Echidna is one of two animal that is a Monotreme. A Momotreme its a type of mammals that lays eggs. The only other Monotreme in the world is the platypus.

The male Echidna has a four-headed penis, and a female Echidna has one hole y mate the male echidna penis uses the two middle penis heads and does not use the other two. The eggs gets fertilized when the male sperm enters the cloaca of the female. The cloaca is the opening of the urinal, reproductive system and the digestive system. After the egg gest fertilized inside the body the mother lays the eggs 12 - 20 weeks later. During this time the embyo gets developed inside the mother. In ten days after the mother lays the eggs it hatches.

About 200 gamete is released during this progress. This is good because most likely the egg will get fertilised, but it will be also wast of lots of gamete because at the end it only uses one.


The process of embryo development happens internally. The echidna lay eggs witch mean it is a oviparous.

In the burrow the puggle can drink about 40 present of its weight. When seven mouth past the puggle comes out of the burrow and left to live on its own. The mother after that leaves and ignore the Echidna.
