On the bright side, that means there's plenty of protists grazing on all these bacteria, including lots of small bacterivorous ciliates, and gliding euglenids (photo below). I really think that they look like twisted potato chips, don't you too? Diatom and dinoflagellates were common, but I saw more empty tests and frustules than living cells.

One of the highlights was a big amoeba which had really awesome cytoplasmic streaming and which moved by blebbing outwards in a way which is easier to show than to describe in words.
