Google it, or go to liveaquaria's fish page and click saltwater, they have a few urchins there also. I'm no expert, just trying to help.

Edit: Probably not a pincushion, pincushions spines, don't seem like they are that long. It looks like the spines are smaller in diameter and shorter than on the urchin you have. Could be a pencil urchin, but i know their spines are stubby.

it looks to me like a sea mine .... or mine urchin but i just googled it andf it came back different so obv labelled wrong at my work.

pencils had rounded edges, pincushions have small spiness that arent enough to even pierce your skin .

i checked live aquaria, pet education and was on google for a couple hours and i couldnt find nothing.

only thing that i've found that comes close is a Echinometra mathaei. but they have to many different ones. they have a white tipped one that looks similar, but mine has black tips. that or maybe a rock boring sea urchin.
