The platypus is a notable and unusual example of which small group of mammals that lay eggs rather than giving birth to live young?

Explanation

The platypus belongs to a small and unusual group of mammals called monotremes, which lay eggs rather than giving birth to live young, setting them apart from the vast majority of other mammal species. Despite this egg-laying trait more typically associated with reptiles or birds, monotremes still share the defining mammalian characteristics of having fur and producing milk to nourish their young after hatching. Along with the platypus, a small number of echidna species are the only other living monotremes, and both are found only in Australia and New Guinea.
