monotremes and marspials are both endotherms, vertebrates, and have fur or hair
Monotremes and marsupials are both types of mammals along with placental mammals
Monotremes, marsupials, and 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.
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
Neither. Elephants are placental mammals, which form a different group of mammals from either the marsupials (pouched mammals) or the monotremes (egg-laying mammals).
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.
The two monotremes, or egg-laying mammals, in Australia are the platypusand the short-beaked echidna.
