Amoebozoa and postfloa (Opisthokonta) are two evolutionary branches of protozoa that have evolved different motility and feeding patterns.
Amoeba changes the shape of the body through the telescopic movement of single-celled pseudopods and crawls forward with the help of these pseudopods, capturing small organisms. Amoeba devours these victims in the form of food bubbles, digesting them while they are still alive. Some of the amoeba are larger and can be seen with the naked eye alone. A small number of amoeba are intestinal parasites that cause amoebic dysentery. The amoeba of this group of slime molds is extremely resistant to hunger. When food is depleted, the amoeba is attracted to the chemical distress signals released by their kind and gathers together to form a tiny, flowing "slug." After that, many rod-like branches sprout from it, releasing spores. Each spore in turn develops into a progeny amoeba ready to prey elsewhere at any time.

Many of the protists of this evolutionary branch of the post-flagellate gradually evolved a whip-like flagella for movement in open water. In the early stages of biological evolutionary history, some post-flagellate organisms may have evolved into animals. To this day, the sperm tail of animals still has this flagella. Others are called nucleosomes, and during evolution, their flagella disappeared and effectively transformed into an amoeba-like state. Since fungi also do not have flagella, reproduction also does not require the participation of sperm cells that can move freely. Therefore, nucleoplasma may be closely related to fungi.
Dysentery intra-amoeba - 15-50 μm
This parasitic amoeba parasitizes the human intestine and causes amoebic dysentery. It can contain up to 8 nuclei.
Deeply depressed shell worm - 49-53 μm
This amoeba has a ring-shaped shell covered with small holes. One side is circular in shape and sometimes has ridges that form spines.
Bulbophyllum curvature - 90 μm
This amoeba has a yellow or brown, dome-like ring shell. There is a hole in the flat edge and a series of neat depressions on top of the dome-like shell.
Scotland proto-amoeba - 19-40 μm
Originally, the Scottish protomoesis was found in a estuary in Scotland to be closely related to the amoeba in the liver of carp found in the Czech Republic.
Discoid shell worm - 90-110 μm
This amoeba has two nuclei with a hole at one end of the brownish-yellow shell and protrudes from this hole pseudopod.
Common shell worms - 100-130 μm
This amoeba is mainly found in still water and mud, with a raised shell, holes, and pseudopods protruding from this hole.
Needlethorn crustacea - 120-150 μm
This amoeba parasitizes seaweed in lakes and swamps. Its shell is made up of mud and the cell walls of certain algae, with 4 to 6 spine-like protrusions on it.
Reticulophyllum - 2 cm
This "chocolate tube" or "pipe cleaner" slime mold is originally a clump of cells with many nuclei, on which many spores can germinate.
Oblong sand shell worm - 180-230 μm
The shell of this pond amoeba is made up of tiny sand and cell walls of certain algae species.
Squamous nucleus ovoid trichomes – 1.2-2.2 μm
Previously classified as an evolutionary branch of the order Sun Worm, this posterior flagellar is surrounded by hollow scales or bead-like shells.

One theory of evolution holds that eukaryotes can be divided into two categories: single-flagellar organisms (with one flagella), such as posterior flagellar organisms, and double-flagellate organisms (with two flagellar). Single-flagellar organisms evolved into animals and fungi, and double-flagelled organisms evolved into plants. But the DNA evidence for this theory is ambiguous.
