I found this shell in about 10 feet of water. Does anyone know what this thing is?

Urchin shell maybe?

It does look like one but the shape is quite different than a typical urchin.

Urchins can vary in form, urchins can even be flat (sand dollars) again I'm not 100% sure, but urchin would be my guess, might be a barnacle, but the rough texture makes me doubt it,

Did some searching online, it definitely an urchin. Found pics of some that had a somewhat similar pattern and texture. Common name was "sea potato"

Thanks for the help.

I think it is a Brissus unicolor.
