Monotremes are only found in either Australia or New Guinea.
Do snakes lay eggs?
The reason that odd, egg-laying mammals still exist today may be because their ancestors took to the water, scientists now suggest. The egg-laying mammals — the monotremes, including the platypus and spiny anteaters — are eccentric relatives to the rest of mammals, which bear live young.
Do sharks lay eggs?
You might have learned in school that reptiles are different from mammals because they lay eggs. While approximately 70% of snakes lay eggs, others don't. Snakes living in especially colder climates have live births because the eggs wouldn't survive outside.

Do dolphins lay eggs?
Given that monotremes, most reptiles, and all birds are oviparous, the common ancestor of mammals is thought to have been an egg-layer as well. This primitive mode of birth was retained in living monotremes, but evolved into live birth in the common ancestor of placentals and marsupials.
How many mammals still lay eggs?
Other characteristics of dolphins that make them mammals rather than fish are that they give birth to live young rather than laying eggs and they feed their young with milk.
