A GIANT CILIATE

In the same location from my last post I have spotted this giant ciliate in action. The movement of the organism is awesome. The location almost filled with rotten hydrophytes that making it a treasure trove of microorganism. After hours of observation when it gradually slowed down its movement, the ciliated frontal parts were found prominent. The organism was so flexible that it intensely changes it shapes as it pushes on the substratum. It looks like Enteroplea lacustris.

I request @ Laks sir and @Manu sir and all the expert  to identify the organism.

    Dear Raju,

    What an amazing data set – yet again. Absolutely beautiful. You indeed have a treasure trove!! Please map the locations carefully, you might stumble upon in described species at this rate!

    Enteroplea is a rotifer species – which is a multi cellular animal. Although they also have a ciliary band; and often are roughly the size of single cells – this looks to me a ciliate (so not enteroplea).

    I find the “little contractions” very beautiful and also a big hint. It’s possible this is the motile stage of vorticella – called “telotroch” – during cell division anbound vorticella can produce a free swimming version that goes and settles at a new home. The way it contracts – really reminds me of a telotroch. Also, rotifers often have a foot – and I see no sign of a foot. And finally telotroch have one band at the bottom which propels and feeds them – which this fits the bill.

    I am curious what @laks thinks;)

    Keep exploring!! I will be updating a few features on the site which will allow us to put a template in place for careful microscopic species observations. More on that soon.

    Cheers
    Manu

    @Raju @Manu. It is definitely a ciliate related to vorticella and I agree with @Manu that it might be the Teltroch, although an alternative is that this is a version of the genus that has no stalk? Never seen this size of Vorticella though. Must be about 150-200 microns? Wonder what the stalked form will be like under the foldscope?
