Possible Sponge or tunicate ID?

[clifg]

Hi all. Wondering if anybody has seen this before. Looks like a dense mat of spiderweb with orange spots. It does appear to have at least one mouth which can be seen in the center of the last picture. Oddly this is at the highest point in my tank. Thanks for any info
