Squirming Peranema, Dancing Nematode

I observed that many foldscopers had made wet mounts of hydrated moss, often in the quest for tardigrades, and I when I found some growing in my backyard, it seemed like the perfect opportunity!

I found a very peculiar creature out of the blue while looking at the sample of hydrated moss (which I collected from my backyard). It had a squirming movement (which made me think at first it was an amoeba because I had never seen an amoeba before), but it also had a flagellum. I got confused and tried to surf the web to find what it was. Then I came across a video on an instagram page, jam_and_germs (

So, from wikipedia: Peranema is a genus of free-living phagotrophic euglenids (Euglenida; Euglenozoa; Excavata). There are more than 20 nominal species, varying in size between 8 and 200 micrometers.[1]Peranema cells are gliding flagellates found in freshwater lakes, ponds and ditches, and are often abundant at the bottom of stagnant pools rich in decaying organic material.[2] Although they belong to the class Euglenoidea, and are morphologically similar to the green EuglenaPeranema have no chloroplasts, and do not conduct autotrophy. Instead, they capture live prey, such as yeast, bacteria and other flagellates, consuming them with the help of a rigid feeding apparatus called a “rod-organ.” 

Next I observed, a nematode and was delighted to see its movements. It’s movement was kind of smooth but at the same time it seemed quite peculiar as if something was trying to hold the nematode back (because of the odd bends that it was taking). Would be grateful if anyone can help me understand why it was moving in this way…

These observation just increase my passion for exploring the microscopic world around me. I would love to get some feedback as well as tips and techniques!
