Found growing on bottom side of LIVE rock

I noticed white stick like structures growing on the under side of one of my live rocks. Any ideas as to what it might be. It looks like fingers I've never bought a coral that looks like this and have had the rock for almost 2 years.

It's a type of sponge.
