It's a type of Echinoderm. maybe a close relative of Tripneustes gratilla? they look oddly similar (to me anyway).
Tropical island shore line, somewhere that water resides during low tide.

I do believe the first photo shows a different species from the other two. The two are most likely the Rock-boring Urchin (Echinometra mathaei). Here's my spotting of that species: http://www.projectnoah.org/spottings/802...
nice series! Sea urchins are interesting.
