Suckers
On Sunday I came across a pond with some Lemna minor (duckweed) and Riccia (crystalwort). Being the biologist (& fishkeeper) that I am, I scooped up a sample and took it home.
Once at home, I filled up my tiny tank and floated my newly collected specimen. When I dropped it in, there were all these teeny tiny worms (possibly flatworms of some sort) which dropped to the bottom. They were very thin and about 1 mm long. Then there were some tiny worms, perhaps nematodes or some of annelid thrashing about. Of course, there were the obligatory Daphnia and some isopods and coepepods.
I stirred it with one of my ice lolly sticks and a leech dropped out! Further disturbance made some more drop out. Anyway, here’s a vid of two of them in motion. Perhaps I’ll do some photomicroscopy later. No doubt there’ll be some algae in the sample.
