On teaching biology: sea urchins

I stumbled upon a couple dozen of these guys this afternoon--I'd seen them before, a few years ago, and (mostly) forgot about them, but here they are, still being sea urchins, in the same spot they were being sea urchins when I was less mortal than I am today.

How do you convey that in a classroom that supposedly teaches biology?

How do you convey that anywhere?
