A group of purple sea urchins have carved out holes for themselves in a tide pool at Yaquina Head Outstanding Natural Area in Newport, Oregon. I’m fascinated how a seemingly immobile creature that looks like a prickly cat toy could do such a thing, something I could never do, and yet they can’t remove the driftwood that the tide drops over them.
Give urchins opposable thumbs and they’d probably conquer the world.
