I have one of these too but mine is much smaller. I couldn’t for the life me find what type of cactus it was but I think it’s a Bristle brush cactus.

I’ve attached a pic of mine for comparison. (Btw it kind of has a bald head because it had a flower stuck to it at the store and when I took the flower off some bristles came too)
