The Platypus doesn’t actually have a stomach, meaning they don’t have a specialized organ to secrete digestive juices to break down food and extract nutrients from it. Instead, the Platypus uses an incredibly efficient process in which the bill acts as a sort of mechanical filter.
Platypuses will often plunge their bill into muddy bottoms, searching for food with their huge, sensitive pores. As the platypus searches for food with its bill, the hairs lining the bill detect movement of prey, such as aquatic larvae and small invertebrates.
Once detected, the platypus will suck up the prey with its bill, trapping the prey between its tongue and roof of its mouth. The Platypus also has an extremely efficient digestive system in which after sucking up their prey, they are able to separate the food particles from the water before swallowing.
The food will then move into the intestine, where it is digested and the nutrients are kept. The remaining waste, including what couldn’t be digested, is eliminated through the cloaca. This process allows the platypus to take advantage of nutrient-rich food sources without requiring a stomach.

Did platypus ever have stomach?
Yes, platypus have had a stomach since they first evolved around 168 million years ago. The platypus’ stomach is a simple, single-chambered organ, which is located near the bottom of the abdomen. It is made of the same epithelial tissue as the intestines and is used to break down food, extracting nutrients and passing the rest to the intestines.
The platypus’ stomach produces hydrochloric acid to break down food, and can secrete enzymes to help break down plant matter. The inner lining of the stomach is modified to be waterproof, which helps protect its tissue from acid.
While platypus lack in variety of digestive organs found in other mammals, their stomachs are quite effective for their diet of insects and other aquatic organisms.
What animal has no stomach?
An animal that has no stomach is the humboldt squid. These marine creatures are carnivorous cephalopods with no internal stomach. They take in their food, digest it, and then excrete the waste almost immediately.
Humboldt squids are found in the Eastern Pacific Ocean, mainly in the waters around Peru, Chile and the Galápagos Islands. They feed on fish and crustaceans, using their powerful arms and beak-like jaws to tear apart their prey.
These squids are considered top predators in the region and can grow up to 60-90 cm in length.
Does a kangaroo have a stomach?
Yes, a kangaroo does have a stomach. All animals with the ability to digest food have a stomach, and kangaroos are no exception. A kangaroo’s stomach consists of four compartments, which is similar to the stomach of most other mammals.
These compartments include the rumen, reticulum, omasum, and abomasum. The kangaroo’s stomach serves multiple functions, including the breakdown of food, absorption of nutrients and electrolytes, and creation of digestive enzymes.
Food passes through the compartments of the kangaroo’s stomach in a specific order, beginning with the rumen and ending with abomasum, before being passed into the small intestine. A kangaroo’s diet primarily consists of grasses, but they will also eat insects, roots, and young shoots.
In the wild, kangaroos typically graze on grasses in the evenings when temperatures are cooler.
Why did the platypus lose its stomach?
The platypus has evolved without a stomach over time due to changes in its diet and habitat. Research suggests that the platypus is the only known monotreme to have lost its stomach, probably due to its switch from a mainly carnivorous diet to a mainly insect-based one.
Because the platypus is an ambush predator, it has adapted to eat its prey whole. As a result, its diet no longer consists of large chunks of meat which necessitate gastric breakdown; instead, its food is already broken down, allowing the animal to absorb nutrients more efficiently.
Thus, the platypus no longer needs a stomach to aid in digestion, so it has evolved to live without one.
In addition, the platypus’ changing environment has also contributed to the disappearance of its stomach. The platypus inhabits wet areas, meaning that its water supply is plentiful. Thus, it no longer needs a stomach to store food for periods without access to water.
Moreover, it spends less time foraging for food since its diet consists mainly of insects that can be caught quickly and with ease. All these factors have led to the platypus losing its stomach over time.
Which animal has blue blood?
The blue-blooded animal is the horseshoe crab, which can be found along the ocean floor in the Eastern Atlantic, as well as the Eastern Pacific near Japan and Korea. The horseshoe crab’s blue colored blood is not really blue.
It is actually a colourless liquid that contains a component called hemocyanin, which contains copper. Copper is what gives the horseshoe crab’s blood a blue colour. Horseshoe crabs have an immune system that is very efficient in scavenging for dangerous bacteria.
This unique ability is why their blood has become a key component in the medical industry. Their blood is harvested for use as a component of bacteria tests in the production of medicines, vaccines, and medical implants.
In addition, the horseshoe crab can also regenerate its own limbs, making it incredibly tough and resilient.
How many stomachs does a gorilla have?
A gorilla, like all mammals, has only one stomach. The stomach is connected to the small intestine and to the large intestine, which plays a part in digestion. However, gorillas are herbivores, meaning they feed mainly on plants.
As a result, they have a larger cecum (a pouch-like organ where some digestion takes place) than other animals such as carnivores. This allows them to digest the cellulose in plants more effectively.
Which animal has highest digestive system?
The animal with the highest digestive system is the kangaroo. Kangaroos have some of the most sophisticated digestive systems amongst mammals, and have a very large cecum, which enables them to digest cellulose and extract the maximum nutrition out of their plant-based diet.
A kangaroo’s digestive system is made up of four distinct chambers which work together to break down food, extract the key nutrients, and discharge the indigestible matter as waste. The first chamber is the mouth where the food is chewed and mixed with saliva.
The second chamber is the stomach, which contains hydrochloric acid and enzymes to break down food further. Following that, the small intestine absorbs the nutrients, and finally, the large cecum and faecal matter house the microorganisms which help extract the last of the nutrients before the waste matter is expelled.
Kangaroos also take longer to digest food, with the food taking 3-4 days to travel through their entire digestive system.
