The Quiz: Which mammal is known for laying eggs?
Alpaca
Fruit bats
Echidna
Honey badger
Mammals that lay eggs are known as monotremes, and there are only five species in the world that do so: four echidna species and one type of platypus. An adult female echidna generally lays a single, leathery egg once per year, which she places in a belly pouch for safekeeping. Ten days after the egg is laid, the baby echidna (known as a puggle) hatches.
The correct answer to this quiz is Echidna.
