Marsupials

Seals are placental mammals, as the young complete their development within the mother's uterus, attached to a placenta. They do not have a pouch like most marsupials, and they do not lay eggs like monotremes.

Little research has been done on the Monito del monte, so it is not known how long it lives. Its lifespan is believed to be about two years.

Yes. The only species of marsupial in North America is the Virginia Opossum, with a range that also extends south. In central America, there is the Yapok, a type of water-possum, while in South America can be found the Monito del Monte.

Marsupials, monotremes and placental mammals are all mammals. They share the following characteristics: * vertebrates * warm-blooded * have fur, skin or hair * breathe through lungs (not gills) * the young feed on mother's milk The major differences, however, include: * monotremes are the only mammals which lay eggs * marsupial young are born undeveloped and continue most of their growth and development whilst they are in the mother's pouch, attached firmly to the teat for several months, where they receive all their nutrients.

What on earth did your glider get into????

It is not recommended that a glider gets bathed, since they are not the greatest swimmers ever.... Not to mention, the horrible sicknesses that can and WILL occur if any water is inhaled or soap ingested. They also get Hypothermia very fast.

If you glider gets super smelly, it is one of these:

Time to clean the cage and toys

Change the diet to a vet recommended diet

Glider is sick

If your glider's fur is uber smelly, get a box of huggies baby wipes and let the glider shimmy it's way through. Do that a few times a week until the glider is no longer smelly. Just remember that the glider needs to be warm after doing so. Let it hang out in your shirt to dry. :)

Unfortunately, too little, too late, was done to protect the Tasmanian tiger. In fact, a bounty was placed on the Tasmanian tiger as farmers feared than as a threat to livestock.

The Tasmanian government did not act to protect the Thylacine (as it was properly called) until 1936, the same year as its believed extinction.

Greater gliders eat a variety of eucalyptus leaves of the subgenus Monocalyptus. They also feed on nectar from the flowers of those eucalyptus species.

No. The numbat is not like an armadillo. It does not roll into any spherical shape when threatened. Its only defence is to hide in hollow logs and crevices in trees or rocks.

Sugar Gliders are not the same as Sugar Bears. Sugar Gliders are Marsupials and Bears are mammals.

The sandhill dunnart is subject to predation by introduced species such as foxes and feral cats and dogs. There is also the problem of habitat loss, and changed fire regimes since the introduction of European settlement.

In its native habitat, the sandhill dunnart is only known on the Eyre Peninsula of South Australia, in arid dune areas which are well-covered by spinifex, a low, wiry desert grass of Australia. Because of this, its habitat may be affected by bushfires.

The embryo in a placental mammal is fully developed within the mother's uterus, sustained by the placenta, through which it receives all the nutrition it needs. Its organs are fully developed and it is able to survive outside the mother's body once it is born. It requires mothers' milk (or a suitable substitute) when it is born, but it can live independently of the mother, given the right care.

Baby marsupials are born extremely undeveloped, and are unable to survive at all outside the mother's body, until they can reach the pouch. They are born after a much shorter gestation period than a placental of equivalent size, and even the largest species of marsupial is only the size of a jellybean when it is born. After birth, it must climb up the outer fur of the mother and into the pouch where it attaches itself to a nipple. The teat swells in the joey's mouth, securing it in place so it cannot be accidentally dislodged. The joey will usually stay in the pouch for about 6-9 months, depending on the species, until it is developed enough to leave the pouch and move about independently.

Monotremes are the only type of mammals which lay eggs.

Monotremes include the platypus, the short-beaked echidna (both found in Australia) and the long-beaked echidna, which is endemic to New Guinea.

No marsupials originated in North America. The opossums that live in Central America, and the Virginia Opossum, which is found as far north as southern Canada, all originated in South America but moved to North America when the two Americas joined together about three million years ago.

Apart from the obvious differences in reproductive organs, there is very little difference between male and female numbats. Despite being a marsupial, the female numbat does not even have a pouch.

The males tend, on average, to be about 20 grams more in weight than the females.

When an opossum gets threatened it will growl, urinate, burp\belch, and or play dead yes it does seem funny but its so true. look it up if you don't believe me. A opossum may if it can just lay down and play dead when it feels threatened, but if this does not work for them, they will try to defend themselves as best they can, mainly with their teeth. yep and they can play dead up to 4 hours!!!!!

The fur of sugar gliders is bluish-grey, although individuals may have more tan tones. They have a black stripe which goes from their nose, over their head, to their back, and the tip of their tail is black also. Their underbelly tends to be a pale cream colour. There can also be albino sugar gliders.

Numbats, being mammals, reproduce sexually. Breeding occurs during Australia's summer months, and the gestation period is about 14 days.

As they are marsupials, they give birth to live young which are undeveloped, hairless and about the size of a jellybean.

At birth, numbats joeys, of which there are usually 2-4, crawl by instinct to the mother's teats which then swell in their mouth. The numbat is unusual because, unlike other marsupials, it does not have a closed pouch. the joeys cling to the mother's underbelly until they are three to four months old. After this time, the joeys are left in a burrow during the day while the mother finds food. They may be transported on her back to new shelters.

Young joeys are ready to leave the mother at nine to ten months old, whereupon they move away from the mother's territory to establish their own territory. Numbats are ready to reproduce at about one year old. Their lifespan is 3-4 years in the wild, and up to 6 years in captivity.

The age of sexual maturity in sugar gliders varies slightly between the males and females. The males reach maturity between 3-12 months old while females reach maturity between 5-18 months.One distinctive characteristic on the males which forms as they reach sexual maturity is a "bald spot" on the top of their head which is in fact a sweat gland. In the wild, sugar gliders breed only once a year due to climate and habitat conditions while they can breed up to 4 times a year in captivity as a result of consistent living conditions.

A sugar glider female can have up to 4 joeys at time, while one to two is more common. The gestation period lasts only 16 days, after which the baby sugar glider will crawl into a mother's pouch for further development. It is virtually unnoticeable the female is pregnant until after the joey has climbed into her pouch and begins to grow, forming bumps in her pouch. Once in the pouch, the joey will attach itself to its mother's nipple where it will stay for about 8-9 weeks. The joey gradually spills out of the pouch until it falls out completely. Their eyes will remain closed for another 12-14 days and they are virtually furless at first. During this time they will begin to mature by starting to grow fur and increasing gradually in size. They will continue to nurse for at least another 5 weeks, after which the weaning process begins and they will become more independent.

A misnomer posed by some earlier poster is that it is like a reptile. The correct answer is, it is not considered the most primitive mammal. This was incorrectly presumed by 19th century scientists. It is actually uniquely evolved.

If you're attempting to find out the most primitive "modern" mammals, they could be argued to be the Soricidae, the shrews and the Talpidae, the moles, but any modern creature is simply not primitive. More basic, more complex, more or less evolutionary divergent from their ancestral norms, but not more primitive.

they have feer that is thick and holds in the heat.

Most marsupials have sharp teeth at the very front, whether they are herbivores (like wombats and koalas) or carnivores (like Tasmanian devils and quolls). Some then have grinding molars further back.

Kangaroos' teeth are different again. Kangaroos are grazing animals and they need strong teeth for chewing the grass they eat. The teeth of the kangaroo are continuously being worn down by the tough grasses they eat. Instead of continuously growing, once a kangaroo's front teeth are worn down completely, they fall out, and the back teeth move forwards to take the place of the worn front teeth. Kangaroos have four such pairs of chewing teeth.
