What group of vertebrates gives birth to live young?
MammalsAll mammals feed their young on mothers' milk, but there is one group of mammals known as monotremes which actually lay eggs. The platypus and echidna are both egg-laying mammals.
Do platypus breastfeed?
Neither the male nor the female really sweats milk. The female produces milk for her young, but all mammals' mammary glands are just modified sweat glands. The difference is that female platypuses exude milk from several glands over their abdomen and since they do not have teats, the young have to drink it from the grooves into which it collects.
Does every mammal give birth to live young?
All mammals on earth give birth to their young instead of laying eggs. however the Duck-billed platypus from Australia is the only exeption to this, as it is the only mammal on earth that lays eggs instead of giving birth.
Does a platypus have nipples?
No, a platypus does not have nipples. Instead, female platypuses secrete milk from mammary glands through openings in their skin, allowing the milk to pool in grooves on their abdomen for the young to lap up. This unique method of nursing is one of the many distinctive traits of this egg-laying mammal.
What mammals do not give milk to their babies?
There are three groups of mammals, and all of them are suckled on mothers' milk. Feeds their young with milk is the one of the defining characteristics of mammals. No other anal group does this. Marsupials, monotremes and placentals are the the types of mammals. Each of these groups of mammals give milk to their young, but monotremes (platypuses and echidnas) produce milk through other glands, not from the teat.
Why do people think that a dolphin is classified as a fish and why a platypus isn't a reptile or a bird?
Both the dolphin and platypus are mammals for one very simple reason: they both suckle their young on mothers' milk. this is one of the defining charactersitics of mammals.because dolphins spend all their time in the water, it is difficult to conceive that it is a mammal, and that it could suckle its young on mothers' milk. And the platypus is often wrongly thought of as a reptile or a bird because it lays eggs. Its misnomer "duckbilled platypus" has a large part to play, too. Its bill is a different shape and has a very different function to that of a duck.
When the platypus is born do its parents take care of it?
Platypuses are not born; they are hatched, as the platypus is one of just two types of egg-laying mammals. The female platypus takes very good care of its young for several months until they are weaned. The young sometimes stay with the mother as a family group until the next breeding season.
How long is a platipus pregnant?
A platypus is not pregnant in the traditional sense, as it is one of the few mammals that lay eggs. After mating, the female platypus will lay one to three eggs, which she incubates for about ten days before they hatch. The young are then fed with milk from the mother until they are ready to fend for themselves.
What are the two hallmarks of mammals?
They have fur and fee their young milk. Humans are mammals.
Pictures of mammals that do not suckle their young?
All mammals suckle their young. That is one of the defining characteristics that makes them mammals. Even egg-laying mammals (monotremes which include the platypus and echidna) suckle their young.
Why was the platypus hard to classify?
The platypus is not difficult to classify: it possesses the defining characteristic of mammals, which is nurturing the young with mothers' milk. It has all other characteristics of mammals, such as breathing through lungs, having fur on its body, and having a four-chambered heart. The only way it differs from mammals is that it happens to lay eggs. This is not so unusual, given that no other vertebrate group (except for birds) has only one method of reproduction.
Do sheeps lay eggs?
Sheep are mammals and mammals do not lay eggs with one exception, the monotremes, of which the Platypus is an example.
