protozoan

It’s strong enough to show your budding biologist protozoa, cell walls, bacteria, and more.

Horses, sheep, dogs, and other animals are also affected with diseases caused by the same group of Protozoan parasites.

This disease is caused by a Protozoan parasite, a trypanosome, which is transmitted from one host to another by the tsetse-fly.

The shelly agglomerates of these Protozoan Rhizopods constitute now very important rocks.

Naturally in the early protozoan colonies, and in forms like hydra, these functions predominated.

This is the blastula stage occurring universally in all Metazoa, probably representing an ancestral Protozoan colony in phylogeny.
