Imagine being able to grow back your hand if you ever lost it — that’s exactly what starfish can do, and that’s just one of the superpowers you’ll learn about. We explore why echinoderms are called “spiny-skinned” animals, how they slowly crawl on the ocean floor using tube feet, and how their incredible water vascular system helps them move, breathe, and even eat prey larger than their mouths. You’ll also understand how their symmetry changes as they grow, how they survive without a heart or brain, and how some species can reproduce through fragmentation — forming a whole new creature from just one arm!
