How do the short-beaked echidna reproduce?
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. The egg is oval and weighs between 1.5 and 2 grams. Once the egg has been laid, it remains in the female’s pouch for a further 10 days.
How often do echidnas reproduce?
Echidnas had 1 annual breeding period with courtship lasting 7–37 days. Females monitored were observed to mate only once per breeding season with 1 male. All females that mated produced a single fertile egg 23 days ± 1 SE after mating.
How many eggs do short-beaked echidnas lay?
one egg
Life history cycle. Like the Platypus, the Short-beaked Echidna is an egg-laying mammal or monotreme and lays one egg at a time. The eggs hatch after about 10 days and the young, emerge blind and hairless. Clinging to hairs inside the mother’s pouch, the young echidna suckles for two or three months.
How does an echidna breed?
During the breeding season a male echidna may join several separate trains. A female lays a single egg, which is incubated in the pouch and takes about ten days to hatch. The eggs are round to slightly oval in shape and 13–16 mm long, with a soft, leathery shell (Rismiller & Seymour 1991).
How do echidnas have babies?
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.
Do male echidnas lay eggs?
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.
How many babies do echidnas have at a time?
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.

What do short-beaked echidnas eat?
The Short-beaked echidna eats ants, termites, worms and grubs. Short-beaked echidnas are polygynous and in the breeding season a ‘train’ of a number of males may follow one female in the hope to mate with her.
How long do short-beaked echidnas live?
In the wild, the short-beaked echidna has an average lifespan of 10 years, though they can live as long as 40. The longest-lived specimen reached 49 years of age in a zoo in Philadelphia.
Do echidnas have territoriality?
Their movements do not depend on territoriality but on food availability. The Short-beaked echidna eats ants, termites, worms and grubs. Short-beaked echidnas are polygynous and in the breeding season a ‘train’ of a number of males may follow one female in the hope to mate with her.
How does a short-beaked echidna produce milk?
The spines of the Short-beaked echidna have tiny bundles of muscle connected to the bottom of each spine, enabling the echidna to control the spine’s direction and movement. Female echidnas secrete milk via two aerola patches: small, hairy areas connected to their milk glands.
