GeneralClass 12AllAnswered 27 Mar 2026
Answer
The two primary examples of egg-laying mammals (monotremes) are:
- Platypus (Ornithorhynchus anatinus) - A semi-aquatic mammal native to eastern Australia with a duck-like bill, beaver tail, and venomous spurs
- Echidna (Tachyglossus aculeatus) - Also called spiny anteaters, found in Australia and New Guinea
These remarkable mammals represent the most primitive living mammalian group, combining reptilian characteristics (egg-laying, cloaca) with mammalian features (fur, milk production). Despite laying eggs, monotremes nurse their young with milk, fulfilling the mammalian classification criteria.
