Are Brittle Stars Brittle. Compared to sea stars, brittle stars' arms and central disk are much more distinctly separated, and their arms allow them to move gracefully and purposefully in a rowing movement. Found on sea floors around the world, they are echinoderms along with sea stars (starfish), sea urchins and sea cucumbers but are different from sea stars. Despite both being marine invertebrates within the same phylum echinodermata, they have unique characteristics that make them distinct, lovable creatures of the sea. However, its anatomy shouldn’t be under estimated as basic; brittle stars (ophiurida) are echinoderms, the same family that includes sea stars (commonly called starfish), sea urchins, sand dollars, and sea cucumbers. The star is known for its bioluminescent tendencies. brittle star, any of the 2,100 living species of marine invertebrates constituting the subclass ophiuroidea (phylum echinodermata). brittle stars are sea creatures with five limbs and no brain. they look awfully similar and are closely related, but they are actually quite different. Each brittle star has a distinct central disk and five skinny, flexible arms. the brittle stars gets its name from the way its skins dries and becomes very easily broken. at first glance, sea stars and brittle stars might appear to be the same—they (usually) have five radiating arms and creep along on the ocean floor. But although sea stars and brittle stars are similar, they’re actually quite different! The central disk is made up of a skeleton of calcium carbonate and contains all the internal organs. although brittle stars and starfish are closely related, they are completely different species.
