Unidentified Sponges; Porifera.

We have a whole bunch of interesting but unidentified sponges here. Apparently the only way to find what they really are is to do many of the things that we teach people not to do when SCUBA diving or snorkelling (ie. touching, handling and worse). So if a squirt, an ascidian or a sponge are wrongly identified or we haven’t tried, it’s for a good reason!
