Neither.
Elephants are placental mammals, which form a different group of mammals from either the marsupials (pouched mammals) or the monotremes (egg-laying mammals).
Elephants are placental mammals. Marsupials have a pouch (which elephants don't) and monotremes lay eggs (which elephants CERTAINLY don't)
Monotremes, marsupials, and placental mammals.
Monotremes and marsupials are both types of mammals along with placental mammals
The majority of the world's marsupials and monotremes are found on the continent of Australia.
Marsupials give live birth to undeveloped young, which then crawl to the nipples (protected by a pouch in many species). Monotremes lay eggs and do not have nipples. Adult marsupials have teeth, but adult monotremes are toothless. Monotremes have interclavicle and coracoid bones in their shoulders, putting their legs to the sides of their bodies like reptiles. Marsupials do not. Monotremes have spurs on their ankles (venomous only for male platypuses), but marsupials do not.
Marsupials, monotremes and placental animals are members of the group known as mammals, or Mammalia.
Monotremes and marsupials are both orders within the classification of marsupials.Because monotremes and marsupials are mammals, they are warm-blooded vertebrates with skin, fur or hair, and breathe using lungs.Monotremes and marsupials, along with placental mammals, feed their young on mothers' milk.Monotremes and marsupials are both found primarily (but not exclusively) on the Australian continent.
Continental drift is a significant factor in why monotremes and most (not all) marsupials are found in Australia. This has resulted in isolation.
Monotremes, marsupials, and placentals
The platypus and the echidna are both Australian monotremes.
1.) Placentals2.) Marsupials 3.) Monotremes
Monotremes and marsupials are both mammals. They are warm-blooded vertebrates which have fur and breathe using lungs (instead of gills). As they are mammals, they both feed their young on mothers' milk.
