Sea Urchin

Additional images

This is a beautiful and perfect example of the sea urchin, Conulus. It shows particularly good detail of the plates that make up the test (shell), and the rows of holes through which the tubed feet extended. Sea urchins are actually formed by taking the five arms of a starfish and joining them at the tips; that is why the rows of tubed feet radiate in five sets from the top of the test.
