Royal Urchin/Tuxedo Urchin, same thing?

[mapster]

Its listed as a Royal Urchin on Premium Aquatics website. I just wanted to make sure its the same as a Tux. There is no scientific name listed.

From what I know, they are the same urchin(mespilla), sometimes even called a globe urchin.

If they are both Mespilia globus they are the same. If they aren't they are different. Common names are no way to compare things. I can call it one and you another, both are right, both describe the same thing and we don't know it. The reverse is also true.

Thanks guy, I looked intheir stock availability section and sure enough it was labeled Mespilia globus. I just picked one up, along with 3 more fighting conch's. Finally the fighters are in stock!

Thanks again guys
