Question

Some organisms, like the platypus, are difficult to classify as they have characteristics which fall into multiple categories. Which characteristics of a platypus would lead scientists to classify them as mammals?

Answer 1

they produce milk and they give birth to live young

Answer 2

Answer;

-They have glands that produce milk for their young and hair

Explanation;

-Mammals that lay eggs are called monotremes and include platypuses and echidnas, both of which live in Australia. Like all mammals, monotremes are warm-blooded, covered with fur and nurse their young.

-The platypus is classed as a mammal because it has fur and feeds its young with milk. It flaps a beaver-like tail. But it also has bird and reptile features; a duck-like bill and webbed feet, and lives mostly underwater. Males have venom-filled spurs on their heels.
