Reproduction

__How does a platypus reproduce?__
The Platypus reproduces sexually, and it is the only mammal on earth that lays eggs. The eggs are leathery like a reptile's eggs.

The platypus can breed anytime from 2 years old to 9 years old. The newly hatched young are vulnerable, blind, and hairless, and are fed by the mother's milk.

While the platypus female is holding the eggs, she builds a more elaborate burrow deeper in the ground, to protect the young from any predators, since they are so weak when born.
