No, birds are strictly avians. Mammals that lay eggs are considered monotremes.
Name of the mammal that lays eggs and has scales?
There is no mammal which lays eggs and has scales.
The only egg laying mammals, or monotremes, are the platypus and the echidna. The platypus has fur, and the echidna has fur and sharp spines.
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 However, the belief that they are more primitive than other mammals is a fallacy, and an outdated belief.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.
What kind of creature is monotreme?
The classification of monotremes is as follows:
Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Mammalia
Subclass: Prototheria
Order: Monotremata
Why are plancetals more successful than marsupials and monotremes?
Because placentals are the largest number of mammals.
Where do monotremes originate from?
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.
What about what was the mammal that lays eggs?
The only egg-laying mammals are those in the order Monotremata.
There are just three species of animal in this order, and they are the platypus, short-beaked echidna (both of Australia) and the long-beaked echidna (found in New Guinea).
What are the features of the mammals that lay eggs?
Egg-laying mammals are known as monotremes, and they include the platypus and the echidna. Their characteristics are:
- unlike placental mammals and marsupials, they do not give live birth, but lay eggs in order to reproduce
- monotremes nurture their young with mothers' milk as all mammals do
- they have four limbs
- they are warm-blooded vertebrates
- they have a four-chambered heart
What is a mammal that spends much of its time in water and lays eggs?
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.
What are the similarities and differences between marsupials monotremes and placentals?
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.
Name one mammal which lays eggs?
Egg laying mammals are the mammals classified as monotremes. These include the Platypus and various species of Echidna.
What is unusual about the method of reproduction in monotremes in mammals?
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.
Which type of mammal lays eggs?
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.
What is a mammal that lays eggs and is herbivore?
No. Carnivores are meat-eating animals that hunt or prey on other animals. Lions are carnivores that are mammals but do not lay eggs.
Egg-laying mammals are called monotremes. The only monotremes are the platypus and the two species of echidna.
Are monotremes endothermic or ectothermic?
Monotremes, such as the echidna and the platypus, are endothermic. Monotremes are mammals, and all mammals are endothermic. This means that they regulate their body temperature by internal processes and that their body temperature is constant.
What is the correct name for an egg-laying mammal?
Egg-laying mammals are known as monotremes. They are of the Order monotremata.
There are three species of egg-laying mammals, or monotremes. They are the platypus, the short-beaked echidna and the long-beaked echidna.
Is a monotreme a mammal that lays eggs?
Yes,monotremes are mammals that lay eggs.They are special that there are only two kinds of monotremes.They are Echidna and Platypus.They both have mammary gland and fur or hair on their body.
The only mammals which breed by laying eggs are the monotremes, which include just the platypus and the echidna.
But for conception, an egg (ovum) and sperm are required in mammal reproduction. That is a different stage of egg (unfertilized) from the egg laid externally by animals.
All three species of monotremes, which comprise the platypus, short-beaked echidna and long-beaked echidna, reproduce sexually. Monotremes are egg-laying mammals, so platypuses and echidnas lay eggs in order to reproduce.
What is it called when an animal lays eggs rather than gives live birth?
It is called oviparity. Animals which exhibit this behaviour are known as oviparous.
What mammals are born from eggs?
There are two egg-laying mammals. The platypus and the echidna are both egg-laying mammals, or monotremes. They are still classified as mammals because they feed their young on mothers' milk - a characteristic unique to mammals alone.
There are just three known species of egg-laying mammals, or monotremes. They are the platypus and short-beaked echidna (Tachyglossus aculeatus) of Australia, and the long-beaked echidna (Zaglosssus bruijni) of Papua New Guinea. The echidna is sometimes called the spiny anteater, and there are several sub-species of the long-beaked echidna: the Western long-beaked echidna, Sir David's long-beaked echidna and the Eastern long-beaked echidna.
Do mammals give live births or do they lay eggs?
By definition, mammals have live young, with the exception of the three species of monotremes.
These include the platypus and the short-beaked echidna, native to Australia, and the long-beaked echidna, native to New Guinea. These animals lay eggs, but still feed their young on mother's milk.
Eutheria (placental mammals) and marsupials do not lay eggs.
Some mammals lay eggs but some give birth to young alive.
What are 2 names of the monotremes?
All monotremes lay eggs. That is their classification - egg-laying mammals. There are only 2 animals that are monotremes, the platypus and the echidna. There are, however, 2 different species of echidna.
Yes. Monotremes are the egg-laying mammals, which include just platypuses and echidnas.
Which mammals reproduce by laying eggs?
Mammals do not generally lay eggs. Almost all types of mammals give live birth.
There are three species of egg-laying mammals: the platypus, the short-beaked echidna and the long-beaked echidna. All three of these monotremes, or egg-laying mammals, lay their eggs on land. The platypus digs a burrow in a riverbank or creekbank, above the waterline, while the echidna lays her egg directly into a flap of skin that acts as a pouch.
