Animalcule Gourmet or Glutton?

Paramecia feed on microorganisms, like bacteria and algae. Rotifers eat tiny particles of organic detritus (bits of vegetation), dead bacteria, algae, and protozoans (one-celled life forms.)
To maintain a specimen farm in my yard, I periodically add dried grass, dead leaves, bits of vegetation to my rainwater plate. The wind adds pollen and other microscopic foods. Algae grows in there, and the natural life/death cycle provides additional nutrients to the inhabitants.
This video captures an interesting food source, some detritus or other which has many animalcules feasting with vigor.

Beautiful images. I see them eating or nibbling. Frankly to me they look a lot like dogs or cats, not simple, primitive organisms.

Frankly, I was mesmerized, and I almost forgot to start the video! I spent a bit of time saying "Oh, WOW!" LOL!
