Mediterranean red sea stars  Apr 14, 2023

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.
