∙ 11y agoThere are three species of monotremes: the platypus, the long-beaked echidna and the short-beaked echidna.
The platypus has been known to live up to 16 years in captivity. Little research has been done on them in the wild, because they are very reclusive creatures. However, their lifespan in the wild is believed to be about 10 years. It is estimated that, due to predation by goannas and snakes, platypuses in their natural habitat probably live closer to 4-5 years for males and 6-8 years for females.
The short-beaked echidna has a lifespan of between 45 and 55 years. In the wild, due to predation and being hit by cars, their life span may average around 16 years. The long-beaked echidna, found only on the island of New Guinea, is believed to live for around 20 years.
