Where does the platypus get its name?

In English, it is called "platypus", but in fact, in the case of the Japanese name, it is named "kamonohashi". This time, why did it come to be called kamonohasi by its Japanese name? We will introduce its origin.

In fact, it is believed that its beak resembled a duck, so it came to be called a platypus.

And the origin of the English name is Greek, and it is said that it comes from "flat feet or flat feet". It is true that the feet of the platypus have flat feet with webs. You can see that both names are named after the characteristics of the body.

Why do platypus live there?

The platypus has a habit of living near the water. This may be related to the fact that their food is creatures living in the water.

The platypus has webbed feet and is built for swimming. They can also walk on land, but their movements are clumsy compared to swimming.

If the nest is far from the water, there is a risk of being attacked by other animals during migration. That’s why platypuses live near the water and make nests.

What does a platypus eat?

The platypus eats insects, larvae, worms, and clams that live on the bottom of the water. They catch prey hiding in the soil with their beaks and then crush and eat them after coming to the surface of the water.

However, the platypus does not have teeth to bite and crush prey. How do they crush prey without teeth?

The platypus also takes gravel into its mouth when it catches prey.

They use this gravel to their advantage. By chewing prey and gravel together in their mouth, the gravel crushes the prey instead of teeth. This is a method they developed because they don’t have teeth.

How can a platypus have no teeth?

The platypus did not lose its teeth from the beginning. It is known that their ancestor, “obdurodon,” had teeth.

Teeth are more likely to remain in the process of evolution, but the platypus is thought to be the only animal that has lost its teeth. Why did the platypus lose its teeth?

The structure of the “beak” is largely responsible for this. The platypus’s beak has more developed sensory organs than obdurodon. The reason for the development of sensory organs is that their diet has changed.

Obdurodon caught and ate fish swimming in the water, but the platypus has to search for insects and clams that live on the bottom of the water. The platypus dives into the water to find food, but it closes its eyes while diving. How does it find food without using its eyes?

The sensory organs in the beak are useful for this. Specifically, they sense the electricity emitted by living things and use their beaks to catch prey. The reason why the sensory organs are supported is that there are many nerves passing through the beak. Due to the increase in nerves, there is no space for teeth to grow and they have lost their teeth.

Securing food is necessary for any living creature to survive. The platypus lost its teeth by prioritizing its ability to sense food, but instead of teeth, gravel crushes food. It’s important to live by devising ways to make up for what you’ve lost.

Platypus lays eggs, but are they mammals?

The platypus is an animal that only lives in Australia, so it is a strange creature that people from other countries have never seen before. In around 1798, the first platypus specimen was sent to England. The scholar who saw the platypus suspected that it was a fake made by a taxidermist who had put together several animals.

Certainly, the platypus has an unusual appearance among mammals. The beak is similar to that of a duck, and the breeding method is closer to that of reptiles and birds because they lay eggs. Scholars were puzzled as to how to classify this creature.

The decisive factor in classifying it as a mammal was the presence of “mammary glands.” Although they lay eggs, they were classified as mammals because they nurse their young with milk after hatching.

Is it true that platypus is poisonous? How strong is the poison?

Male platypuses have venomous spurs at the base of their legs. I wonder how strong the poison is and whether it affects humans. Many people may think that they do not have a strong poison because of their appearance. However, the platypus’s venom is so strong that dogs and small animals die when stung.

Would humans die if they were stung? In the case of humans, they do not die, but it is said that they experience pain that cannot be relieved even by morphine, a painkiller. It’s hard to imagine how painful it is when morphine doesn’t work.

The platypus’s venom tends to increase during the breeding season. This period is around October to November. Be careful when you go to the waterside in Australia.
