Dear Folks, Could you please help me to identify this eutardigrada from external morphology? Few month ago I have uploaded the same here with videographs (Foldscopic). But the species need to be identified for cataloging. My wild guess is Hypsibius sp. As the two claws of each leg are straight with only the tip curled…

Desmids & Cyanophycean Species

These are some desmids and cyanophycean algae recorded using foldscope as research tool. This is a part of our unpublished works on Cyanophyceae and Desmids.

Foldscope at Rural Science Fair

Today we have attended and delivered a talk on Foldscope and demonstrated the same with 300 students from different fringe areas of Kokrajhar District, Assam. The program entitled “Gramya Bigyan Mela” (Rural Science fair) was jointly organised by Assam Science Society and Local Education Authority. We are already implementing a project titled – ZOOMING THE…

What is the organism with Frontiana sp

When I was searching for a good videograph of frontiana species, this creatures draws my attention. Can anyone please help me to identify the species

A Giant for ID

It looks like paramoecium sp. Please help to identify the species


I am interested to know the worm like creatures as seen in these videos. The ciliated creatures looks like Prorodon sp. (need experts comments).

Giant for ID

It making me confused after the post of BESTHA SRIKANTH. I was in the direction to give it the identitity as Paramoecium. But after his post, it makes me confused whether it is Frontiana or Paramoecium or any other else. Help needed from the experts to identify the species.

Euglena Sp. In time-lapse

Daphnia Sp.

Conjugation in Spirogyra

It is very interesting to find this reproductive phase in Spirogyra. The sexual reproduction takes place by conjugation in Spirogyra. Zygospore is the final product of conjugation. In this video you can see the lateral conjugation. Between two conjugating cells, conjugation tube is formed. After conjugation tube formation, the protoplasmic mass of the male cell…

Interesting event – I

Another interesting event been recorded from a freshwater samples. Help needed to name it.

What is it?

This egg like creatures draws my attention, when I have seen the movement inside the shell. Please help me to identify the organism.

A mysterious movement

Very recently I have seen this mysterious twisting movement in this unidentified organism. For a while the organisms repeatedly twist and shrinks and then settles.  The circular movement continues for a long time, even when sped up through time-lapse photography. Please help me to identify the species.

Agaricus campestris

When I was collecting water sample from a nearby lake with my students, I have seen this fungus in the surface of the lake. This is a common species of Basidiomycetes fungi – “Agaricus compestris”, commonly called as meadow mushroom. It was found growing alone in the fields having grassy areas. When seen under the…

Dancing Vorticella

The rhythmic movement in Vorticella is really amazing under the foldscope. It is a very interesting, stalked ciliate with bell shaped body and when stimulated, the stalk shortens and causes coiling like a spring.


I know the possibilities is less. But every post on this species increase my attraction to find them out. Very recently posts of  @Yashas makes it doubled. Though several times I work in the foot hill area of Bhutan, but still I have not seen it under the foldscope. In few of my aborted attempt…


Another protist with large amorphous structure. This doesn’t have distinct head or tail. By the help of their pseudopodia they are moving around. In this video, this was found oozing out some algal species when it starts to change direction. Is there any relevant literature on Astramoeba radiosa ? Please help with the link.

Microstomum lineare ?

This is another giant flatworm from the same habitat. It was really incredible to see the feeding behavior of this worm under the foldscope. I consider it as Microstomum lineare after consulting the available information on the species. I request @ Manu sir, to validate the identification. Cheers,


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…

Phacus Sp.

Micro-algae always render my fascination whenever I got chance to observe them under foldscope. This time after viewing the collected sample, this Phacus species have concerned my observation. This unicellular alga has beautiful ornamentation. It exhibits certain features by its flat, leaf like structure. This Euglenozoa species also indicate the organic pollution level of the…

Urocentrum turbo

During the freshwater sample surveys with the students in a local pond I found this special creature. During winter months most of the waterbodies in nearby areas become full of rotting hydrophytes and have different species of ciliates. When I was observing some species of Ciliates and Desmids in the sample, I found this species….


Another Giant ciliate! Euplotes sp.(?). This is purely a freshwater inhabitant. This genus has rows of fused cilia (cirri) along the bottom surface. By the help of these fused cilia, it swims or can walk along the substarte. The cilia move in synchronized waves, propelling the species through the water. They possess a wide cytostome…

Trumpet Animalcules

I was fortunate enough to capture this giant ciliate from a freshwater lake at Assam. This heterotrophic ciliates is also called trumpet animalcules. The name is given due to the horn-shaped/trumpet structure. They are also among the biggest known unicellular organisms. It has a ring of prominent cilia around the anterior by which they sweep…

Mobility in Difflugia sp.

This is my first post of 2019. When I was working on some sample collected from a nearby ditch, found this awesome creature. I find the movement interesting, so sharing with you. It is undoubtedly Difflugia sp. This organism demonstrates the movement of a large testate amoeba using finger-like pseudopods. The taxonomy of this genus…

Unidentified Micro-Structure

I have found this interesting microstructure in a sample collected from a road side ditch. Looks like shell of some organisms. Please help me to name this interesting creature.


Dear Foldscoper, Wish you a Merry Christmas and may this festival bring abundant joy and happiness in your life. May the joy and peace of Christmas be with you all through the Year. May your world be filled with warmth and good cheer obviously with best foldscoping. Regards, Please help in identification of this creature


When I was working to classify the groups of microalgae using foldscope with the sample collected from a nearby ditch, this interesting event have drawn my attention. So, I just can’t stop sharing with you all. Though this event is known to all having life science as one of their subjects in PGs and UGs….
