It was found in a sample of pond water under a microscope. It was moving abound in some plant like material. It was clear on the outside and darker within.
This organism was found in a sample collected from the pond behind Louisa County High School. The organism used the extended cell membrane to move to the food source. The organism looked as if it growed and shrank as the pseud or its "false foot" propelled it forwars. It moved quickly under the microscope.
Most likely a favella
Tintinnina Without the living organism inside. This is just its "container".
Prof Wallace Marshall collected some stentor from the Golden Gate Park pond and we imaged it together with a Foldscope during a school demonstration. They seemed to be growing well in a culture from the original sample.
Later in the video (on link below) - they seemed to have contracted into a ball. The spiral row of cilia and the symbiotic green algae are evident. The swimming behavior (backing up and turning) are quiet unusual. Also visible is the row of cilia on the surface.

On my walk in the tidal zone; I noticed a fish (see microcosmos post for details on the fish). I imaged the "fin" of the live fish and found it infected with these parasites all along the fin (I released the fish after imaging). I believe they are Ambiphyra; with a beautiful ciliary band (see videos on microcosmos post for details).
It's fascinating to see a bound ciliate on a fish. For the ciliate it's a fascinating "best of both worlds". It's interesting to note that we just had a discussion on parasites (possibly vorticella) on mosquito larvae by iNat user @damontighe.

All data collected with a Foldscope (140x) on an iPhone directly in the field.
I'm guessing this is a protozoan, because its traditionally the junk drawer of taxanomy. On the segments of a mosquito larvae I'm finding all of these goblet shaped protrusions that when I viewed them in my Foldscope seemed to be helping to circulate the water column, but its had to tell because I can't see all of the hairs at once to see what they are doing
If you look at the largest image of the mosquito you can see the white fuzz around the edge of the segments and under the scope these are the goblet shaped stuctures
Video allows you to see many locations of the possible parasite along the length of the body:
and another focused shot on one cluster:
The ciliates are a group of protozoans characterized by the presence of hair-like organelles called cilia, which are identical in structure to eukaryotic flagella, but typically shorter and present in much larger numbers with a different undulating pattern than flagella. Cilia occur in all members of the group (although the peculiar Suctoria only have them for part of the life-cycle) and are variously used in swimming, crawling, attachment, feeding, and sensation.
