I purchased a piece of live rock as it had a brain coral . once I got home and rinsed it off I noticed this little critter in the middle does anyone know what this is? looks like some sort of a sponge any ideas?

[Calappidae]

Tunicate, filter feeder, basicly like a sponge in terms of care and all.
