponges are in the group(phylum) Porifera. The phylum echinodermata are the starfish, urchins sea cucumbers, and sea lilies..
What class does a sea urchin belong to?
Sea cucumbers are part of Phylum Echinodermata along with starfish, sea urchins, sand dollars, crinoids and brittle stars..
What is Echinoderma?
Echinoderma are a phylum of "spiky skin" sea life, such as starfish, sea urchins, and sand dollars.
Are startfish arthropod?

Why are echinoderms grouped with the starfish and sea urchins?
Echinoderms are not 'grouped' with the starfish and sea urchins. Rather echinoderms are the animal phylum to which starfish and sea urchins belong to. Star fish belong to the class Asteroidea and sea urchins belong to the class Echinoidea. There are other echinoderm classes such as sea cucumbers (Holothuroidea) and brittle stars (Ophiuroidea) are two of them. All these classes fall under the Echinoderm phylum. All echinoderms share some distinguishing features: 1. Their adult bodies are arranged in five equal parts 2. They have an internal calcium carbonate skeleton 3. They have a mouth, but no head or brain (they do have a nervous system) 4. They can posses tube feet for locomotion 5. They posses a internal hydraulic system consisting of tubes of sea water to regulate the body's internal pressure and to control movement feeding and respiration.
