Is this coral or rock?

hi all I went to my lps and I asked for rubble live rock but I got this in the mix and I was wondering if this was coral or just rock? TIA

Hard to tell really what it is......maybe some type of sponge or a type of leather maybe?

Looks like a coral skeleton. So essentially rubble rock.

Looks like it could be piece of yellow Porites. Not my image.
