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.

Etymology

The word 'monotreme' comes from the Greek words 'monos' meaning 'single' and 'trema' meaning 'hole' or 'opening.' This refers to their cloaca. The term was first used in the early 19th century. It reflects their unique anatomy. This anatomical feature sets them apart from other mammals with separate openings.
