Animals with Multiple Stomach

There are a million of animals in the world. Each of the animals have different digestive system. In this article we will discuss five animal’s digestive system those have multiple stomach.

05. Ostrich

The ostrich is the largest bird in the world that cannot fly. Although they cannot fly, they can run very fast. They can run at 45 mph (72.42 km/h). Ostriches live in dry habitats where constant food crisis. So they eat whatever is acceptable as food. Ostriches are omnivorous birds.
The list of ostrich food includes grass, grass seeds, plants, wild leaves, shrubs, plant roots, and plant seeds. If there is a food crisis, they also eat insects and lizards.

Ostriches eat mostly green foods that contain large amounts of cellulose. Again, ostriches do not have teeth; they swallow food directly without chewing. So the ostrich’s stomach has been specially adapted to digest food. The ostrich’s stomach has three chambers.
As a result of swallowing food, it goes to the gizzard. In the gizzard the food is crushed, softened and sent to the Proventriculus portion for digestion. Proventriculus contains enzymes needed to digest food. Which digests food and sends it to the intestines. Ostrich food takes about 36 hours to digest. When in danger, ostriches keep long necks with sandy soil in such a way that from a distance they look like they have buried their heads in the sand.

04. Kangaroo

The kangaroos are one of the largest grazing animals on the Australian continent. Kangaroos are herbivores. Grasses, Shrubs, Leaves, Moss, Fruit and Flowering plants are their main food.

Kangaroos have two stomach chambers. Named Saccifrom and Tubiform.  The sassiform chamber contains bacteria, fungi, and protozoa. These help in the fermentation process for digestion. After taking the food, the food first comes into the Sassiform Chamber. The fermentation process of this food is started by the bacteria, fungi, and protozoa present here.

When the fermentation process begins, some indigestible food comes back into the mouth. Which the kangaroo re-chews and sends to the sassiform.

After the fermentation process is completed, it is moved into the second chamber tubeform of the stomach. Tubiform contains all the digestive enzymes and acids that digest food.

Kangaroos drink very little water. They can survive for months without water. As they are mainly herbivores, they absorb essential water from green grass. Kangaroo digested food very slowly. After the digestion process completed, they absorb all the water from the food before the waste removed.

03. Alligator

Alligators have Two stomachs

The alligators are native to only the United States, Mexico, and China. Alligators are fresh-water animals and can be found in lakes, ponds, rivers, and irrigation canals. Alligators are carnivorous. They eat large to small fish, insects, snails, crustaceans, worms, turtles, small mammals, birds etc.
The stomachs of alligators have two parts. One part is small, and another part is big. Alligators swallow large pieces of food or small animals directly during a meal. These large pieces of food first come to the small part of the stomach. This part of the stomach contains the Gastrolith. Gastrolith is stomach stone. Gastrolith crushes large pieces of food. These crushed foods then moved to the second part of the stomach. It contains enzymes and gastric juice, which helps to digest food. After digesting, the food move into the intestine and provides essential nutrients to the body.

The alligators are cool-blooded animals. So they do not have to eat frequently. In the wild, an alligator eats once a week. When they eat extra food, fat starts accumulating at the base of their tail. If the stock of this fat is high, they can survive two years without any food.

02. Camels

Camels have Three Stomachs

The camel is known the ship of the desert. Their bodies are specially adapted to survive in the harsh desert. From  Primitive time, camels have been used as domesticated animals for transportation in the desert.

Camels are herbivores. Like other cattle, they eat all day and eat very fast. The amount of food in the desert is less. So the camel eats whatever it gets in front of its eyes, except the poisonous tree. They even eat thorny trees.

The camel’s stomach has three chambers. Which is about one meter long. The three chambers of the camel’s stomach are named C1, C2 and C3.

C1 is the largest, accounting for 80% of the entire stomach. Food deposited directly in the C1 part. It does not contain any enzymes, but contains microorganisms to digest cellulose. Microorganisms and metabolize cellulose synthesized foods.

Then the food moves in the C2 chamber. In this chamber, the food prepared for digestion. Then the food moves to the C3 chamber. In the C3 chamber, the food fully digested by the juice secreted from the gastric gland and enters the intestine.

01. Reindeer

Reindeer Have Four Stomach

The Reindeer are ruminants mammals. They have a four-chambered stomach. Lichens are their main food. They also eat leaves, birches, sedges, mushrooms, and grasses. These types of foods are cellulose. To digest cellulose, they have a specialized digestive system and microorganisms.

 In the pasture, reindeer eat very fast. While eating, without chewing, they swallow food and fill the stomach.

The first chamber of the Stomach is rumen. Rumen is for Storage. In the pasture, reindeer eat very fast. While eating, without chewing, they swallow food and fill the rumen. After filling the rumen, they stop taking food and bring the food back up into their mouth from the rumen and chew it again. This process called ruminating.

After chewing, the food moves into the Second chamber named Reticulum. Where the microorganism live. Microorganisms help to break cellulose down into simpler substances. This process is fermentation. In the fermentation process, huge methane gas produced, which the deer discharges and brings the food back up into the mouth again. The reindeer chews it up a third time. This time microorganisms mixed with the food and the reindeer chewed them all up too.

After chewing a third time, the food goes to the third chamber named Omasum. Water absorbed in Omasum chamber. After absorbed water, the food moves into the Fourth Chamber named Abomasum. In the Abomasum gastric juices continue digestion. Gastric juices are liquids that help digest food.
