What is an Echidna?
The Echidna (Tachyglossus aculeatus) is a spiky, egg-laying mammal found in Australia and New Guinea. It might look like a porcupine, but it’s actually a unique creature with some fascinating features.

Watch an Echidna
They Lay Eggs – Unlike most mammals, Echidnas lay eggs. The female carries her egg in a pouch until it hatches into a tiny, hairless baby called a puggle.
They Have a Long Tongue – Echidnas have long, sticky tongues that can be as long as their body. They use this tongue to catch ants and termites, which are their favourite food.
They Can Dig Really Well – Echidnas are great diggers. They use their strong claws to dig burrows, hide from predators, and find food.
They Have a Strange Nose – Their nose is long and pointy, and it’s covered with sensitive skin that helps them sniff out food underground.
They Can Roll Into a Ball – If an Echidna feels threatened, it can curl up into a tight ball, hiding its soft belly and protecting itself with its sharp spines.
What They Eat
Echidnas are insectivores, which means they eat insects—especially ants and termites.
They can eat up to 50,000 ants in a single day.
How They Hunt
- They use their sharp claws to dig into ant mounds or termite nests.
- Their long tongue goes straight into the hole, grabbing up ants and termites, which they swallow whole.
- They don’t have teeth, so they grind their food with their hard, ridged palate (the roof of their mouth).
Echidnas have a unique way of getting around.
- Waddling Walk – They move with a slow, waddling gait because of their short legs and wide stance.
- Strong Claws for Climbing – Echidnas are great climbers. They can climb trees and logs using their powerful claws.
- Digging Experts – They use their strong front claws to dig into soil and termite mounds. They can even dig straight down to hide.
- Surprisingly Good Swimmers – Echidnas can swim by paddling with their legs and using their long snout as a snorkel.
How They Keep Safe
Echidnas may look small and slow, but they have amazing ways to protect themselves from predators like dingoes, foxes, and large birds.
- Spiky Armor – Their sharp spines make them hard to bite or swallow. Predators often give up trying.
- Curling into a Ball – When threatened, they tuck their head and legs under their body, turning into a spiky ball that’s tough to attack.
- Burrowing for Safety – Echidnas quickly dig themselves into the ground, leaving only their spiky back exposed.
- Hiding in Logs or Bushes – They use their excellent digging skills to create hiding spots in hollow logs, bushes, or rocky crevices.
With their mix of spiky defence, digging skills, and ability to stay hidden, Echidnas are masters of survival in the wild.
Body Language – When an Echidna feels threatened, it curls up into a ball, hiding its soft belly and showing its sharp spines to protect itself. This is a way of saying, “Stay away!”
Scent Marking – Like many animals, Echidnas leave behind scent trails to mark their territory or communicate their presence. This is especially important during the breeding season when males are looking for females.
Sounds – While not very chatty, Echidnas can make some soft noises. You might hear them huff or grunt, especially when they’re feeling stressed or are in a defensive position.
Breeding Behavior – During mating season, males may follow females, and sometimes you can even hear them grunt or make noises to show interest. The males may circle around a female, which is a sign of courtship.
While Echidnas don’t talk or use loud sounds, their body movements, scent trails, and certain noises help them communicate with each other and their surroundings.
- They help control insect populations by eating lots of ants and termites.
- They are one of the few egg-laying mammals, making them a unique part of the animal kingdom.
- They play an important role in the ecosystems of Australia and New Guinea by digging and mixing up the soil.
Echidnas live all over Australia and New Guinea, from forests to deserts. They can be found in places like:
- The Australian Outback
- Rainforests in Tasmania
- The snowy mountains of Australia
Echidnas love to live in burrows and hide in dense vegetation. You might spot one if you’re lucky—just look for a ball of spiky fur.
