20 Lesser-Known Facts About Platypus

1. Platypuses Are Venomous

One of the most surprising facts about Platypus is that they are venomous. Male platypuses have spurs on their hind legs connected to venom glands. While their venom is not lethal to humans, it can cause intense pain and swelling.

The venom is primarily used during the mating season to assert dominance over rival males. Though it is not deadly, the sting is potent enough to incapacitate smaller animals and cause significant discomfort to larger predators.

2. The Plural of Platypus is… Platypus?

The plural form of platypus is often debated. Derived from Greek, the correct plural should technically be “platypodes.” However, in common usage, both “platypuses” and “platypus” are accepted.

Scientists and conservationists sometimes prefer “platypus” when referring to multiple animals, maintaining the simplicity of language. Regardless of the plural form, this fascinating creature continues to capture attention worldwide.

3. Platypuses Lay Eggs

Despite being mammals, platypuses are one of the few species that lay eggs. They belong to a group of egg-laying mammals called monotremes, which includes only five species, all found in Australia and New Guinea.

Female platypuses usually lay 1-3 eggs and incubate them in burrows. This unique reproductive method sets them apart from most other mammals, making them one of nature’s most intriguing animals.

4. Platypuses Are Well-Dressed with Two Layers of Fur

Platypuses are known for their luxurious fur, which serves both as insulation and waterproofing. They have two layers of fur that trap a layer of air against their skin, keeping them buoyant and dry even when they spend up to 12 hours a day underwater hunting for food.

Their fur provides protection against the cold waters of their natural habitat, ensuring they remain comfortable while submerged.

5. They Glow Under UV Light

One of the strangest facts about platypus is their ability to biofluoresce. When placed under UV light, platypuses emit a blue-green glow. The purpose of this glow is still a mystery to scientists, but it has been observed in several other mammals as well.

The fact that they glow under UV light adds to the enigmatic nature of this animal, prompting further research into the evolutionary reasons behind biofluorescence.

6. Platypuses Are Adorable as Babies

Platypus babies are often referred to as “puggles,” and they are undeniably adorable. Puggles spend the first few months of their lives in their mothers’ burrows, nursing and developing until they are ready to venture out into the world.

Though puggles are cute, they grow up quickly, leaving the nest after about four months. Once they mature, they become part of the juvenile platypus population, ready to explore the waterways on their own.

7. Platypuses Are Becoming Harder to Spot

Due to environmental threats such as droughts, bushfires, and climate change, platypuses are becoming increasingly difficult to spot in the wild. Their habitats are being affected, leading to a decline in their population.

Conservation efforts are more critical than ever to protect this species from further decline. Platypuses play an important role in their ecosystem, and preserving their habitat is vital for their survival.

8. One of the Few Egg-Laying Mammals

As monotremes, platypuses are one of the few mammals that lay eggs. In fact, they are one of only five monotreme species left on Earth. Along with four species of echidna, platypuses represent an ancient branch of mammals that diverged millions of years ago.

Their ability to lay eggs while still possessing mammalian traits, such as fur and milk production, makes them a true evolutionary marvel.

9. Platypus Bills Serve as Sensory Organs

A platypus’ most distinctive feature is its bill, which resembles a duck’s. However, unlike a duck, the platypus uses its bill as a powerful sensory organ. When diving underwater, they close their eyes, ears, and nostrils, relying solely on their bill to detect prey.

The bill is equipped with push rods that sense water movements and electroreceptors that detect the electrical signals generated by the muscles of their prey, making them highly effective hunters.

10. Females Don’t Have Nipples

Another fascinating fact about Platypus is that female platypuses do not have nipples. Instead, they secrete milk through their skin. The milk pools on the mother’s belly fur, and the young platypuses lick it off to feed.

This method of lactation is unique to monotremes and further highlights the evolutionary differences between platypuses and other mammals.

11. Platypuses Don’t Have Teeth

Unlike most mammals, platypuses do not have teeth. Instead, they have grinding plates that they use to break down their food. Their diet consists mainly of small invertebrates, such as larvae and worms, which they scoop up along with gravel from the bottom of rivers and lakes. They use the gravel and their grinding plates to mash up their food before swallowing it.

12. Some Platypuses Hibernate in Winter

During the colder months, some platypuses enter a state of torpor, reducing their body temperature and metabolism. This behavior, similar to hibernation, allows them to conserve energy when food is scarce. While platypuses in captivity and in certain regions of Australia have been observed hibernating, not all populations exhibit this behavior. It remains a subject of study among researchers.

13. Platypuses Are Excellent Swimmers

Though awkward on land, platypuses are excellent swimmers. They can swim at speeds of up to one meter per second, thanks to their streamlined bodies and webbed feet.

While swimming, the webbing on their feet extends, acting like flippers. However, when on land, the webbing retracts, revealing claws that help them dig burrows along riverbanks.

14. The Platypus Was Once Believed to Be a Hoax

When the first specimen of a platypus was sent to British scientists in the late 18th century, many believed it was a hoax. The platypus’ unique combination of features—a bill like a duck, webbed feet, fur like an otter, and the ability to lay eggs—was so bizarre that some naturalists thought it was a stitched-together fake. It wasn’t until further studies were conducted that the platypus was accepted as a genuine species.

15. Platypuses Dig Burrows and Create Plugs

Platypuses are skilled burrowers, digging intricate tunnels along riverbanks. They create two types of burrows: nesting burrows, where females lay eggs and raise their young, and camping burrows, where they rest.

A unique behavior observed in platypuses is their ability to create plugs within their burrows. These plugs are believed to confuse predators, making it more difficult for them to locate the platypus inside.

16. Platypuses Evolved from Ancient Mammals

The platypus has a long evolutionary history, dating back over 110 million years. One of its ancient ancestors, Steropodon galmani, lived during the Cretaceous period alongside dinosaurs.

Fossils of Steropodon reveal that it was similar in size to modern platypuses but had teeth, unlike today’s toothless platypus. The platypus’ ancient lineage is evident in its unique skeletal structure and primitive traits.

17. Platypuses Are at Risk of Extinction

Unfortunately, the platypus is listed as Near Threatened on the International Union for Conservation of Nature (IUCN) Red List. Habitat loss, climate change, and extreme droughts are significant threats to their survival. Recent bushfires in Australia have further endangered their population. Conservation efforts are urgently needed to protect this unique mammal from extinction.

18. Platypus Milk May Help Combat Superbugs

In 2010, researchers discovered that platypus milk contains antibacterial properties that could help in the fight against antibiotic-resistant bacteria. The unique protein structure in their milk could provide new insights into combating superbugs, offering a potential solution to one of the most pressing health challenges facing modern medicine.

19. Platypuses Have 10 Sex Chromosomes

Unlike most mammals, which have only two sex chromosomes, platypuses have 10. Five X chromosomes and five Y chromosomes determine the sex of the platypus. Interestingly, some of the genes in these chromosomes are shared with birds, suggesting that platypuses may hold clues to the evolutionary history of sex chromosomes in mammals and birds.

20. Platypuses Don’t Have Stomachs

Another strange fact about Platypus is that they lack stomachs. Instead of passing food through a stomach filled with digestive enzymes, their food goes directly from their esophagus to their intestines. This adaptation is believed to be the result of their diet, which consists of small invertebrates and bottom-dwelling creatures that do not require extensive digestion.
