Gawd, I remember back in grade school the teacher would have the click-clacking film projector and it always began with protozoa.

Call me stupid, but what is the significance of protozoa?

> ... what is the significance of protozoa?

They are considered the earliest and simplest of God's creatures, as the name itself states. As such they hold a particular and notable place in the vast expanse of living things.

They look neat under a microscope.

Thinking of selling a line of stuffed animals, starting with the tardigrade. The one in your pic would make a nice addition.

protozoa ping.

All protozoa are heterotrophic, deriving nutrients from other organisms, either by ingesting them whole by phagocytosis or taking up dissolved organic matter or micro-particles (osmotrophy). Phagocytosis may involve engulfing organic particles with pseudopodia (as amoebae do), taking in food through a specialized mouth-like aperture called a cytostome, or using stiffened ingestion organelles

In other words, communists, marxists, liberals and democrats are all protozoa.

This reminds me of what great teachers I had, growing up in the 70s in Littleton, Colorado. Biology, English, Geography, American Civ; they were all probably college level compared to the quality these kids get today.

Not sure whether or not is was single celled or not, but around 1966 my biology teacher too us on a field trip beyond the football field, where there was a pond. We collected samples of the water and some muck, some algae. We went back to class and made slides, and looked under the microscopes. Every desk had one. We were amazed at what we saw. I identified a rotifer, and a hydra, and got an “A”. Made my day.

What is the opposite of protozoa? Contozoa or Antitozoa?
