Anyone have an idea what this critter might be?

A friend said they saw it in the ocean in Lauhinia, but has no idea what it is.

They're sometimes called Shingle Urchins. That should get you and your friend on the right track.

Its something in the colobocentrotus genus, of that I'm sure. It's been 20+ years since this was my actual niche.

Many more pictures: http://echinoblog.blogspot.com/2012/06/some-colobocentrotus-diversity-aka.html

In Hawaii it is known as "kaupali" which translates as "cliff-clinging". It is found on wave-swept intertidal shores in the Indo-West Pacific, particularly on the shores of Hawaii.

Outstanding photo! Better than the ones on the websites that discuss the critter. Did your friend take it? It's a marketable image. In fact, framed prints of that would sell well, I'm very sure.
