Sampled moss from a neighborhood stream in Dublin, CA, and found this interesting fellow. No idea what it could be but it looks like it holds to something with its back while it opens its mouth wide and eats (at least that is my interpretation of what is going on). Any idea on what creature this might be?
Check between 12 and 16 seconds into the movie for the part in which I think it might be eating something.
Here are also some photos for those of you who don’t want to watch the video:
Happy foldscoping 🙂
Fortunately this one seems to be a common creature. Thus, I think I found it by simply googling “Microscopic pond animal identification”. It was like the 5th hit or so. I think that what I found here is a Rotifer, which is a multicellular animal. More specific, I think this could be a Bdelloidea. These animals eat particles of up to 10µm in size. If you look close at the video, around second 12-16 and at the end again, you can see how the animal sucks the larger particles in. Have a look at a large particle and you can follow the flow into the mouth.
