Gastrotrich + ?
16x, about 40µm at its widest point and 500 long, Oblique, Olympus E-p2
I have not managed to identify Mr Hungry, seemed to have very fine cilia on the edges. Just about visible in opening scene on its posterior.
I apologize for the smudges. On the hunt for them now.

Really great video and wonderful opportunity to observe. Bad day for the gastrotrich.

Re: Gastrotrich + ?
Great catch and beautiful image. I was amazed how fast the poor guy got swallowed up. I think this looks like a flatworm [?]. Excellent video!
Re: Gastrotrich + ?
Many thanks gekko.
You can see the cilia if you really try. Now that I think about it I should have made a special effort to try and capture that characteristic.
However locomotion is clearly by cilia movement - effortless.

Agree. A little frightening.I was amazed how fast the poor guy got swallowed up.

Re: Gastrotrich + ?
My mistake. I thought flatworms undulated (if that is the word) A sort of wavy motion.

Re: Gastrotrich + ?
Larger marine flatworms do move by waving, but the smaller ones move with uniform cilia, in contrast to other worms like oligochaetes and nematodes. Here the partial division into zooids, little sensory pits behind the front with no eyespots, and shape of the pharynx look typical of Stenostomum. Which is interesting timing, seeing as zzffnn has just had the video here determined by an expert to be a species of Stenostomum too; you can compare the diagrams there.
Re: Gastrotrich + ?
Hi actinophrys,
thanks for the ID. Subsequently found this link on a Stenostomum search.
A taxonomic revision of South American species of the genus Stenostomum O. Schmidt (Platyhelminthes: Catenulida) based on morphological characters

Please note that is downloadable. It is also a coincidence that I am in South America.
Made another video (having kept the slide in a slide mailer overnight), this time in Phase, hoping to better distinguish the cilia.
Quote from page 2 of A taxonomic revision ...
:
Epidermal cilia and rhabdites: A simple ciliated epithelium homogeneously lines the body surface. Apart from this uniform cover, several species have longer conspicuous cilia (heterogeneous ciliation).
This is a screen shot that I processed in Photoshop as the bristles were not as visible as I had hoped on youtube.

Re: Gastrotrich + ?
Wow amazing video! So what happened or happens to the specimen once you are finished viewing?
I generally wash them back into the sample vessel.

Re: Gastrotrich + ?
Thanks einman
In this case though, the slide is back in the slide mailer. Will be having another session soon.
I tend to put them back, well those that do not miss the sample jar as I pour water on the the slide as I hold it over the jar. Need more hands.So what happened or happens to the specimen once you are finished viewing?

Hey 75,
Late to the party on these, for whatever reason my phone doesn't like the Video format, so I need to view them in a desktop - anyway...
These are outstanding videos! I was surprised and amazed at the capture segment, I could almost hear the theme from "Jaws" playing.
What quickness was displayed! And how quickly the victim seemed to disappear inside. Really interesting glimpse in to behavior.
And technically excellent as well. I know how hard it can be, and you did very well.
Thanks for posting these.
