Platypus Quiz: Australia's Egg-Laying, Glowing Mammal

This platypus quiz explores one of the strangest animals on Earth, from its home in eastern Australia and Tasmania and its egg-laying monotreme cousins like the echidna to venomous spurs, electric sensing, fur that glows under UV light, George Shaw's 1799 hoax suspicion and its place on Australia's 20-cent coin and the Sydney Olympics.

Explanations: answer key for all 10 questions

Q1: In which country is the platypus found in the wild?
Answer: Australia
Platypuses live in rivers and lakes in eastern Australia, including Tasmania. They are shy and mostly active at dawn, dusk and night.
Q2: What makes the platypus unusual among mammals?
Answer: It lays eggs
Female platypuses lay one to three small, leathery eggs in a burrow and curl around them to keep them warm for about ten days.
Q3: What is the group of egg-laying mammals called?
Answer: Monotremes
Monotremes are the oldest surviving branch of mammals. Marsupials, such as kangaroos, carry their young in pouches instead.
Q4: Apart from the platypus, which other animals are living monotremes?
Answer: Echidnas
Echidnas, also called spiny anteaters, are the only other living monotremes. They live in Australia and New Guinea.
Q5: What do male platypuses have on their hind legs?
Answer: Venomous spurs
Males have sharp spurs connected to venom glands. The venom is not deadly to people but causes intense, long-lasting pain.
Q6: How does a platypus find food underwater with its eyes, ears and nose closed?
Answer: Electroreception
Its bill has tens of thousands of sensors that detect tiny electric signals from the muscles of shrimp, worms and insect larvae.
Q7: What happens to platypus fur under ultraviolet light?
Answer: It glows blue-green
Scientists reported in 2020 that platypus fur glows blue-green under UV light, a trait called biofluorescence. Its purpose is still unknown.
Q8: When British scientists first examined a platypus specimen in 1799, what did some suspect?
Answer: It was a hoax
Zoologist George Shaw even checked for stitches, thinking someone had sewn a duck's bill onto a mammal. The animal was real.
Q9: How do platypus mothers feed milk to their young?
Answer: Through patches of skin
Platypuses have no nipples. Milk seeps through pores in the mother's skin, and the babies lap it up.
Q10: Which Australian coin features a platypus?
Answer: 20-cent coin
The platypus has appeared on the 20-cent coin since 1966. It was also a mascot of the 2000 Sydney Olympics, named Syd.

Platypus Quiz – Nature's Most Puzzling Mammal

The platypus looks as if it was assembled from spare parts: a duck-like bill, a beaver-like tail, webbed feet and thick fur. When the first specimen reached Britain in 1799, some scientists thought it was a fake. Today we know it is a real and remarkable animal, and one of the oldest kinds of mammal still alive.

Platypuses are monotremes, mammals that lay eggs. Only they and the echidnas belong to this ancient group. Like other mammals, they have fur and feed their young on milk, but the milk seeps through the mother's skin, since platypuses have no nipples.

They are also expert hunters. Diving in rivers and lakes, a platypus closes its eyes, ears and nose and uses its sensitive bill to detect the tiny electric signals made by its prey. It stores food in cheek pouches and eats at the surface. Males defend themselves with venomous spurs, one of the very few venomous mammals.

Scientists keep making new discoveries. In 2020, researchers found that platypus fur glows under ultraviolet light, and studies of its genome have shown a mix of mammal, bird and reptile features. The platypus is listed as near threatened, as droughts, dams and land clearing affect its rivers.

This quiz covers the platypus's biology, history and surprises.

Seeing a platypus in the wild takes patience. Visitors often wait quietly by creeks in places such as Tasmania or Eungella National Park in Queensland at dawn or dusk, watching for ripples and a small brown head. Several Australian zoos and sanctuaries also care for platypuses and breed them in special facilities.
