Definition
A monotreme is a mammal that lays eggs instead of giving birth to live young, like most mammals. This makes them unique among mammals. Only a few species exist today, like the echidnas and platypuses of Australia and New Guinea. They possess a cloaca, a single opening for excretion and reproduction. Think of them as the weirdos of the mammal world – the odd ones out! 🤯 Monotremes nurse their young with milk, despite laying eggs.
