That's the skeleton of an urchin! Believe it or not, they love eating kelp. Sea otters eat urchins, though. When they hunted sea otters into near-extinction on the BC Coast, the urchin population went out of control and ate all the kelp, which are like undersea forests - lots of plants and animals thrive in kelp beds.
Sea otters are making a comeback now, though, and people are replanting kelp beds up and down the coast. Kind of like treeplanting, except you drop a rock with a seed tied to it off the side of a boat.
