Re: The very weirdest thing I've yet seen

It's rather odd that most of the water bears I found were in fact dormant. I've only seen a few that were moving. I've been wondering about that. Actually it's been the same with rotifers I've found, very few moving, and the great majority dormant. I've no idea why. How / where do you store your sa...

Re: The very weirdest thing I've yet seen

evaporation starts immediately, especially with well prepared thin samples, where there is little or no convex meniscus outside then cover slip perimeter. 3 things will help slow it down 1) using larger coverslips. the little 20 x 20mm ones commonly sold are difficult with samples based on water. U...

Re: The very weirdest thing I've yet seen

Could there be some kind of contaminant in the vessels you're using to collect your samples? Maybe some residual detergent or chlorinated water? Just a thought. I've been curious since your started posting your photos of water bears (which are very nice by the way!). I haven't seen a *lot* of them,...

Re: The very weirdest thing I've yet seen

Adding water, keeps the dissolved solids in the sample at a reasonably constant level, so the pressure inside the cell remains relatively constant and the organism doesn't go into a frantic search for a less hostile environment. Einman, yes the salt content would increase and eventually slow things...

Re: The very weirdest thing I've yet seen

I have seen it as well. Your question regarding the behavior of the vacuole is apt. Cytolysis is the result of a hypotonic environment resulting in water entering the cell. However, as the water evaporates on a slide you would expect to get a hypertonic situation where the dissolved salts etc in th...

Nice photos. Strange, for me, ciliate. Its "flexibility" and shape remind (a little) of Loxophyllum meleagris.

Re: Can anyone tell me what this is?

This is an egg, and you can see the beginnings of segments inside, which are characteristic of arthropods like insects. I don't have the expertise to say exactly which kind, but for instance you can find pictures of midge eggs (though usually in masses) that look much like this, complete with the o...

I was scanning through a slide during a rather boring morning at the scope when I came upon the very weirdest thing I've yet seen on my scope.

The first image is indeed a copepod, and in particular a nauplius larva, an early stage with only three pairs of appendages. The desmids are Closterium . The statoblast is from a plumatellid – these are their resting stages, much like asexual eggs, with the little polygons around the outside acting...

Several nice finds, thanks for sharing them with us. Next time you find one of those desmids, look closely at the tips... often you can see small droplets of oil dancing in them. Some of your images show these droplets, perhaps you didn't notice them. These desmids are rather large, perhaps some we...

Good haul. :) The "whopper" is an amphipod, the "water flea" is another copepod. The "space alien" is, indeed, a rotifer (a brachionid, I think...not sure, I usually ignore rotifers ;) ). Yes Bruce I was thinking copepod for the water flea too because of it's tail. Amphipod is a class of animal I'v...

It turns out to be quite different fauna than what I've found near my house and in the other gated community, or at the lake at RSW. After recovering sufficiently from yesterday's shift ...
