Dynamena pumila

David Kipling Heavily cropped picture of an 'ydroid fruiting body. Two ready to go and one released by the look of it. Also, guess the species ;) [OK easier in the full image, so I'm disqualifying myself].

David Kipling These fruiting bodies are very funky, I must take more pics. I thought it was some weird critter initially!

Douglas Herdson I have not looked at these for years, but could it be Dynamena pumila? Unfortunately I do not have Jo Porter's book to check. Lovely gonathecae.

Bernard Picton These structures are called corbulae (baskets). They are a modified side-branch which is folded around the gonothecae.

David Kipling Ah yes, I see - the one that is empty is clearly growing out from where a side-arm should be, there's a gap in the run. Cute!

George Brown Been a long day, just in, but how about Aglaophenia tubulifera?

Joanne Porter yes lovely gonothecae! I was teaching my classes about these today ;-)

David Kipling Full-size image now posted ;) I'm going to take more pics of these gonothecae next year, they're dead cute!
