monotreme mon·o·treme. The most primitive type of living mammal. Monotremes lay eggs, and the females have no teats but provide milk directly through the skin to their young. Monotremes include only the duck-billed platypus, found in Australia and New Guinea, and the echidnas, found only in New Guinea. Noun.

Monotreme The Platypus, the most well known monotreme. Monotremes are a group of mammals that form the order Monotremata. Monotremes are the only mammals that lay eggs, but they also feed their babies with milk. The word 'monotreme' refers to their common rear opening, the cloaca. In amphibia, reptiles, birds and probably all early tetrapods, there is a common opening for urine, reproduction and faeces.

What's a Monotreme? A monotreme is a rare sort of mammal found in Australia, Tasmania and New Guinea. The reason they are so rare is that they lay eggs! This group includes the Platypus and the Echidna (spiny anteater). The platypus is a semi-aquatic creature with webbed feet, a bill (sort of like a duck), waterproof fur and a flat tail (like a beaver). They are between 1 and 2 feet long and between 3 or 4 pounds.

Which Types of Animals Are Monotremes? Monotremes (Monotremata) are a unique group of mammals that lay eggs instead of giving birth to live young like other mammals (such as placental mammals and marsupials). Monotremes include several species of echidnas and the platypus.

Monotremata monotremes Like the eggs of birds, monotreme eggs are incubated and hatched outside the body of the mother. Incubation lasts about 12 days. The young, which are tiny and at a very early stage of development when they hatch, break out of the eggs using a milk tooth.

- A multimeter or a multitester, also known as a VOM (Volt-Ohm meter or Volt-Ohm-milliammeter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter would include basic features such as the ability to measure voltage, current, and resistance.

What are monotremes? 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.

- In chemistry, an oligomer (/əˈlɪɡəmər/ ( listen)) (oligo-, a few + -mer, parts) is a molecular complex that consists of a few monomer units, in contrast to a polymer, where the number of monomers is, in principle, unlimited.

Mononeuritis Multiplex Mononeuritis multiplex, also known as mononeuropathy multiplex or multifocal neuropathy, is a type of peripheral neuropathy. It happens when there is damage to two or more different nerve areas. Mononeuritis multiplex is actually a group of symptoms rather than its own disease. Its symptoms include numbness, tingling, abnormal sensation, lack of sensation, difficulty to control movement, or an inability to move a part of the body.

- Monotremes-Egg-laying Mammals. The duck-billed platypus is a monotreme which are a subfamily of mammals. They feed their young with milk, but instead of suckling from a teat, the milk simply oozes from glands under the skin, and is lapped up from a patch of fur.ther than the duck-billed platypus, there is only one other monotreme living today; a small spiny anteater called an Echidna. Monotremes, like most of the marsupials on earth are found exclusively in Australia. The platypus also possesses a number of other specializations many of which are unique to the platypi.

Platypus You have the platypus, a monotreme (an egg-laying mammal) that is indigenous to freshwater rivers and lakes in eastern Australia and Tasmania. Roughly the size of a house cat, the platypus is between 30-60 cm (12-24 in.) in length and weighs 1-2 kg (2-4 lb.).

Monotremes Monotremes lay eggs. However, the egg is retained for some time within the mother, which actively provides the egg with nutrients, and generally hatches soon after birth, within the span of 10 days (as opposed to eggs of sauropsids, which generally take much longer to incubate).

Monotremes There are only five living monotreme species: the duck-billed platypus and four species of echidna (also known as spiny anteaters). All of them are found only in Australia and New Guinea. Monotremes are not a very diverse group today, and there has not been much fossil information known until rather recently. In some ways, monotremes are very primitive for mammals because, like reptiles and birds, they lay eggs rather than having live birth. In a number of other respects, monotremes are rather derived, having highly modified snouts or beaks, and modern adult monotremes have no teeth. Like other mammals, however, monotremes have a single bone in their lower jaw, three middle ear bones, high metabolic rates, hair, and they produce milk to nourish the young.

Monotremata monotremes The skulls of monotremes are almost birdlike in appearance, with a long rostrum and smooth external appearance. Modern monotremes lack teeth as adults; sutures are hard to see; the rostrum is elongate, beak-like, and covered by a leathery sheath; and lacrimal bones are absent.

- Egg-laying mammals are called monotremes. There are only three monotremes in the world: the long-beaked echidna, short-beaked echidna, and duck-billed platypus. The taxonomic family name for echidnas, Tachyglossidae, means “fast tongue.” Both male and female echidnas have a pouch on the belly, making it difficult to tell one from the other.

Mononymous person Plato, the Greek philosopher, is universally known by a single name. A mononymous person is an individual who is known and addressed by a mononym, or single name. In some cases, that name has been selected by the individual, who may have originally been given a polynym (multiple name). In other cases, it has been determined by the custom of the country or by some interested segment. In the case of historical figures, it may be the only one of the individual's names that has survived and is still known today.

Monoplegia Monoplegia is a form of paralysis that affects just one limb. It is almost always the product of cerebral palsy. Monoplegia is a form of paralysis that affects just one limb. It is almost always the product of cerebral palsy, though a limited number of other medical conditions may cause monoplegia. Because monoplegia is rare, it is still poorly understood, and research into ideal treatments, the progression of the disease, and best practices for assisting patients is still in its infancy.

Hectometre Look up hectometre in Wiktionary, the free dictionary. The hectometre (International spelling as used by the International Bureau of Weights and Measures; SI symbol: hm) or hectometer (American spelling) is an uncommonly used unit of length in the metric system, equal to one hundred metres. It derives from the Greek word ekato, meaning hundred. A soccer field is approximately 1 hectometre in length. The hectare (ha), a common metric unit for land area, is equal to one square hectometre (hm2).
