I think I must have the first kind of limpet, these haven't gotten any bigger and about 2-3mm max, quite transparent. They don't like being removed either, I think they die. At least when I took one off to inspect it, it didn't turn itself back over like a snail-snail.
I didn't realise the backswimmers were a problem till too late, and I think they ate each other as well. At one point I had 5 and all but one disappeared. I posted naively earlier that there was one swimming around with an ostracod on it's head but at that time I didn't realise it was a backswimmer, I thought it's legs were underneath. Now I know it must have caught one and was swimming about eating it.
If I can't get the bugs to grow back I will have to go trawling again, but I had sort of promised myself that I would not look like a crazy person with a fish net in the middle of the park again :roll: ... I'm sure I will be able to justify another trip soon :lol:
Charles, does the moss have those white blobs on it still? I am watching some that are growing on the glass, and on another strand of moss, odd things they are. They look like miniature cauliflowers or a roundish coral. About 2 mm around and the one that's on the moss is about twice that size. I don't think they are a hydra at all now.
Stella, I'm waiting for my library's copy of your book to arrive, I think it's been long enough by now. Did you also get a request from Auckland Uni as well?
