Lobed Bryozoan

Lobed Bryozoan

Observation - Lobed Bryozoan. Description: Undoubtably sponge-like; structurally and texturally just what we might expect.

Undoubtably sponge-like; structurally and texturally just what we might expect. But there is little web-evidence (less in the books) for it encrusting algal fronds, as in my previous observation http://www.ispot.org.uk/node/366005 and Jo's, still unresolved, one here http://www.ispot.org.uk/node/369738
But there is some reasonable evidence here -

Whilst investigating its structure, via my newly acquired binoscope, I discovered 'hydroids' and Aufwuchs (see http://www.ispot.org.uk/node/371188).
So, a couple of pictures of interest to the precious few marine invertebrate watchers. In due course I will (try to) separate out the true hydroids from the apparent bryozoan cells (sea mat?) and the wonderfully named Aufwuchs.

The Sponge-like encrustation is the subject of this post!
