I got my belly a butt on the top. They're like alive coosh ball. On a coral reef,. It's a disco. And through their feces, their poops, contribute organic material to the sediment as well. So they're pretty important just about everywhere you look in in any given environment.

The hedgehogs of the sea: echinoids are spiky, spiny, pokey, be-toothed, venomous, mysterious, gorgeous evolutionary marvels. And Dr. Rich Mooi of the California Academy of Arts & Sciences is one of their biggest champions. Come stroll through the offices for a face-to-face encounter with this infectious expert. We talk sand dollars, uni, doves of peace, fire urchins, kelp forests, tiny hats, butt placement, foot eyes and how to find your niche, even if it’s miles below the surface on a rotting log.
