Echidna comp

The echidna is a very special mammal and, along with the platypus, the echidna is the only other egg-laying mammal in the world. The echidna lays eggs that have a soft shell and are kept in the pouch of the female echidna until the eggs hatch in a couple of weeks. The young echidna remains in the pouch of the female echidna for around 50 weeks, when the baby echidna has grown spikes. The mother echidna then transfers the young echidna to a nursery burrow and returns every few days to feed the baby until it is around seven months old.
