Topic: List of monotremes and marsupials


  
  List of monotremes and marsupials - Wikipedia, the free encyclopedia
The class Mammalia (the mammals) is divided into two subclasses based on reproductive techniques: egg laying mammals (the monotremes); and mammals which give live birth.
The latter subclass is divided into two infraclasses: pouched mammals (the marsupials); and the placental mammals.
This list contains the Monotremes and the Marsupials.

 Platypus - Wikipedia, the free encyclopedia
The platypus, like the other monotremes, are the only mammals known to have a sense of electroception: it locates its prey in part by detecting their body electricity.
The platypus and other monotremes were very poorly understood for many years, and to this day some of the 19th century myths that grew up around them endure, for example, that the monotremes are "inferior" or quasi-reptilian, and that they are the distant ancestor of the "superior" placental mammals.
It is now known that modern monotremes are the survivors of an early branching of the mammal tree; a later branching is thought to have led to the marsupial and placental groups.

 Koala - Encyclopedia, History, Geography and Biography
The Koala (Phascolarctos cinereus) is a thickset arboreal marsupial herbivore native to Australia, and the only extant representative of the family Phascolarctidae.
Its origins are unclear; however, since its pouch opens backwards instead of forwards like most other marsupials, it is theorised that it may have evolved from a burrowing marsupial.
The Koala is broadly similar in appearance to the wombat (its closest living relative), but has a thicker, softer coat, much larger ears, and longer limbs, which are equipped with large, sharp claws to assist with climbing.

 Carnegie team finds earliest known relative of marsupials   (Site not responding. Last check: 2007-11-01)
Marsupial mammals are born at an early stage and carried in a pouch on their mother's abdomen until fully developed.
Marsupial evolution, Cifelli explained, "has always been a North American story." The oldest previous marsupial find was a 100-million-year-old fossil collected in Utah and described by Cifelli.
Until now, many scientists had suspected that marsupial mammals -- whose females carry their immature offspring in pouches -- had developed in North America and placental mammals -- whose offspring have a longer gestation period and are born more fully developed -- in Asia.

 Marsupials - EPA/QPWS
Many carnivorous marsupials have folds of skin that swell to act as a temporary pouch during the breeding season.
Newborn marsupials are furless and have underdeveloped hind limbs and tail.
Marsupials are born in a very immature state, weighing between 0.1g and 1g and are about the size of a jellybean.

 f01 Living mammals are placentals (eutheria), marsupials, and monotremes
Monotremes, by virtue of their hair and in having but one bone in their lower jaw, are mammals.
During the Cenozoic, marsupials in the southern continents evolved in isolation from carnivorous placentals.
The ancestral marsupials of the southern continents were thus escapees from competition and the physical isolation of the southern continents had allowed them their run of evolutionary experimentation.

The Koala is found all along the eastern coast of Australia from near Adelaide to the southern part of Cape York Peninsula, and as far into the hinterland as there is enough rainfall to support suitable forests.
It is commonly said that the common name 'Koala' is an Aboriginal word meaning "no drink." {{dubiousNo Water}} The Koala actually does drink water, but only rarely, due to its diet consisting of eucalyptus leaves, which contain sufficient water to obviate the need for the Koala to climb down for a drink.
At birth the joey, only the size of a jelly bean, crawls into the downward-facing pouch on the mother's belly (which is closed by a drawstring-like muscle that the mother can tighten at will) and attaches itself to one of the two teats.

Marsupials are a unique group of mammals, typically associated with Australasia, although many species occur in South America.
The last 20 years have seen many exciting discoveries leading to significant developments in the understanding of marsupial biology, so much so that they are coming to be seen as model organisms in studies of life history evolution, ageing and senescence, sex determination and the development and regeneration of the nervous system.
The impact of these developments have been such that marsupials are coming to be seen as model organisms in studies of life history evolution, ageing and senescence, sex determination and the development and regeneration of the nervous system.

 Re: Alien Autopsy Film Review - Gehrman   (Site not responding. Last check: 2007-11-01)
While the laying of eggs by the monotremes is the best-known and most obvious similarity that they have to the reptiles, there are a number of other similarities, which will be examined in the next section.
It is inaccurate, however, to consider the monotremes and marsupials as "living fossils" -- they have had an independent evolutionary history of some 180Myr, and perform better than placental mammals at some "typically mammalian" tasks, like thermoregulation [3:ch 4,9].
One feature of monotremes which I don't know where it fits is the mechanism for sex determination: "The male is heterogametic, that is, he produces two kinds of sperm, as humans do, one with a Y chromosome and the other with an X chromosome...

 Marsupials belong to the Class Mammalia
Marsupials have the same highly derived skeletons, jaws and teeth as placentals.
Marsupials differ in giving birth to tiny undeveloped young after a short pregnancy, but then lactating for a longer period than placentals.
In Australia marsupials were dominant and are still the most diverse but the bats and rodents, which were late arrivals are now the most numerous.

 Action Plan for Australian Marsupials and Monotremes - Summary
This Action Plan, which was prepared by the IUCN Species Survival Commission's Australasian Marsupial and Monotreme Specialist Group (AMMSG) for the Australian Nature Conservation Agency, reviews the conservation status of 209 taxa of Australian monotremes and marsupials: one species and three subspecies of monotremes and 112 species and 93 subspecies of marsupials.
This Action Plan lists 16 taxa as Extinct (EX), one as Extinct in the Wild (EW), five as Critically Endangered (CR), 17 as Endangered (EN), 31 as Vulnerable (VU), one as Lower Risk (conservation dependent) (LR(cd)), 41 as Lower Risk (near threatened) (LR(nt)), and three as Data Deficient (DD).
The main causes of extinction and decline in marsupials have been identified and include the introduction to Australia of predators such as the Red Fox and Feral Cat and of herbivores such as the Rabbit, Sheep and Cattle, habitat destruction through land clearing, and changed fire regimes.

 --X--ANIMAL LIST--X--
Mammals are, however further divided into 3 orders: placentals - like us whose young are born in an advanced state, marsupials whose young are born in an embryonic stage, their development being completed in the mothers pouch, and monotremes, or egg laying mammals.
Mammals are defined as being vertabrate animals with body hair, mammary glands, and 4 limbs, which are modified into fins in most aquatic mammals.They breath air and are warm blooded - that is there internal body temperature remains more or less constant, regardless of the surrounding, external temperature.
Mammals reproduce by true mating between amles and females and, with the exeption of monotremes, the young develop inside the females' uterus.

In June 1995, the AKF provided AMMSG with a copy of a nomination of the Koala for listing in Schedule 1, Part 1 (Species that are Endangered), of the Endangered Species Protection Act 1992.
On 25 January 1996, after receiving a draft of the Taxon Summary for the Koala, Ms Tabart wrote to the Editors expressing her concern at the assessment of LR(nt) and reiterating the AKF's view, as stated in the November 1995 letter, that the species should be listed as Vulnerable.

 Alibris: Marsupials
The ecological literature on marsupials is dominated by descriptive natural history, and there has hitherto been little attempt at either synthesis or evolutionary interpretation.
Marsupials differ from most other mammals in their method of reproduction, in that they have chosen, in an evolutionary sense, to develop lactation rather than placentation for the nurture of their young.
There is an urgent need for concerted action to conserve the marsupials and monotremes of the Australasian region.
