Echidnas are monotremes which means that they lay an egg instead of giving birth to live young. The egg remains in the female reproductive tract until it is about the size of a grape. ... Once the egg has been laid, it remains in the female's pouch for a further 10 days.

Do echidnas lay eggs or give birth?
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. The gestation period is quite quick – after only ten days the baby echidna hatches.
How often do echidnas reproduce?
If there is only one male, the mating ring becomes a simple straight trench. Ever versatile, echidnas can also mate below ground. On Kangaroo Island, Peggy Rismiller has found that females only breed every three to seven years and not until they're about five to seven years old.
Do echidnas have 4 headed penises?
But perhaps what is most bizarre about the echidna penis is that it has four heads, which are actually rosette-like glans at the end. Only two of these four glans ever become functional during erection and which glans are functional appears to alternate between subsequent erections.
How many babies do echidnas 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.
How many echidnas are left in the world 2021?
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. In New Guinea, chief threats to echidnas are hunting and farming. As human populations grow, so does our need for food.
Why do echidnas bury themselves?
An echidna that has dug its way into the ground as self-defence.
Do echidnas have a mating season?
Echidnas breed from the end of June to early September. A particular characteristic displayed by echidnas during the breeding season is the formation of 'trains' (Rismiller 1993).
How do echidna urinate?
Instead, echidnas use a cloaca — a multipurpose opening for urinating, defecating and, in females, egg laying. When not in use, echidnas' penises are retracted inside their bodies and emerge through the cloacal opening when erect; their testes, which unusually have no scrotum, remain inside their bodies all the time.
How do you tell if an echidna is male or female?
You can't tell if an echidna is male or female by simply looking at them as they have no gender-specific features and their reproductive organs are internal. All echidnas are born with spurs on their hind limbs, similar to what male platypuses have.
How do echidnas communicate?
Sydney researchers have discovered that male echidnas use the spur on their hind leg to communicate with their peers, quite unlike their close relative, the platypus, who use their leg spur as a weapon.
Are echidnas endangered 2021?
All are Critically Endangered (IUCN).
Do echidnas make a noise?
Did you know a baby echidna is called a puggle? Or that adult echidnas make 'snuffling' noises when they hunt for food? There's a lot to like about the Short-beaked Echidna. This waddling, well-camouflaged mammal is a very peculiar creature.
What do echidna eggs look like?
After mating, a female echidna lays a single, soft-shelled, leathery egg, about the size of a dime, into her pouch. Ten days later, the baby echidna (called a puggle and smaller than a jelly bean) hatches.
Is echidna and porcupine the same?
Although people commonly use the term 'porcupine' for our echidnas, they are definitely not the same animal. Although they are both spiny, echidnas don't release their spines to defend themselves as do porcupines.
