Its the Aristotle's lantern of a sea urchin, the mouth parts. Probably from Tripneuestes gratilla.
Judy's friend RCB.
Aristotle's lantern?
It's the feeding apparatus of the sea urchin - "aristitle's lantern" - found on the underside of the urchin when alive you'll only ever see the concentric teeth which open and close as they graze seaweeds of the rocks! :)
Don't know what it is but I'm showing the kids and asking. It looks cool!
It is aristotle's lantern(chewing organ)from an urchin.
Aristotle's Lantern, the chewing organ of an urchin. On www.eb.com they explain it as: "The mouth, on the underside of the body, has a complex dental apparatus called Aristotle’s lantern, which also may be venomous. The teeth of Aristotle’s lantern are typically extruded to scrape algae and other food from rocks..."

Is this a star corallite?
It is a sand dollar.

Phil thinks it is a sea urchin. Whatever it is I'm going to show the kids. They'll think it's cool.

I love that so many people came over and guessed... and most were correct! Thanks and way to go! Those who posted the Aristotle's Lantern of a sea urchin nailed it! Looks Like RCB was the first. I'm hoping to write up a post on this thing soon - or perhaps enlist someone else to - hint, hint - any takers?

Can I just say how much I love it that RCB was so quick on the draw?
Tripneuestaes gratilla sounds like an elaborate dish from the mountainous regions of Mexico.
Or one of the Royal Wedding hats...

I believe it to be an aristotle's lantern because it has the 5 connected jaws & ossicles.
