Unknown creature

[Duncan62]

This guy looks like some sort of sponge bit inflates and deflates like some kind of coral. These rocks were loaded with many different sponges but this creature is new to me. He is orange under any lighting.

Def colonial tunicates. If you care to get more detailed, I believe these are Ecteinascidia turbinata, or Mangrove Tunicates
