How big was the giant echidna?
This giant extinct echidna weighed about 30 kg and stood around one metre tall (about the size of a sheep) making it the largest monotreme (egg laying mammal) to have ever lived. Just like today's echidnas, Zaglossus were covered in spines for protection.
When did Zaglossus hacketti go extinct?
It is thought that Zaglossus hackettii became extinct around 55,000 years ago, at around the same time as many of Australia's other Pleistocene beasts.
Do echidnas have quills?
Echidna Quills
In reality, they are in the order Monotremata, an ancient lineage of egg-laying mammals that contains only five living species: four species of echidna and the platypus. Of all of the spiny mammals, the quills of the echidna are perhaps the least studied.
Do echidna have teeth?
At the end of their slender snouts, echidnas have tiny mouths and toothless jaws. They use their long, sticky tongues to feed on ants, termites, worms, and insect larvae. ... Since they have no teeth, echidnas break their food down with hard pads located on the roof of the mouth and back of the tongue.
How many babies does an echidna have?
A female usually lays one egg at a time. The egg goes into a pouch on her stomach to incubate. After seven to 10 days, the egg is ready to hatch, according to the Animal Diversity Web.
Who killed echidna?
Although for Hesiod Echidna was immortal and ageless, according to Apollodorus Echidna continued to prey on the unfortunate "passers-by" until she was finally killed, while she slept, by Argus Panoptes, the hundred-eyed giant who served Hera.
How many long-beaked echidnas are left in the world?
bruijnii is Critically Endangered, and the population is decreasing. The eastern long-beaked echidna Z. bartoni is recognized as Vulnerable. Although there are estimated to be as many as 10,000 mature individuals, the population is decreasing, and this species is extinct in some parts of its former range.
Where does long-beaked echidna live?
Long-nosed echidnas primarily inhabitate mountain forests, although some live on highly elevated alpine meadows. The species does not live along the coastal plains (Augee, 1993; Walker, 1991).
Why is the short-beaked echidna endangered?
The Kangaroo Island short-beaked echidna has recently listed as endangered under the EPBC Act. Local threats included predation by feral cats, habitat loss and fragmentation, road mortality, predation by feral pigs and some reports of deaths due to electric fences.

Do male echidnas lay eggs?
5. They lay eggs. Along with the platypus, the echidna is the only other living egg-laying mammal species. Almost a month after mating, the female deposits a single, soft-shelled, leathery egg into her pouch.
How did the giant kangaroo become extinct?
Extinction. The genus was present until at least about 45,000 years ago before going extinct, although some evidence indicates it may have survived to as recently as 18,000 years ago. Its extinction may have been due to climate shifts during the Pleistocene, or to human hunting.
