The platypus and the echidna are both monotremes, that is, egg-laying mammals. There are actually three known species of egg-laying mammals, or monotremes. They are the platypus and short-beaked echidna of Australia, and the long-beaked echidna of Papua New Guinea. The echidna is sometimes called the spiny anteater.
They are mammals because, like all mammals, they suckle their young on mothers' milk.
Most mammals do not hatch from eggs. However, there is a small group of egg-laying mammals which are known as monotremes.
There are just three known species of monotremes: the platypus; the short-beaked echidna; and the long-beaked echidna.
Which mammal lays the biggest egg?
The ostrich lays the biggest but most dinosaurs laid bigger eggs than that.
How do monotremes young develop?
Monotreme young are hatched from eggs. Unlike other mammals, they are not born live. They are still mammals because the mother nurtures her young with milk which she secretes from glands on her abdomen.
Monotremes are the egg-laying mammals, and there are just three species.
Platypuses and short-beaked echidnas are endemic to Australia. The long-beaked echidna is found in Papua New Guinea.
How are monotremes different from other mammals?
Monotremes are mammals.
Monotremes are unique types of mammals which lay eggs, rather than giving birth to live young. The only known monotremes are the platypus and the echidna, both of which are found in Australia, while echidnas are also found in New Guinea.)
What are examples of monotremes?
The only extant monotremes (mammals that lay eggs instead of producing by live birth) are the platypus and two species of echidna, the long-beaked echidna and the short-beaked echidna. Debate is still out on how many species of long-beaked echidna there are.
What kind of mammals lay amnionic eggs?
Monotremes lay amniotic eggs. Monotremes include just the platypus, the short-beaked echidna and the long-beaked echidna.
There are two mammals that lay amniotic eggs. The two mammals that lay amniotic eggs are echidna and platypus.
Do monotremes nourish their young?
Monotremes are egg laying mammals (Prototheria) instead of mammals which give birth to live young like marsupials (Metatheria) and placental mammals (Eutheria). They are still classified as mammals because they feed their young on mothers' milk.
Australia has two species of monotremes: the platypus and the short-beaked echidna.
The long-beaked echidna is the only other species of monotreme, and lives in New Guinea, as does a smaller population of short-beaked echidna.
The name monotreme is derived from two Greek words meaning "one-holed", because 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.
Montremes are from the class mammalia and include the spiny anteater and duck billed platypus. These mammals are able to lay eggs unlike marsupials whose young are born premature (ex. Kangaroo, oppossum, Tasmanian devil) and the placental mammals whose fetus's attached to placenta in uterus like in humans.
to my limited knowledge - i have only come across it once before - is a theoretical instrument somewhat like a guitar with only one string. i have also heard of it referred to as the monotrome of humanity or realty. Have seen a pic of it, but not sure where
How are monotremes and marsupials similar?
- Monotremes and marsupials are both orders within the classification of marsupials.
- Because monotremes and marsupials are mammals, they are warm-blooded vertebrates with skin, fur or hair, and breathe using lungs.
- Monotremes and marsupials, along with placental mammals, feed their young on mothers' milk.
- Monotremes and marsupials are both found primarily (but not exclusively) on the Australian continent.
Monotremes are egg-laying marsupials Name the only two monotremes in Australia?
The two monotremes, or egg-laying mammals, in Australia are the platypus
and the short-beaked echidna.
Yes. Both types of monotremes - platypuses and echidnas - have fur and lay eggs. In addition, echidnas have sharp spines, but these protrude from its body through a layer of thick fur.
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 monotremes urinate through their anus?
Eggs, urine and feces are all evacuated through the same oriface which is referred to as a cloaca.
Is a monotrome a mammal that lays eggs?
Correct. Egg-laying mammals are called monotremes. The only known monotremes are the platypus and short-beaked echidna of Australia and the long-beaked echidna of New Guinea.
This description fits the platypus.
What two mammals lay eggs in the south eastern US?
No mammals lay eggs in southeastern US.
The only two egg-laying mammals in existence are the platypus and the echidna, which are classed as 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.
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.
What organ do pregnant monotremes and marsupials lack?
A complex placenta. Marsupials have a choriovitelline placenta, but it is not as well-developed as the placentas of placental mammals.
The two egg laying mammals are native to which continent?
There are three known species of egg-laying mammals, or monotremes, but they are not all found on the same continent. They are the platypus and short-beaked echidna (Tachyglossus aculeatus) of Australia, and the long-beaked echidna (Zaglosssus bruijni) of the island of 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.
