The scientific name for monotremes is Monotremata. This group of mammals includes the platypus and echidnas, which are unique because they lay eggs instead of giving birth to live young.

The only mammals that reproduce by laying eggs are the monotremes, and these include just the echidna and the platypus.

The platypus and the short-beaked echidna are native to Australia. There are two species of echidna: the long-beaked echidna and the short beaked echidna, both of which are found in New Guinea.

Actually, not all animals that lay eggs are mammals, and not all mammals give live birth. Some snakes have livebirth(reptile), and the platapus(mammal), lays eggs. But, to answer your question, animal that lay eggs are called reptiles, amphibeans, fish, and birds.

Female monotremes are the only mammals which do not have nipples for the young mammals to suckle from. Monotremes, which are the echidnas and platypuses, feed their young on mothers' milk which is exuded from modified sweat glands, rather than from well-formed teats.

Female monotremes also do not have two external openings. They have just one external opening, the cloaca, for both waste elimination and for reproduction. The cloaca leads to the urinary, faecal and reproductive tracks, all of which join internally, and it is the orifice by which the female monotreme lays her eggs.

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.

There are just three species of monotreme: the platypus, the short-beaked echidna and the long-beaked echidna. Of the three species, the long-beaked echidna is the largest.

There is no such thing as a bird that is a mammal. Mammals are one classification, and birds are another. All birds lay eggs. Most mammals do not lay eggs. The only exceptions are the monotremes, which include just the platypus and the echidna.

Nope - Tarsiers are mammals.

No, birds are strictly avians. Mammals that lay eggs are considered monotremes.

Egg-laying mammals are called monotremes. However, the belief that they are more primitive than other mammals is a fallacy, and an outdated belief. Scientists no longer regard monotremes as "primitive" mammals.

The classification of monotremes is as follows:

Kingdom: Animalia

Phylum: Chordata

Subphylum: Vertebrata

Class: Mammalia

Subclass: Prototheria

Order: Monotremata

Because placentals are the largest number of mammals.

There are just three species of monotremes, or egg-laying mammals.

The natural environment of platypuses and short-beaked echidnas is located in Australia. The long-beaked echidna is found in Papua New Guinea.

No mammal lays eggs in the water.

The platypus and echidna are both egg-laying mammals, and the platypus digs a burrow with a chamber in a riverbank or beside a pond or creek. However, the eggs are meticulously kept dry at all times.

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.

Egg laying mammals are the mammals classified as monotremes. These include the Platypus and various species of Echidna.

Monotremes are the only egg-laying mammals. They are fully mammal because they feed their young on mothers' milk.

Marsupials are the only mammals to give birth to undeveloped young after a short gestation period. These young are unable to exist independently of their mothers' nourishing teats, and for the most part, they are protected by a pouch, or marsupium - although this is not the case with all marsupials.

Monotremes are the only type of mammals which lay eggs.

Monotremes include the platypus, the short-beaked echidna (both found in Australia) and the long-beaked echidna, which is endemic to New Guinea.
