Egg-laying Mammals This animal may have sharp spines, but it isn't a porcupine! It's one of two types of primitive egg-laying mammals, or monotremes. (The other is the duck-billed platypus.).

Duck-billed Platypus Together with the four species of echidna, the Duck-billed Platypus is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving birth to live young. After an egg hatches, the tiny baby (called a puggle) drinks its mothers milk, which comes from tiny openings in the mothers belly.

Difference between solute and solvent? a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is dissolved in another substance, known as a solvent. A common example is a solid, such as salt or sugar, dissolved in water, a liquid. Gases may dissolve in liquids, for example, carbon dioxide or oxygen in water.

- The monotremes are a group of highly specialised egg-laying predatory mammals, containing the platypus and echidnas. There are only five living species of monotreme, contained within two families: 1  Family Ornithorhynchidae: the platypus, a single species in a single genus, Ornithorhynchus anatinus.

The amazing platypus, the egg-laying mammal The amazing platypus, the egg-laying mammal. The platypus is one of the most fascinating species on our planet. Not only because this mammal lays eggs, is venomous and has a bill like a duck, but because it is the most evolutionary distinct mammal that exist today. A beautiful photo of a swimming platypus.

Platypus Facts Most mammals give birth to live young. Platypuses, however, lay eggs. They are a species of primitive mammals called monotremes. Echidnas, or spiny anteaters, are the only other mammals that lay eggs.When the female platypus is ready to have her young, she will burrow down inside the ground on the riverbank and seal herself into one of her tunnel rooms.latypuses (which is the correct plural form, not platypi) have a paddle-shaped tail like a beaver; a sleek, furry body like an otter; and a flat bill and webbed feet like a duck. In fact, the first time a platypus was brought from Australia to Britain, people couldn't believe that it was a real animal.

Platypus Facts Most mammals give birth to live young, while most other animals lay eggs, such as reptiles and fish (some of which are also live-bearers), amphibians and … birds. There are three species of egg-laying mammals, known as monotremes.

- Platypuses are mammals, but not marsupials (pouched mammals). They are monotremes, that is, egg-laying mammals. After a short gestation period, the mother lays an egg containing the baby.About ten days later, the egg hatches, and the baby emerges.Marsupials also have short gestation periods, but after it is done, there is live birth.lthough a mammal with a pouch is always a marsupial (with the exception of the echidna, which develops a rudimentary pouch during breeding season), not all marsupials have pouches, for example, the numbat of Western Australia. All marsupials are mammals, but not all mammals are marsupials.

Monotremata monotremes Monotremes are endothermic, but they have unusually low metabolic rates and maintain a body temperature that is lower than that of most other mammals. The eggs layed by monotremes are small (13-15 mm diameter) and covered by a leathery shell. The number of eggs laid is small, usually 1-3, and they are placed in the mother's pouch. They contain a large yolk, which is concentrated at one end of the egg very much like the yolk of a bird's egg.

There are only 2 mammals on earth that lay eggs; one is the platypus and the other is? The echidna. Echidnas, also known as spiny anteaters, belong to the family Tachyglossidae in the monotreme order of egg-laying mammals. There are four extant species, which, together with the platypus, are the only surviving members of that order and are the only extant mammals that lay eggs. http://en.wikipedia.org/wiki/Echidna.

Platypus The platypus, specifically the Duck-Billed Platypus, is indigenous to eastern Australia and Tasmania, with the platypus being one of the only mammals that lays eggs (the only other mammal that does lay eggs is the echidna) as mammals generally give birth to live young.he platypus is a semi-aquatic animal and can be found inhabiting streams and rivers in the colder highlands of Australia and Tasmania, as well as tropical rainforests.

What Are the Three Groups of Mammals? The three major groups of mammals are monotremes, which lay external eggs; marsupials, which carry their babies in a pouch; and placental mammals, which carry and gestate their fetuses internally. Humans fall into the category of placental mammals. Examples of monotremes and marsupials are the platypus and the kangaroo, respectively. Keep Learning.

Platypus Platypuses are both bizarre looking and unusually adapted. They belong to a sub-group of mammals that lay eggs rather than giving birth to live young (monotremes). When the first platypus was shipped to Britain from Australia, people thought it was a joke and that someone had sewn a duck's bill to a mammal's body.hey belong to a sub-group of mammals that lay eggs rather than giving birth to live young (monotremes).

- This is true and false.Most mammals do not lay eggs, but instead give live birth. There are, however, just two egg-laying mammals, which are members of the order Monotremata, so they are known as monotremes. Platypuses and echidnas are egg-laying mammals.

Eutheria Eutherians, often called placental mammals, have a unique reproductive system in which unborn young are nourished for an extended period via a placenta. This system permits retention of the young in the protective environment of the uterus during most of early development.

What are the only mammals that lay eggs? 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 yo … ung on mothers' milk-a characteristic unique to mammals alone. There are just three known species of egg-laying mammals, or monotremes.

Echidna Facts Echidna Facts. Echidna is a type of primitive mammals that belongs to the group of monotremes (mammals that lay eggs). Genus Echidna consists of two species: short-beaked echidna and long-beaked echidna. Short-beaked echidna inhabits Australia and New Guinea, while long-beaked lives only in the highlands of New Guinea.

Which Types of Animals Are Monotremes? By Laura Klappenbach. 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.Monotremes differ from other mammals in that they have a singoe opening for their urinary, digestive and reproductive tracts (this single opening is known as a cloaca and is similar to the anatomy of reptiles).onotremes lay eggs and like other mammals lactate (produce milk) but instead of having nipples like other mammals, monotremes secrete milk through mammary gland openings in the skin. Adult monotremes do not have any teeth. Monotremes are long-lived mammals.

- What kind of mammals carry immature offspring in pouches? These are the marsupials, which include animals such as kangaroos, koalas, wombats, possums, wallabies and Tasmanian devils, to name a few. Not all marsupials have fully deve … loped pouches, but all marsupials give birth to very undeveloped young.

Bad Math Props Up Trumpâs Border Wall If you wanted a wall instead of a fence—and if it truly were, as Trump has promised, 35 to 65 feet of concrete reinforced with steel—then the costs would mount extremely fast. Imagine a 1,000-mile wall, at a height of about 50 feet, the middle of the range that Trump has thrown out.

- Echidnas are monotremes, or egg-laying mammals. Covered with fur out of which dozens of sharp spines protrude, the echidna is sometimes known as the spiny anteater. Although … the echidna is not at all related to anteaters, it does feed primarily on termites and ants.he echidna lays eggs, making it a monotreme, but it is also a mammal, as the young suckle mother's milk. During breeding season, the female echidna develops a pouch, where she lays and incubates her egg. The pouch is little more than a fold of skin, and even the male can develop a pouch.

Egg-laying Mammals 1 Short-beaked echidnas are popular with zoos, since they are the only representative of egg-laying mammals established in captivity. 2  These echidnas can live for more than 50 years in captivity. 3  Echidnas have very poor eyesight, but they more than make up for this with excellent hearing.
