Mystery invert quiz

Annie, a recent student in my Galapagos marine ecology course sent me this photo of a lovely marine critter: 

Can you identify them, their habitat, and where the photo was taken?

UPDATE: There you go Annie, JP and Jez both nailed it.  The photo was indeed from a rocky shoreline on Maui, Hawaii and the species is Colobocentrotus atratus or the “shingle urchin”. See other photos of this lovely beast here.

    Colobocentrotus atratus. I am guessing the photo is from Hawaii, although the algae is throwing me off a bit…

  2. JP says:

    Habitat is wave exposed rocky shores.

  3. Jez says:

    Colobocentrotus atrata, intertidal (wave exposed), Hawaii?
