Sea urchins

I found this sea urchin on the underside of a rock. It was quite big, about 10 cm in diameter.

I found this when I was beachcombing. This one is not that big, maybe 5 or 6 cm in diameter.

Another find while I was beachcombing. This is the test or skeletal shell that was washed ashore after the sea urchin died. Several spines still stuck to the test.

I found this one when I visited the Yallingup Lagoon. This one is just a few cm in diameter.
