One of the differences is that my sample has many completely clear round structures and almost none that have duplicate defined internal structures.
Along the edge , there is evidence of them being dome shaped, even possibly spherical.
They are about 20 microns. Are eggs a possibility?

looked to be so but I was struck by how precise the arrangement of individuals was. Is this something you have seen before? Is this some colonizing species?

Identification help.

I have been collecting samples from various small beaches along Lake Ontario. One from Cherry beach , which is just south of the Toronto east core, was particularly verdant. I was just about to toss a slide when I decided to take a look at the paramoeciums that had been corralled by the advancing me...

Perhaps they should change their diet? Monty Python had a skit about an unorthodox confectioner , who offered delicacies, such as " Spring Surprise". I believe it had a similar effect on his customer's mouths, as these ciliates may be " facing".

:shock: This is most impressive. This must have taken you forever? Beautifully done. Diatoms must be one of the most beautiful natural things in existence. I would agree but mostly, they look like various forms of eyeballs , staring right back at you. Very patient and beautiful work. I have seen 7 ...

Reminds me of a pasty white , chubby, freckled kid engulfing a lime freeze pop, on the first hot day of summer........great video of it, though!

There appear to be 5 species in the sample I took from the pond's outflow. Two at least , similar to the shorter rod types in the first little clip. Those I would not exactly describe as gliding, although they do propel in that fashion sometimes. Mostly it is a jerking motion , which in certain circ...

Very difficult to go up from darkfield, with phase sometimes. One thing is, these can be really long.....many mm. Although, I say I have never seen them moving, they do exhibit a slow gliding or slipping movement. It is hard to tell, whether this is the result of motility, or the effect of agitation...

They look similar to many Chinese objectives from the 1980's but the same type of design was used later to. Some early plan objectives needed compensating eyepieces, in order to complete the flattening of the field, so eyepieces can have the letters pc, pk or plan compensating on them. I have never ...

I will try phase contrast. I've got a few different types, so something of the internal structure should show. These are small, though. I can do video but I have never uploaded video to anything, so I have to secure an account and such. I will get to that eventually.

Nice pictures. The second, is not an algae. probably Beggiatoa sliding bacteria with sulfur inclusions This particular strand is about 3 times the diameter of the of the sliding bacteria in my i.d. post , you replied to. The other thing about them is, I have never seen them move. They either rest o...

From the description in the link, it seems so. I didn't use a cable release for those pictures, so I think I shook the camera a little and the intracellular details are not too clear. I will try for some better ones, because I can't actually remember if this species does have intercellular divisions...

All Reichert transmitted light microscopes were 160mm tube length until they got into lockstep with American Optical in the mid-70's and converted to infinity. I'm pretty sure that any 160mm optics will work but the original Reichert ones were so good and they are so cheap generally on ebay that you...
