Monotremes (Platypus/ornithorhynchids and echidnas/tachyglossids) are mammals. Basal to the mammal lineage, they lay eggs.
The platypus spends ten days as an egg incubating within its mother, until the egg is laid. This is the first stage.
The soft-shelled egg is incubated by the mother curling around it and keeping it warm and dry in the chamber of the burrow for another 28 days. Once it is hatched, the platypus spends several more months with its mother until it is weaned. The mother lacks a pouch. The young platypus feeds on mother's milk which oozes through modified sweat glands of the platypus parent and does not emerge from a teat. The young platypus reaches reproductive maturity at around age 2, and may live to around 9-11 years. As an adult, the platypus then spends its life searching for aquatic invertebrates for food.
Unlike the platypus, the echidna does not lay its eggs in a burrow. After mating, there is a gestation period for the egg of 23 days. During breeding season, the female develops a rudimentary pouch which is really just a flap of skin. When it comes time to lay her egg, she curls tightly into a ball and lays it directly in this pouch, where it is incubated for around 10 days. The young emerge blind and hairless, and stay in the pouch, suckling for two to three months.
Once the baby echidna develops spines, the mother moves it into a burrow. It continues to suckle for the next six months, whilst also being introduced to ants and termites. As an adult, the echidna uses its strong claws to dig into termite nests for food. A highly adaptable creature, the echidna may be found in bushland, deserts, alpine areas and even suburban fringes.trundles around searching for ants and termites on the scrubland/forest floor. When they reach sexual maturity, they themselves will mate and lay eggs and raise young exactly as their parents did.

Do amphibians feed their young with milk?
No, amphibians do not feed their young with milk. Some amphibians lay eggs that the young, called tadpoles, hatch from and then develop on their own without parental care.
Is the grebes carnivore?
No. Grebes are not mammals - they are birds. The differences between birds and mammals are:Birds have feathers while mammals have fur, hair or skinBirds lay eggs whilst mammals (with the exception of the monotremes) bear live youngBirds do not feed their young on mothers' milk like all mammals do
What does a mother mammal make?
Mother mammals make milk for their offspring.
Are goldfinches omnivores?
No. Finches are not mammals - they are birds. The differences between birds and mammals are: Birds have feathers while mammals have fur, hair or skin Birds lay eggs whilst mammals (with the exception of the monotremes) bear live young Birds do not feed their young on mothers' milk like all mammals do
Are otters Monotremes?
No, otters are not monotremes. Monotremes are a group of egg-laying mammals that include the platypus and echidnas. Otters are classified as carnivorous mammals in the family Mustelidae, which also includes weasels, badgers, and martens.
Do monotremes feed their young milk?
Monotremes do not have nipples like most mammals, so the young can't suckle milk. Instead, monotremes have pores that ooze milk. The baby monotremes then lap up the milk.
Does an echidna feed its young milk?
Yes. Although echidnas are egg-laying mammals, known as monotremes, they are fully mammal. The defining characteristic of a mammal is to feed its young on mothers' milk.
What do echidnas feed their young?
Echidnas are mammals, despite being egg-laying mammals, or monotremes. Therefore, like all mammals, they feed their young on mothers' milk.
Is a monotreme also a mammal?
Yes. Monotremes are egg-laying mammals. they are mammals because they feed their young on mothers' milk.
What mammals lay eggs and feed their young on milk from the mother's pores?
These egg-laying mammals are known as monotremes. The group known as monotremes includes just the platypus and the echidna.
What are the four mammals that lay eggs and feed milk to their young ones?
The four mammals that lay eggs and feed milk to their young are known as monotremes. These include the platypus and three species of echidnas, also called spiny anteaters. Monotremes are unique among mammals for their reproductive method of laying eggs rather than giving birth to live young. They nurse their offspring with milk after hatching.
How are monotremes and marsupials the same?
Monotremes and marsupials are both mammals. They are warm-blooded vertebrates which have fur and breathe using lungs (instead of gills). As they are mammals, they both feed their young on mothers' milk.
Do all mammals feed from their mothers?
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.
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.
Is there any animal which lay eggs and also give milk?
Both the platypus and the echidna are egg-laying mammals. They belong to the group known as monotremes and, like all mammals, they feed their young on mothers' milk.
Do all mammals breastfeed their young?
No, not all mammals breastfeed their young. Some mammals, like monotremes (such as platypuses and echidnas), lay eggs and do not produce milk to feed their offspring.
Does a lyrebird feed its young milk?
Birds do not feed their young on milk. The lyrebird is a bird, so it does not feed its young milk.
