I stayed with the Pec Sand far too long and had to go to work without me tea again! I'll be eight stone wet through at this rate!!
Earlier in the day I was at Morganhayes again for walkies, I saw one Crossbill go over, it would be a real treat to see them come down from the treetops to drink, like one lucky Backwater Birder did yesterday. I reckon I'll be tempted to carry my scope on future visits just in case. While in the woods today I collected some water from a small pool on one of the tracks that I know has been in situ for around a year now. I thought it may harbour a few microscopic goodies and it did! I'm going to bore you with some pictures of a few of them. Now that I know I can micro-digiscope them, there's going to be no end to them I'm afraid!!
This first one's another Water Flea not a Daphnia this time though. I think this one's called a Chydorus sphaericus an acid tolerant species.
Water Flea
This next one's interesting, well I think so anyway, it looks like a worm or leech but it isn't. Even though it's large enough to see with the naked eye, it's actually one cell!! A Ciliate, which is a unicellular protist ( a protist being neither plant nor animal nor fungi) This one's called Spirostomum ambiguum, one of the remarkable things about Spirostomum is the way it can contract. The organism can contract it's body to 1/4 of it's length in 6-8 millisecs which is the fastest contraction known in any living cell, apparently!

Not a worm
This one is a worm, a flatworm and also in the picture, an algae some of us may remember from A level biology, yes, it's Spirogyra!
Because Spirogyra is so intricate and beautiful here's a closer view:

A reminder of biology class, I can't remember the parts though, oh perhaps I can, one anyway, the green bit's the chloroplast.
And finally, this little green 'banana-y thing' is a Desmid called Closterium. "What's a Desmid?" I don't hear you ask! Well it's another type of algae, most are unicellular, and are divided into two compartments separated by a narrow bridge or isthmus. Desmids assume a variety of highly symmetrical and generally attractive shapes. There are more than 5000 different species, so you may be seeing a couple more...
