Did You Know? 15 Incredible Amoeba Facts

Amoeba facts like they are single-celled organisms are interesting

The amoeba is a microscopic, single-celled organism that is highly mobile. It is able to move around through what is known as pseudopodia. It is a type of protist. Protists can be of different types including amoebas, diatoms, oomycetes, giardia, plasmodium, protozoan, and other related organisms.

It is found in a variety of habitats around the globe. Being a microorganism humans can only see amoeba under a microscope.

These are generally found around the globe in all kinds of environments but especially in freshwater. These can be said to be less evolved simple free-living forms of organisms. Among the amoeba, the amoeba proteus and Chaos carolinense are the best-known forms.

Amoeba Interesting Facts

What type of animal is an amoeba?

The amoebas are very small microscopic unicellular organisms that are mostly cytoplasm held by a cell membrane and comprise a nucleus and a vacuole.

What class of animal does an amoeba belong to?

Amoeba is a type of microorganism that belongs to the class Tubulinea.

How many amoebae are there in the world?

Being microorganisms and single-celled creatures there cannot be any real count of amoeba. We can say that amoebas are countless in number due to their microscopic size and spread in freshwater around the globe.

Where does an amoeba live?

Amoebas generally live in ponds and lakes in the lower reaches. These are found across the globe in freshwater.

What is an amoeba habitat?

Amoebas are found in the bottom of ditches, ponds, lakes, freshwater dams as well as pools of excess water that are stagnant. They can also be found in streams and springs. It is generally averse to sunlight and hence prefers to congregate around the less sunny areas of the freshwater bodies that it is found in.

Who do amoebae live with?

There is a type of social amoeba that lives together with other amoebae. These amoebae seem to realize that it is not easy to survive in this type of environmental condition. Hence they band together and help each other as well. When food is scarce amoeba aggregate to form a larger microorganism. This larger organism's body then moves to an area where food is available. This is a symbiotic form of relationship between amoeba. In freshwater, they are surrounded by several other marine animals such as freshwater butterflyfish, freshwater mussels, freshwater drums, and drum fish.

How long does an amoeba live?

The amoeba is said to divide into two bodies, as clones, every two days. Hence we can conclude that the average life span of an amoeba is only two days.

How do they reproduce?

Amoebas are able to reproduce by cloning themselves by splitting into two, every two days. This is a form of asexual reproduction. The cellular material, as well as the DNA, gets doubled every two days and the amoeba reproduces by forming a clone of itself. Each clone gets the same DNA material required for it to live and similarly reproduce two days hence. The DNA material doubles and attached itself to the membrane of the amoeba. The membrane then separates by creating a wall among itself encircling half parts of the double DNA hence replicating itself.

What is their conservation status?

The amoebas are abundantly found in nature and are not threatened in any way. There is hence no need for any conservation efforts to protect amoeba from extinction.

Amoeba Fun Facts

What do amoebae look like?

Amoebas are formless blobs with jelly-like cytoplasm contained inside them.

Some amoebae (those without shells) look like a blob or shapeless form of jelly when looked at under a microscope. It consists of the cytoplasm, which is jelly-like, and has the nucleus wherein the DNA material is lodged. The internal portion of the amoeba which contains the cytoplasm is known as the vacuole.

How cute are they?

One cannot really categorize the amoeba as being cute in the traditional sense of the word. These are absolutely micro-organic in nature and while they may look interesting under a microscope you would not be able to really categorize them as being cute.

How do they communicate?

The amoebas are able to communicate through the chemical signals that they are able to emanate. The movement of amoeba is through pseudopodia. These do emit certain chemical signals that help the amoeba to be aware of other amoebae around themselves.

How big is an amoeba?

The amoeba is a single-celled microscopic organism. Its dimensions cannot thus be measured in normal measures.

How fast can an amoeba move?

Amoebae can move in their habitat but rather slowly. Its locomotion is primarily through the extension of pseudopodia or false feet. There is also the presence of chemical impulses that prod the amoeba to move ahead albeit slowly. One cannot say that the amoeba swims fast. It is in fact quite slow in its locomotory abilities.

How much does an amoeba weigh?

It would be very difficult to weigh amoebas. However, scientists have calculated that they weigh approximately 6.34931315e-6oz (0.00018g).

What are the male and female names of the species?

The males and females of the tiny amoebas species don't have separate names.

What would you call a baby amoeba?

There is no specific name for a baby amoeba.

What do they eat?

The tiny amoebas eat protozoans, bacteria as well as algal matter. The process of amoeba eating its food is quite distinct. This happens whenever the amoeba is able to detect any living organism that is small enough for it to eat. It protrudes its pseudopodia in such a  manner that it engulfs the bacteria or the algae that it would like to eat. Then it surrounds the food particles from all sides and engulfs them inside its own cell membrane. The chemicals inside the amoeba then ingest the food particles and this is how the amoeba eats.

Are they dangerous?

There is one type of amoeba which is known to be poisonous and can even cause death to humans. This is known as the brain-eating amoeba. The scientific name of this amoeba is Naegleria fowleri. The infection of this type of amoeba is said to have originated in Australia but happens to a larger extent in the US. This form of amoeba is very fond of warm excess water and is found in freshwater lakes, ponds, and other such warm water bodies. Entamoeba histolytica, an anaerobic parasitic amoebozoan from the Entamoeba genus, predominantly infects a human and causes a disease named amoebiasis. Protozoan can cause a disease named Protozal disease. However, filtering protozoan is easier than filtering many viruses and bacteria.

The way this amoeba gets into its victim is through the nose of the humans. Hence infection happens while humans are swimming, doing deep water diving as well as snorkeling. Once it enters through the nose, the brain-eating amoeba makes its way to the brain and starts feeding on it and replicating very fast. This leads to the death of the human infected by this kind of amoeba. However, this is quite rare.

Would they make a good pet?

Amoebas are microscopic and cannot make a good pet.  

Kidadl Advisory: All pets should only be bought from a reputable source. It is recommended that as a potential pet owner you carry out your own research prior to deciding on your pet of choice. Being a pet owner is very rewarding but it also involves commitment, time and money. Ensure that your pet choice complies with the legislation in your state and/or country. You must never take animals from the wild or disturb their habitat. Please check that the pet you are considering buying is not an endangered species, or listed on the CITES list, and has not been taken from the wild for the pet trade.

Did you know...

Amoebas can be very useful in releasing nutrients into the soil. First, the bacteria ingest nutritive matter from their habitat. When the amoeba eats up the bacteria, these nutrients are released back into the soil.

How many cells does an amoeba have?

An amoeba has only one cell.

How does an amoeba move?

An amoeba, comprising of a nucleus and a vacuole, moves by using its bulging parts known as pseudopodia, meaning false feet. These are the extension of the amoeba’s cell membrane. They can reach out and grab a surface using a pseudopod and even crawl forward with it.
