What should you know about Platypus?
The platypus (Ornithorhynchus anatinus) breaks so many mammalian rules that the first specimen sent to Britain was assumed to be a hoax. Full profile in our platypus guide.
What should you know about it lays eggs?
One of only five surviving monotremes — egg-laying mammals — alongside four echidna species. It lays eggs is one of the details people actually search for about Platypus. It holds as a field note from Eastern Australia and Tasmania; it is not a care sheet and not a substitute for the species guide.
Is it true that males are venomous?
A spur on each hind leg delivers venom powerful enough to cause excruciating, long-lasting pain in humans. Very few mammals are venomous at all. Males are venomous is one of the details people actually search for about Platypus. It holds as a field note from Eastern Australia and Tasmania; it is not a care sheet and not a substitute for the species guide.
What should you know about it hunts with its eyes closed?
Eyes, ears and nostrils shut underwater. The bill detects the electrical fields of muscle contractions in prey — electroreception, almost unknown in mammals. It hunts with its eyes closed is one of the details people actually search for about Platypus. It holds as a field note from Eastern Australia and Tasmania; it is not a care sheet and not a substitute for the species guide.
Is it true that there are no nipples?
Milk is secreted through skin patches and the young lap it from the mother's fur. There are no nipples is one of the details people actually search for about Platypus. It holds as a field note from Eastern Australia and Tasmania; it is not a care sheet and not a substitute for the species guide.
What should you know about ten sex chromosomes?
Against the usual two, and the system resembles a bird's more than a mammal's. Ten sex chromosomes is one of the details people actually search for about Platypus. It holds as a field note from Eastern Australia and Tasmania; it is not a care sheet and not a substitute for the species guide.
What should you know about their fur fluoresces?
Under ultraviolet light platypus fur glows blue-green. The function, if any, is unknown. Their fur fluoresces is one of the details people actually search for about Platypus. It holds as a field note from Eastern Australia and Tasmania; it is not a care sheet and not a substitute for the species guide.
What should you know about no stomach?
The oesophagus connects almost directly to the intestine — the stomach was lost in this lineage. No stomach is one of the details people actually search for about Platypus. It holds as a field note from Eastern Australia and Tasmania; it is not a care sheet and not a substitute for the species guide.
What should you know about they store food in cheek pouches?
Prey is collected underwater then ground at the surface using horny plates, since adults have no teeth. They store food in cheek pouches is one of the details people actually search for about Platypus. It holds as a field note from Eastern Australia and Tasmania; it is not a care sheet and not a substitute for the species guide.
Is it true that the first specimen was thought a fake?
British scientists in 1799 suspected a duck's bill had been sewn onto a beaver-like body. The first specimen was thought a fake is one of the details people actually search for about Platypus. It holds as a field note from Eastern Australia and Tasmania; it is not a care sheet and not a substitute for the species guide.
Is it true that they are a very old lineage?
Monotremes split from other mammals more than 160 million years ago. They are a very old lineage is one of the details people actually search for about Platypus. It holds as a field note from Eastern Australia and Tasmania; it is not a care sheet and not a substitute for the species guide.
Is it true that they are Near Threatened?
River regulation, drought, habitat loss, illegal net drowning and predation by foxes and dogs have driven local declines. They are Near Threatened is one of the details people actually search for about Platypus. It holds as a field note from Eastern Australia and Tasmania; it is not a care sheet and not a substitute for the species guide.
Is it true that drought is the growing threat?
Platypuses need permanent water. Longer and more severe drought under climate change is now among the most serious pressures on them. A fact list is not an IUCN assessment. Platypus still needs habitat, enforcement and honest funding — see the full species guide rather than stopping at trivia.

What is this briefing not?
This briefing is not a substitute for the full Platypus wildlife guide, not a pet-care manual, and not a first-person field dispatch. It is a desk-researched explainer for people who searched a specific question about Platypus. The setting is Eastern Australia and Tasmania.
12 Amazing Facts About Platypuses (Venomous, Egg-Laying, and They Glow) sits in the newsroom as a species explainer. It is not a Field notes dispatch from a partner clinic, and it is not a reason to keep Platypus. Location context: Eastern Australia and Tasmania.
Who should skip this page?
Skip this page if you wanted a complete IUCN-style species profile, veterinary advice, or permission to keep Platypus as a pet. You will not find those here. Read the wildlife guide next if you need status, range and sources in one place.
Skip it if you needed veterinary instructions, a travel itinerary, or a fundraising story dressed up as science. The skip is the point: a page that cannot say no is not a guide.
How does this briefing compare to the full species guide?
This page answers the search in the headline. The wildlife guide answers status, threats, and what is actually known. Use both; do not cite the listicle as if it were the Red List. Electroreception, venomous spurs, milk without nipples, ten sex chromosomes and fur that fluoresces.
| Takeaway |
|---|
| Platypuses are monotremes — egg-laying mammals, one of only five surviving species. |
| Males carry venomous spurs on the hind legs, rare among mammals. |
| They hunt with eyes, ears and nostrils shut, locating prey by electroreception in the bill. |
| There are no nipples: milk is secreted through skin patches and lapped from the fur. |
The canonical profile is the Platypus wildlife guide — IUCN context, range, and the sources behind the numbers. This newsroom page is the short, question-shaped route into that guide.
What is the catch with a short wildlife briefing?
The catch with wildlife listicles is that a true fact can still be the wrong takeaway. “Amazing” is not the same as “safe to keep”, and a number without a source is trivia. Every figure on this page should be read against the cited IUCN or zoo pages, not against a screenshot.
Factory “12 facts” pages elsewhere on the web pad the same three sentences. Here each heading is a real question, each answer is meant to stand alone, and the sources at the end are the audit trail. If a number is not on this page or in those sources, we did not invent it.
What should you do after reading this?
Use this briefing to answer the question in the title, then go to the species guide for status and sources. If you want to help Platypus, fund habitat and enforcement — do not buy the animal. Platypuses are egg-laying mammals that hunt with their eyes shut using electroreception in the bill, have venomous spurs on the hind legs of males, sweat milk rather than having nipples, and carry ten sex chromosomes.
If you want to support WARN’s partner work, donate knowing we are a community interest company, not a registered charity. If you want the animal itself, you have the wrong page.
Read the verdict on the first screen, the skip-if before you share the page, and the sources at the end before you quote a number. That is the whole contract of this briefing.
