Peter Gott Posted November 10, 2016 Share Posted November 10, 2016 Ok so after some cleaning today the big red shroom polyp closed up enough to see my most interesting mystery hitchhiker more clearly, and I have been wracking my brain trying to remember what it is to no avail, so I need y'all's help desperately. For some reason I have it in my head as being some sort of colonial tunicates, but that makes zero sense visually, and I can't find anything to support it, so I can't believe it. These cracks open and close. When they're closed the whole pink mass looks like a sponge. When they are open, there are siphon-like spots at the intersections of the cracks. They are very widely opened in these pics, I think because there is a lot of food stirred up into the water column from me cleaning the acrylic and because the mushroom polyp isn't folded over it. Whatever it is, it's definitely a filter feeder, but isn't it too mobile to be a sponge? Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

Timfish Posted November 11, 2016 Share Posted November 11, 2016 Definitely a sponge and most likely Placospongia carinata. Check image "C" in fig. 1 here: https://www.ncbi.nlm.nih.gov/pubmed/23794884 Link to comment Share on other sites More sharing options...
