Re: Autofluorescence of plant elements
I highly recommend searching for and observing autofluorescence phenomena, just because of the amazing colors you can admire.

Re: Marine Diatom from the Gulf of Thailand, Koh Kut
Might that be a girdle view of a cenrtric diatom? You're fast approaching that point where you spend untold hours trying to identify these! It very well could be a girdle view. I shot many diatoms on an angle where it was clear that there were two centric halves of a diatom connected to each other ...

Suctorian tentacle movement
A closeup look at Suctorian tentacle movement. Suctorians have a spiral structure around their tentacles that acts like an accordian, moving the tentacles in and out.
Playback at 8x speed to better show this movement, which is very slow in real time.

Euglena sanguinea bloom
Huge bloom of Euglena sanguinea, imaged at 10x darkfield, 20x, and 40x oil.
Freshwater sample from Lumpini park, Bangkok, Thailand.
The red color is due to the presence of the carotenoid astaxanthin, an antioxidant. Astaxanthin is responsible for the pink-red color of salmon.

Re: Rotifer hatching
Sure. In the first shot you see an egg attached to a rotifer. The baby rotifer has begun breaking out of it's egg. Each successive shot shoes the baby rotifer breaking further out of it's egg., until at the end it has broken free and immediately begins feeding.

Re: Is this the flagellate Petalomonas?
We see an ovoid heterotrophic euglenoid with a strongly ribbed pellicle, but I can't make out an ingestion apparatus or any flagella. I don't see how we can rule out a strongly ribbed biflagellate, like certain species of Ploetia and Entosiphon . Is there a particular species of Petalomonas you had...
