"Growth" on Live Rock

[JusMeJim]

I hope this is the right place to post this. This is on some new live rock that I received last Tuesday (8 days ago). I didn't think much about it until I looked closer tonight and noticed the "texture" of it. The rock that it's on is about 7 inches. The "growth" is about 1" and is about 1/2" to 3/4" tall.

Looks like some sponge.

Looks like some sponge.

This came in on live rock from Gulf Live Rock. Their rock isn't fully submerged, but just wrapped in soaked paper towels, so wasn't sure if a sponge would of survived being out of water??

Yes, it will live a long time out of water.
