Kina -Sea Urchin

This is the shell of a sea urchin. They look like hedgehogs on the floor of the sea.
Some people love eating them, raw. I tried it once to be brave, but do not think I would try it again. The shells are lovely when they are dried out. It is great when you find a whole one on the beach. I used to have a collection of all different sizes, but now only have this one.
