Contractile vacuoles and radiating canals

[macnmotion]

I put together a short video showing the interplay between contractile vacuoles and radiating canals in this unknown ciliate. 40X phase contrast objective.

Wow, that's a very impressive video.
Very well done !
I like it very much !!

Very detailed an impressive video. You got some nice details of the oral cavity too. Well done!

macnmotion,

Great footage.

Thanks everyone. I'm uncertain what it is. I understood paramecia have 2 vacuoles. This has 3.

Very nice video and excellent information!

Amazing video!

A really nice, clear video! Great use of phase.

Usually, there are only 2 CVs. However, Sergei Fokin says P. multimicronucleatum sometimes has 3 CVs (and at least one species, P. ugandae has 5-7!). In any case, the critter you've recorded here is definitely a slightly compressed Paramecium.

Thanks Bruce for that info. It seems as though I'm getting very good at compressing organisms. I guess I need a softer hand.

Compression is a useful technique! While it distorts the overall shape of the critter, it often exposes details that would otherwise be invisible.

Really excellent video, both for its quality and for the information it conveys so well.
