Re: Looking for a NICE dust cover

I'm in Bangkok. I found a place online that makes outdoor covers for grills and furniture, and also had a heavy clear material for taxi seat covers. I had them make me a cover for my scope, and one for my flat top. Total cost about US$12. I had it made with some extra room so that it would slip on a...

Marine Gastropod (snail) Veliger

In addition to the marine bivalve veligers I posted a video of yesterday, I also captured some footage of a Gastropod -- in this case a snail. The lobed velum, used by the larva to swim and collect food, is very clear here.

Beautiful photography. What is this? Is there real motion or is it just water currents?
Synura is colonial algae. They have flagella, so are capable of motion as a colony.

Re: Unknown freshwater ciliate

We see a stiff, domed cell, with a long AZM, strong caudal cirri and no marginal cirri . It's Euplotes sp., seen from the dorsal aspect. The critter is in some distress: the contractile vacuole is distended, the caudal cirri are rather floppy, and the cell is spinning erratically. Thank you Bruce. ...

I wasn't the OP so I don't know ow the source of the protists. I responded to one portion of your question in the hopes that it might be helpful.

Collection of live round Diatoms

In Bangkok, when water levels are high in local klongs (canals) the water constantly washes over the banks onto concrete walkways, resulting in algae growth. I scraped up some of the soaking wet algae and found it riddled with diatoms. Diatoms are microscopic single-cell algae with golden-brown chlo...
