Predation
- no defensive or offensive weapons
- a threatened echidna pulls its head in and curls into a ball to protect its belly so that all that is presented is a ball of spines
- in soft soil, it can also dig in and disappear rapidly climb into trees or climb fences
How does an echidna protect itself from predators?
The echidna digs straight into the dirt until only a spiny rear end can be seen, making it almost impossible for a predator to grab and pull it out. It can also protect itself by curling up into a tight, spiky ball, hiding its face and feet.
How do echidnas keep cool in hot climates?
Behavioural: In order for echidnas to keep cool in hot climates they find shelter. Furthermore, how do echidnas survive in their environment? To survive extremes in weather echidnas burrow into the soil, hide under vegetation and shelter in hollow logs, rock crevices and in burrows created by wombats or rabbits.
What do Echidnas use their legs for?
The echidna’s short legs are ideal for digging. The hind legs point backward, with an extra-long claw on the second toe that can be used to “comb” or scratch out dirt and bugs that get wedged between the echidna’s spines.
Do echidnas bury themselves?
In soft soils echidnas will sometimes bury themselves if the opportunity arises. density of fur varies with habitat – dense in Tasmania and in alpine regions; in dry and northern areas, fur is sparse covered with tough, hairless skin containing glands and sensory receptors nostrils are at the end of the snout
Can echidnas shoot their quills?
Echidnas Can Control Their Spines An echidna erects its spines for protection (like the picture above), to anchor itself against a log, to help it climb, and to help upright itself after it has fallen or placed on its back. It cannot, however, throw or eject its spines as the legend said.
What helps an echidna survive?
A structural adaptation of the echidna is the spines that cover its back area. These spines are used for protection against predators. Echidnas have a long snout and tongue, which are another structural adaptation that allows the species to reach deep into ant and termite hills to find food.
What do echidnas use their front legs for?
The short, stout limbs of an echidna are well-suited for scratching and digging in the soil. The front feet have five flattened claws which are used to dig forest litter, burrow, and tear open logs and termite mounds. The hind feet point backwards, and help to push soil away when the animal is burrowing.

Why do echidnas have 4 heads?
But in short-beaked echidnas, the cavernosum was merged while the spongiosum remained separate. This separate spongiosum tissue is what allows echidnas to erect each half, or pair of heads, independently from the other, the researchers said.
How do echidnas survive cold winters?
Echidnas hibernate during the cold winter months in burrows. No matter what the time of the year, they can only enter REM sleep when they are around 77 F (25 C).

Are echidnas blind?
Eyesight is not a crucial factor in the animal's ability to survive, as blind echidnas are able to live healthily. Its ears are sensitive to low-frequency sound, which may be ideal for detecting sounds emitted by termites and ants underground.
How do echidnas use their long tongue?
They use their long, sticky tongues to feed on ants, termites, worms, and insect larvae. (The short-beaked echidna earned its scientific name, *Tachyglossus, *meaning "fast tongue," from its way of rapidly darting its 6-inch tongue in and out of its mouth to slurp up insects).
What is a group of echidnas called?
A PARADE of Echidnas A weird collective noun for a small, slow, spiky monotreme that dislikes public displays of emotion.
Do echidna spines hurt?
"We've seen the spines actually melted down to little nubs on the body." This might sound particularly painful, but Rismiller says not to worry too much, as it wouldn't hurt quite as badly as you might imagine. "The spines are modified hairs," she explained. "So, you know, they do grow back."
Are echidnas spines poisonous?
"A waxy secretion is produced around the base on the echidna spur, and we have shown that it is not venomous but is used for communicating during breeding," said Professor Kathy Belov, lead author of the study published in PLOS One today. Professor Belov is from the University's Faculty of Veterinary Science.
What is an echidna?
The echidna (ih-KID-na), or spiny anteater, is an unusual mammal. It is so different from any other that it still puzzles researchers and scientists. The echidna has remained unchanged since prehistoric times, finding ways to survive while other species became extinct.
What are the threats to echidnas?
Other than fires and drought, the main threats to the slow-moving echidna are feral dogs and cats as well as dingoes and foxes. Cars also kill hundreds of these animals each year on the roadways of Australia. The echidna has three options when faced with danger: run away on its short, stubby legs, dig, or curl up.
What do the nostrils on an echidna's beak do?
The nostrils at the tip of the beak help the echidna sniff out its next meal. The rubbery snout is also sensitive to electrical signals from an insect’s body. It is strong enough to break open hollow logs and plow up the forest floor in search of insects. An echidna’s typical day begins by finding something to eat.
How does an echidna use its tongue?
Once food is located, the echidna tears into the mound or nest with its large, sharp claws and then uses the 6-inch (15-centimeter) tongue to lap up the bugs or worms . Hard pads at the base of the tongue and on the roof of the mouth grind the food into a paste for swallowing.
How old is the echidna in the zoo?
He was believed to be at least 58 years old. An echidna is one of the Australian animals featured in the VIP animal ambassador area at Walkabout Australia, at the San Diego Zoo Safari Park.
What is an echidna's face called?
The echidna has a tiny face with small eyes and a long nose, sometimes called a beak.
Where do echidnas live?
Echidnas inhabit scrubland, desert, and montane forest in Australia, Tasmania, Indonesia, and Papua New Guinea. Digging for food and shelter is key, so areas with loose topsoil work well, though these animals can plow through hard-packed dirt as well.
How do echidnas protect themselves?
Due to their small size and slow speed, the echidna protects itself by either hiding, or curling into a ball being protected by their spikey exterior. In soft soils echidnas will sometimes bury themselves if the opportunity arises.
Where do echidnas live?
RANGE. found throughout Australia; echidnas have overlapping home ranges but tend to be solitary except for mating. home range of 50 hectares on average across different habitats. HABITAT. very adaptable. hot arid interior (Simpson Desert) to above the snow line in alpine regions.
Do echidnas have defensive weapons?
no defensive or offensive weapons. a threatened echidna pulls its head in and curls into a ball to protect its belly so that all that is presented is a ball of spines. in soft soil, it can also dig in and disappear rapidly climb into trees or climb fences.

Physical characteristics
- The echidna has a tiny face with small eyes and a long nose, sometimes called a beak. The eyes dont help the echidna see well, but its acute sense of hearing and smell give this unusual mammal the information it needs to know to survive. The short-beaked echidna has dark fur almost completely hidden by a covering of hollow, barbless quills, called spines, on its back and sides. L…
Conservation
- Digging in for protection. Other than fires and drought, the main threats to the slow-moving echidna are feral dogs and cats as well as dingoes and foxes. Cars also kill hundreds of these animals each year on the roadways of Australia. The echidna has three options when faced with danger: run away on its short, stubby legs, dig, or curl up.
Behaviour
- The echidnas digging ability is usually its best bet. Some say it can dig a hole just as fast as a human using a shovel can!

Diet
- An echidnas typical day begins by finding something to eat. Like anteaters, the echidna has no teeth. So how does it eat? The echidna has a long, sticky tongue to catch and chew its food: ants, termites, or earthworms. Once food is located, the echidna tears into the mound or nest with its large, sharp claws and then uses the 6-inch (15-centimeter) tongue to lap up the bugs or worms…
Reproduction
- Echidna breeding season is during July and August. An adult female echidna usually lays a single, leathery egg once a year. She rolls the newly laid egg, about the size of a grape, into a deep pocket, or pouch, on her belly to keep it safe. Ten days later, the baby echidna, called a puggle, hatches. It is smaller than a jelly bean! The puggle uses its tiny, see-through claws to grip the sp…
