Sea stars, sea urchins, and brittle stars all belong to the phylum Echinodermata, which is characterized by their radial symmetry, a water vascular system, and a calcareous endoskeleton made up of ossicles. These marine animals also exhibit regeneration capabilities, allowing them to regrow lost limbs or parts. Additionally, they all possess tube feet, which aid in locomotion and feeding, and they are primarily found in ocean habitats, often on the seafloor.

What is the scientific name for a brittle star?
Two of the best-known shallow species are the green brittle star (Ophioderma brevispina), found from Massachusetts to Brazil, and the common European brittle star (Ophiothrix fragilis).

What is the genus species name of a sea urchin?
Based on: http://en.wikipedia.org/wiki/Sea_urchin... Sea Urchins are small, spiny sea creatures of the class Echinoidea found in oceans all over the world. ...... Sea urchins are members of the phylum Echinodermata, which also includes starfish, sea cucumbers, brittle stars, and crinoids. Like other echinoderms they have fivefold symmetry (called pentamerism) and move by means of hundreds of tiny, transparent, adhesive "tube feet". ...... Within the echinoderms, sea urchins are classified as echinoids (class Echinoidea). Specifically, the term "sea urchin" refers to the "regular echinoids," which are symmetrical and globular. The ordinary phrase "sea urchin" actually includes several different taxonomic groups: the Echinoida and the Cidaroida or "slate-pencil urchins", which have very thick, blunt spines (see image at right), and others (see taxonomic box on the right). Besides sea urchins, the Echinoidea also includes three groups of "irregular" echinoids: flattened sand dollars, sea biscuits, and heart urchins. ...hope it helps!
