Re: Some of the life found on just one slide
No, a regular slide with a 24x50mm coverslip -- lots of lateral room to look around.

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.

Some of the life found on just one slide
This was a pretty active slide, including 2 Lacrymaria feeding.

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...

Re: Is this the flagellate Petalomonas?
At various frames in the videos, when I look frame by frame, a flagellum comes into focus. I'll grab a screenshot when home. I was hoping to ID to at least the genus level for the BioBlitz project but I had thought I probably don't have enough detail. I had thought the ribs, along with the barrel sh...

Hydra-like Cnidarian from marine sample -- what is it?
While wandering through my marine sample (Gulf of Thailand), I came across what I first thought was Hydra, however Hydra don't live in marine environments. I'm trying to figure out what this is. Here are a few looks in a video, and also a quick image stack of the tentacles. mUBx3-CAxv4 hydra stack 3...

Re: Marine Foraminifera on the move
Wonderful! Those reticulopodia in the early frames look really long. Do they extend them, latch onto something and then pull themselves along? Harry The reticulopidia can be used for both feeding and locomotion. You're exactly right in your description. Between the 2 scenes in my video the Foramini...

Re: Marine Foraminifera on the move
Darkfield only at 10x. I could have seen it in phase, but was already using oil at 40x when I found this.
