Hey folks, here’s a post about my journey in the Himalayas with Foldscope. Follow me on Twitter and Researchgate to know more.

Lets continue…

As I mentioned in my earlier post that we are done with the journey, in the subsequent posts I will be discussing about the methodologies to find them.

NOW!!! how does one find a tardigrade?? (water bear)

1. Tardigrades are usually found in moss or lichens.

2. Collect a clump of moss or lichen (dry or wet) and place in a shallow dish, such as a Petri dish.

3. Soak in water (preferably Distilled water, bottled spring water, bottled mineral water or fresh rain water) for 3-24 hours. Tap water is harmful because the water will be chlorinated.

4. While soaking make sure the samples are completely soaked, remove and discard it after they’re soaked.

5. Use a micropipette or a small dropper to transfer the water to a cavity slide. Use a Foldscope to observe and find a Tardigrade.

Invert the lichen sample so more of the surface is available for soaking.

Found these guys in separate samples collected from the Himalayas

Right – Heterotardigrada; Left – Eutardigrada

A few Tardigrades under a single frame. These were all transferred from different samples into a single cavity slide with few drops of water from the dish.

PS: Tardigrades in general are very hard to find and deal with as they’re microscopic animals. The hydration is very essential otherwise they will remain in their Tun state
