Monotremes

Monotremes, such as the platypus and echidna, are unique egg-laying mammals. The platypus has a streamlined body covered in waterproof fur, a flat bill, and webbed feet, which aid in swimming in rivers and streams. Echidnas have spiny coats and burrow in the ground, using their strong claws to dig. Both species move with a combination of waddling on land and swimming or digging, depending on their environment.

Monotremes, such as the platypus and echidna, exhibit a unique digestive process that reflects their evolutionary status as egg-laying mammals. They possess a cloaca, a single opening for excretion and reproduction, and their digestive system includes specialized adaptations for processing a diet primarily composed of insects, worms, and other small invertebrates. Monotremes have a relatively simple stomach and rely on gastrointestinal bacteria to help break down food, while the platypus also uses electroreception to locate prey in water. Overall, their digestion is efficient but adapted to their specific dietary needs and ecological niches.

Monotreme mammals include the echidna and the platypus. These unique mammals are characterized by their reproductive method, as they lay eggs rather than giving birth to live young. Monotremes are primarily found in Australia and New Guinea and are known for their distinctive features, such as the platypus's duck-bill and webbed feet. They represent one of the most primitive branches of mammals, providing insight into the evolution of this group.

Monotremes, such as the platypus and echidna, possess unique reproductive organs that include cloaca, which serves as a common opening for excretion and reproduction. Female monotremes have specialized mammary glands that produce milk, though they lack nipples; milk is secreted through openings in the skin and pools in grooves for the young to lap up. Males have testes that remain internal and do not descend into a scrotum, which is unlike most other mammals. Additionally, male monotremes have spurs on their hind limbs that can deliver venom.

Monotremes, like the platypus, lay eggs and nurse their young with milk after hatching. Marsupials, such as kangaroos, give birth to relatively undeveloped young that continue to grow and develop inside a pouch. In contrast, placental mammals, like humans, carry their young in the womb, where they receive nutrients and oxygen via a placenta until they are more fully developed at birth. These differences reflect various evolutionary adaptations to reproductive strategies and environments.

Almost all monotreme fossils have been found in Australia. An exception is the fossil of a platypus-like creature named Monotrematus sudamericanum found in Argentina, within a Patagonian rock formation.

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.

The reproductive system of a monotreme (such as the platypus or echidna) empties into a cloaca, which is a single opening for excretory, digestive, and reproductive functions. The cloaca is found in both male and female monotremes, serving as the common exit point for waste and reproductive fluids.

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.

One example of an animal that fertilizes its eggs in a similar way to humans is a chicken. Fertilization occurs internally when a rooster mates with a hen, and the sperm fertilizes the egg within the hen's reproductive tract.

The only three living species of monotremes are the platypus and two species of echidna (short-beaked echidna and the long-beaked echidna). Monotremes are egg-laying mammals found in Australia and New Guinea.

A monotreme is a type of mammal that lays eggs instead of giving birth to live young. The platypus and echidna are the only existing monotreme species. They are unique in the animal kingdom for their combination of reptilian and mammalian characteristics.

Monotremata is the scientific name for monotremes

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.
