Does anyone know what kind of urchin this is? Is it reef safe?

long spin. I had one and It liked to each my chalice. They get big and they dont discriminated on what they decide to chew on so beware

Definite can't be trusted and does get very big over time The one I had used to leave big white patches on my Montipora plates.
