The Difference Between Sea Stars and Brittle Stars This round, specialized plate allows water to enter the water vascular system. In sea stars, it's located on the "top" (or aboral, meaning opposite of the side of the mouth). In brittle stars, it's located on the "bottom" (or oral side). But, let's be honest—it's way easier to tell them apart by looking at their arms (see above). There you have it!
