Protozoa eating each other!
Protozoa under the microscope at 40X 100X and 400X If you look carefully, you can easily see that they produce a "whirlpool" in front! as they swim, and this whirlpool sucks in their prey. You can also see hairs on the front, back and sides of the creatures. They are "hairy monsters" not the smooth things you see in books!
