The Echidna: A Spiky, Egg-Laying Monotreme Like No Other

Short-beaked echidna


The Short-beaked echidna is a fascinating and unique animal that is native to Australia. With its spiny exterior and long, slender snout, it is a creature unlike any other. It is the most common and widely distributed species of echidna, and it is found throughout much of Australia and New Guinea. It is known for its short, sharp spines and its long, slender snout, which it uses for digging for food. The short-beaked echidna feeds primarily on ants and termites, and it has a highly specialized tongue that it uses to extract insects from their nests.

Scientifically known as Tachyglossidae, the echidna is a member of the monotreme family, which also includes the platypus. These animals are known for their ability to lay eggs, making them the only creatures in the world to do so.

The word “echidna” (pronounced e-kid-nas) is thought to be of Greek origin, derived from the word “echis,” which means “viper” or “adder.” This likely refers to the animal’s spiny exterior, which is reminiscent of the scales of a snake. The word “echidna” was first used to describe the animal in scientific literature in the early 19th century, and it has been used consistently ever since.

The echidna is also known by a number of other names in different parts of the world, including “spiny anteater” and “porcupine ant-eater.” These names are often used to describe the animal’s appearance and its diet, as it feeds primarily on insects and other small invertebrates.

With their sharp spines and long tube-like muzzles, echidnas look very different from their relatives the platypuses. Echidnas are quite small, typically measuring between 15 and 45 centimeters in length and weighing between 2 and 5 kilograms. They are covered in spines, which are used for protection against predators. The echidna’s long snout is used for probing in and out, as it feeds primarily on insects such as termites, ants and other small invertebrates.


Echidnas are found in a variety of habitats throughout Australia, including forests, grasslands, and deserts. They are generally found in areas with a reliable food source and plenty of shelter.


When it comes to reproduction, echidnas are known for their unique mating habits. During the breeding season, male echidnas will compete for the attention of females by producing a clicking noise and secreting a pheromone. Once a female has chosen a mate, the male will use his sharp claws to dig a nest for her to lay her eggs in. The female will then lay a single soft-shelled egg, which she will incubate in a pouch on her belly, which only forms in the breading season, until it hatches.

The puggle will feed on milk produced by the mother, which is secreted through her skin. The milk is high in fat and protein, and it helps the puggle grow and develop quickly. After several months, the puggle will emerge from the pouch and begin to explore its surroundings on its own.

Once the puggle is old enough to be independent, it will leave its mother and set out on its own. From this point on, the mother has no further role in the puggle’s care and development. Echidnas are generally solitary animals, and they do not form strong social bonds or live in family groups like some other animals do.

Overall, the mother and puggle relationship in echidnas is relatively short-lived, with the mother providing the necessary nutrients and care during the early stages of the puggle’s development before it sets out on its own.


Echidnas are generally solitary animals, only coming together to mate. Unlike most small mammals they are mostly active foraging during the day, probing with it’s long sticky tongue. When threatened, echidnas will curl into a ball, using their spines to protect themselves.

Conservation Status

Despite their tough exterior, echidnas are actually quite vulnerable to habitat loss and other threats. In some parts of Australia, they are at risk of being hit by vehicles as they cross roads in search of food. They are also threatened by habitat destruction, as their natural habitats are increasingly being lost to development.

To help protect these amazing animals, conservation efforts are being undertaken throughout Australia. These efforts include habitat restoration, education campaigns, and research into the echidna’s biology and behavior. By working together, we can ensure that these unique and fascinating creatures are around for generations to come.

So the next time you come across an echidna in the wild, take a moment to appreciate this amazing animal and all that it has to offer. The echidna is truly a marvel of nature, and one that we should all work to protect.
