The Strangest Animals in the World: 10 Creatures You Won't Believe Are Real

Meet the strangest animals on Earth, on land and in the sea: from the egg-laying platypus to the tardigrade that survives space, with weird facts about each one.

Nature is full of surprises. Some animals look like they’ve stepped out of a science-fiction film, yet they’re completely real and share this planet with us. Here’s a list of the strangest animals in the world, with the science behind what makes them so unusual.

1. The axolotl: the salamander that regrows body parts

The axolotl is a Mexican amphibian that always seems to be smiling, with feathery gills around its head. Strangely, it keeps its larval features for its whole life instead of transforming like other salamanders.

Its most astonishing trick is regrowing lost limbs, and even parts of its heart and brain, which is why scientists study it so closely. Sadly, it is critically endangered in its natural home near Mexico City.

2. The platypus: the mammal that lays eggs

The platypus lives in Australia and looks like several animals combined: a duck-like bill, a beaver-like tail and webbed feet.

Its oddities include:

  • It’s a mammal that lays eggs.
  • Its bill senses the electrical signals given off by prey underwater.
  • Males have a venomous spur on their back legs.
  • It has no true stomach; its gullet connects straight to the intestine.

3. The aye-aye: the finger tapper

The aye-aye is a nocturnal lemur from Madagascar. It has an extremely long, thin middle finger that it uses to tap on tree trunks, listening for the echo to find hidden grubs, which it then hooks out with the same finger.

4. The blobfish: “the world’s ugliest animal”

The blobfish became famous after it was voted “the world’s ugliest animal” in a light-hearted 2013 poll. But the fish has been treated unfairly!

It lives deep in the ocean off Australia and New Zealand, where the pressure is enormous, and down there it looks like an ordinary fish. Its famous saggy look only appears when it’s brought to the surface and the pressure around it suddenly drops.

5. The pangolin: the armoured mammal

The pangolin is the only mammal covered in hard scales made of keratin, the same material as our fingernails. When threatened, it rolls itself into an armoured ball.

Sadly, it is among the most poached and illegally trafficked mammals in the world.

6. The mantis shrimp: the fastest punch

The mantis shrimp looks small and colourful, but it delivers one of the fastest strikes in the animal kingdom, powerful enough to smash snail shells in an instant.

Its eyes are among the most complex in nature, with 12 to 16 types of colour-detecting cells, while humans have just 3.

Did you know? A mantis shrimp punches so fast that it creates tiny bubbles in the water that collapse with a second shockwave, so its prey gets hit twice!

7. The tardigrade: the nearly indestructible animal

The tardigrade (or water bear) is microscopic, only about half a millimetre long. But it’s the undisputed champion of survival: it can enter a dormant state, losing most of its body water, and endure extreme drought, cold and radiation.

Some even survived exposure to the vacuum of space in a 2007 experiment!

8. The naked mole-rat: the long-lived cancer fighter

The naked mole-rat looks odd with its wrinkly pink skin and protruding teeth. Scientists are fascinated by it because it lives for more than 30 years, far longer than rodents of a similar size, and very rarely gets cancer.

It lives in underground colonies with a single breeding “queen”, just like a beehive.

9. The star-nosed mole: the world’s fastest eater

This mole has 22 fleshy tentacles around its nose in a star shape, packed with extremely sensitive touch receptors. Thanks to them, it can identify and swallow food in less than a quarter of a second, making it one of the fastest eaters on Earth.

10. The leafy seadragon: a fish disguised as seaweed

The leafy seadragon lives off southern Australia. Its body is covered in leaf-like flaps that let it vanish among the seaweed. It’s a relative of the seahorse and, like seahorses, the male carries the eggs until they hatch.

Frequently asked questions

What is the strangest animal in the world?

There’s no single answer, but the platypus tops many lists because it combines features of mammals, birds and reptiles.

What is the strangest animal in the sea?

Some of the strangest sea creatures are the blobfish, the mantis shrimp and the leafy seadragon.

Why do some animals look so strange?

Because each odd feature is usually a clever adaptation to the animal’s environment, such as camouflage, hunting in the dark or surviving harsh conditions.

Key takeaway

From the egg-laying platypus to the tardigrade that survives space, these animals prove that nature is stranger than fiction. Behind every bizarre shape is an amazing story of adaptation, and a responsibility for us to protect these creatures from extinction.
