That depends, obviously, on the species of Sea Urchin. All belong to the Phylum Echinodermata (along with sea stars and sea cucumbers) and to the Class Echinoidea. They are then divided into different orders, genera and species. That depends, obviously, on the species of Sea Urchin.

A sea urchin does not have a phylum but actually belongs to a group of sea creatures called phylum Echinodermata. This group includes sea stars, sea cucumbers, starfish and sea urchins

Sponges are in the group(phylum) Porifera. The phylum echinodermata are the starfish, urchins sea cucumbers, and sea lilies..
No - sea urchins are part of the echinoderm phylum, with sand dollars, starfish and sea cucumbers.
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.
Includes: Sea Stars, Sea Lillies, Sea Urchins, Sea Cucumbers, Brittle Stars
Echinoderma are a phylum of "spiky skin" sea life, such as starfish, sea urchins, and sand dollars.
No, starfish, sea urchins, sand dollars, and their ilk are echinoderms (phylum echinodermata), a different phylum from arthropoda.
Sea stars also known as starfish, are in the class Asteroidea. They belong to the phylum Echinodermata. Also in this phylum are sea urchins, sand dollars and sea cucumbers.
Echinoderms. No, echinoderms are starfish, sea urchins, and sea cumcumbers. Lobsters are part of the phylum Arthropoda.
Sea stars are in the phylum Echinodermata and the subphylum Asterozoa.
