Sea stars—often called starfish—are some of the most fascinating creatures to live in our oceans. For starters, despite their name, they aren"t fish—they belong to a group of marine invertebrates called echinoderms. Like all echinoderms, sea stars are characterized by the radial symmetry of their bodies, which usually have multiple arms extending from the central disc.
