Bats are placental mammals. Unlike monotremes, they do not lay eggs.
Monotremes, marsupials, and placentals
Because placentals are the largest number of mammals.
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.
Plato Users: Reproduction and Development (monotremes, placentals, etc.)
Yes. Dolphins are placental mammals because they do not have a pouch like most marsupials, and they do not lay eggs like the monotremes.
No. Mammals which lay eggs are monotremes. Placental mammals and marsupials give live birth.
Monotremes:Platypus and echidnaMarsupials:Kangaroo, koala, wombat, Tasmanian devil, possum, bilby, quoll, quokka, wallaby, dunnart, phascogale, bandicootPlacental mammals:Dog, cat, horse, antelope, camel, guinea-pig, mouse, pig, giraffe, elephant, bat, armadillo, cow
Theria is the closest connection between marsupials and placentals. It includes all mammals besides the monotremes.
yes all mammals are placental. No, not all animals are placentals. There are also marsupials and monotremes.
No. Monotremes are mammals which lay eggs rather than give birth. The only monotremes are the echidna and the platypus. Bats give live birth, so they are not monotremes.
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.
Placentals, 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.
