Alveolata organisms are grouped together because they all share the same anatomical features— a circle of tiny vesicles around cells, hence the name.
Vesicle worms include three types of protists that appear different on the surface but are all single-celled: lumbar flagellar, ciliate, and parietal coverworm. Predatory lumbar flagellar, with the help of its two whip-like flagella, which protrude from the opening in the cell shell and are at right angles to each other. Some lumbar flagellars release stingers to catch food, while others release toxins. The explosive reproduction of the lump-tibbed flagellate is to blame for the occurrence of toxic red tides in parts of the world. A small number of lumbar flagellars are luminous worms that emit light when disturbed at night.
Most ciliates feed on hunting bacteria. The coordinated beating of countless tiny hairy cilia makes the ciliate appear to be moving smoothly and gracefully, and these cilia are distributed throughout the cell. Cilia can also send food into grooves that function like a "mouth." Ciliates are almost ubiquitous, and some even live in the stomachs of herbivorous mammals, helping to digest the plant fiber in the stomach.
In contrast, all apical coverworms are parasites. They get their name from the feature of the top composite. This structure helps the capsizing insects enter live animal cells and seize the nutrients from those cells. Malaria parasites are notorious in the apical cover phylum, which parasitizes in animal red blood cells to obtain nutrients and kill red blood cells at the same time.
M Moser trumpetworm - 2-3mm
Hornworms feed on algae and have a trumpet-shaped body, and their morphology is larger among single-celled organisms.
Stalk ciliates – 50-160 μm
The body of the stalk ciliate is inverted bell shaped, with a stalk at one end, and when the body is stimulated, the stalk curls into a spring-shaped shape.
Dilated nephroplastia - 35-90 μm
This common kidney-shaped ciliella plays an important role in soil ecology, but it is very sensitive to pesticides.
Monk hat nephroformes - 40-110 μm
Pond ciliates are often found in decaying plants in freshwater bodies, which have organelles that store nutrients, vacuoles.
Colon sachet ciliates – 50-130 μm
It is the only known ciliate that parasitizes the human body. They can cause intestinal ulcers, or severe intestinal infections.
Toxoplasma gondii – 6 μm
This parasite spreads between cats and other mammals, including humans, and causes toxoplasmosis. The disease can harm the unborn fetus.
Hornethoea - 225 μm
This is one of the most special of the flagellars, and their explosive reproduction can trigger harmful red tides.
Bare-bellied lumpanthus - 38-50 μm
Chain-like girders can form long, swimming structures of up to 32 cells.
Highly toxic Carliss algae – 17-19 μm
The explosive reproduction of this plankton-peach-shaped girdrichosa can lead to red tide outbreaks, poisoning fish in water bodies.
Chlorella cryptosporidium – 4-6 μm
This apical coverworm causes its host to develop cryptosporidium, causing diarrhea, and they often enter the host in the form of spores through water contaminated with feces.
Plasmodium falciparum - 9-14 μm
It is the malaria parasite that causes the deadliest malaria, and this parasitic capworm is to blame for the death of more than a million people worldwide each year.
Plasmodium - 10-100 μm
The explosive reproduction of this lump-tinder in fresh or seawater can trigger red tides and poison shellfish.
Short Karen algae – 20-40 μm
Formerly known as Dinoflagellates Brevis, this planktonic lumbar flagella is the main cause of red tides in the Gulf of Mexico.
Luminous worms - 200-2000 μm
This luminescent plankton has an airbag that allows them to float in the waters close to sea level.
Hakamatosum hemoglobino – 40-74 μm
It is a large pentagonal creature that has triggered several recorded hazardous blooms in history, a girder that can both photosynthesize and prey on other plankton.
Strong pre-hook algae – 11-24 μm
If humans eat fish contaminated with this plankton, they will die from poisoning.

Early taxonomy divided feeding microorganisms into different taxa in the protozoa phylum of the animal kingdom. Modern protists classify certain microorganisms, such as ciliates and lumpan flagellars, although the specific kinship between the two is controversial.
