Marsupials, monotremes and placental mammals are all mammals. They share the following characteristics: * vertebrates * warm-blooded * have fur, skin or hair * breathe through lungs (not gills) * the young feed on mother's milk The major differences, however, include: * monotremes are the only mammals which lay eggs * marsupial young are born undeveloped and continue most of their growth and development whilst they are in the mother's pouch, attached firmly to the teat for several months, where they receive all their nutrients.

∙ 12y agoPlacentals, marsupials and monotremes are all types of mammals. Therefore, the main thing which they all have in common is that they all feed their young on mothers' milk.
In addition, they are all warm blooded vertebrates with a covering of fur, skin or hair. They all have four-chambered hearts, and full circulatory, respiratory and digestive systems. They all have a flexible neck with seven cervical vertebrae, and show enhanced neocortex development. Their limbs are oriented vertically and they produce sound via the larynx.

∙ 11y agoBoth placental mammals and marsupials give birth to live young (unlike monotremes, which are egg-laying mammals). Being mammals, they both feed their young on mothers' milk. They have a covering of skin or fur, and are warm-blooded. They breathe using lungs, and they have a four-chambered heart.

What 3 examples of mammals are there?
Monotremes, marsupials, and placentals
Why are plancetals more successful than marsupials and monotremes?
Because placentals are the largest number of mammals.
Is a gorilla a placental or monotremes?
Marsupials, monotremes, and placentals are all types of mammals. To qualify as a mammal, an animal has to be warm blooded, have hair, and produce milk for its young. Alligators do not fit any of those criteria, because they are reptiles, not mammals. So they are not marsupials, monotremes, or placentals.
Are mammals that lay eggs called placentals?
No. Mammals which lay eggs are monotremes. Placental mammals and marsupials give live birth.
Are dolphins placentals?
Yes. Dolphins are placental mammals because they do not have a pouch like most marsupials, and they do not lay eggs like the monotremes.
What MOST SPECIFIC classification puts humans in the same category as whales?
Theria is the closest connection between marsupials and placentals. It includes all mammals besides the monotremes.
Are zebra's placental mammals?
yes all mammals are placental. No, not all animals are placentals. There are also marsupials and monotremes.
What happens when marsupials and placentals came into contact?
the two groups mixed together with minimal competition due to their niche differences
Do all mammals feed from their mothers?
Yes. The fact that these animals feed their young on mothers' milk is one of the defining characteristics of all mammals, including the placentals, marsupials and monotremes.
Is a bat a monotremes or a placentals?
Bats are placental mammals. Unlike monotremes, they do not lay eggs.
Are chiropterans placentals marsupials or monotremes?
Marsupials, monotremes and placental mammals are all sub-groups of mammals. They share the following characteristics:vertebrateswarm-bloodedhave fur, skin or hairbreathe through lungs (not gills)the young feed on mother's milkThe major differences, however, include:monotremes are the only mammals which lay eggsmarsupial young are born undeveloped and continue most of their growth and development whilst they are in the mother's pouch, attached firmly to the teat for several months, where they receive all their nutrients.
What are two mammals that are not placental mammals?
The echidna and the platypus are non-placental mammals. They are monotremes, or egg-laying mammals. Kangaroos, wallabies, koalas, bandicoots, wombats and Tasmanian devils are just a few other non-placentals, as they are marsupials.
