Looks like a tiny long spike urchin to me, notorious for moving corals and eating coraline. Personal I like them but when they get big they are a PITA.

Black pencil urchin is what it looks like to me. Eucidaris tribuloides
Or try looking up. Echinometra sp.

It kind of looks like a rock boring urchin to me, but it's hard to tell in that light. Is it uniformly black in real life or does it have any colour to it?

Did you eat too much of those popcorn tony? :lol:

It's 100% black






Yes I had a lot of those!
