Platypus & Echidna Order

Monotremata, represented by the platypus and echidnas, is an unusual order of mammals. The platypus and echidnas are unique among living mammals because they lay eggs instead of giving birth to live young. Like all other mammals, monotremes produce milk for their young, have fur, and are warm-blooded. The features of the platypus, also called duckbill, include a electromechanical system that allows it to navigate underwater; the males have venomous spurs on their hind legs. Echidnas, also known as spiny anteaters, are covered in protective spines, have a tubular beak, and use long sticky tongues to feed on ants, termites, and other invertebrates. The most ancient living order of mammals, they are only found in Australia, Tasmania, and New Guinea.
