Template:Honor desc

The requirements listed below reflect those reviewed by the South Pacific Division. The General Conference approved honor requirements (and the honor name itself) are substantially different.

The South Pacific Division created this version of the Marsupial Honor because 70% of marsupial species and 100% of monotremes are native to Australia and nearby islands. Before the Age of Discovery there were NO other mammals (other than mankind) in Australia.

1. Have the Mammals 1 honor.

For tips and instruction see Mammals.

2. Distinguish:

a. Mammal from other animals.

The mammals are the class of vertebrate animals characterized by the presence of mammary glands, which in females produce milk for the nourishment of young.

b. Placentals, marsupials and monotremes from one another.

Placentals
The placentals are distinguished from other mammals in that the fetus is nourished during pregnancy via a placenta.
Marsupials
Marsupials are mammals in which the female typically has a pouch (called the marsupium) in which it rears its young through early infancy. They differ from placental mammals in their reproductive traits.
Monotremes
Monotremes are mammals that lay eggs instead of giving birth to live young like marsupials and placental mammals.

3. Be able to explain the difference between, monotreme reproduction, marsupial reproduction and that in true mammals (ie. placentals).

The key anatomical difference between monotremes and other mammals is the one that gave them their name; monotreme means 'single opening' in Greek and comes from the fact that their urinary, defecatory, and reproductive systems all open into a single duct, the cloaca. This structure is very similar to the one found in birds and reptiles. Monotremes and marsupials have a single cloaca (though marsupials also have a separate genital tract), while most placental mammal females have separate openings for reproduction, urination, and defecation: the vagina, the urethra, and the anus.

Monotreme Reproduction

Monotremes lay eggs. However, the egg is retained for some time within the mother, which actively provides the egg with nutrients. Monotremes also lactate, but have no defined nipples, excreting the milk from their mammary glands via openings in their skin.

Marsupial Reproduction

The pregnant female marsupial develops a kind of yolk sack in her womb which delivers nutrients to the embryo. The embryo is born at a very early stage of development (at about 4-5 weeks), upon which it crawls up its mother's belly and attaches itself to a nipple (which is located inside the pouch). It remains attached to the nipple for a number of weeks. The offspring later passes through a stage where it temporarily leaves the pouch, returning for warmth and nourishment.

Placental Mammal Reproduction

The placenta is a temporary organ composed of two parts, one of which is part of the fetus, the other part of the mother. It is implanted in the wall of the uterus, where it receives nutrients and oxygen from the mother's blood and passes out waste. This interface forms a barrier, the placental barrier, which filters out some substances which could harm the fetus.

4. Explain the role of the pouch in marsupials and the significance of the direction of the opening of the pouch.

Kangaroo joey inside the pouch

The pouch is a distinguishing feature of female marsupials; the name marsupial is derived from the Latin marsupium, meaning pouch. Marsupials give birth to a live but relatively undeveloped fetus called a joey. When the joey is born it crawls from inside the mother to the pouch. The pouch is basically a fold of skin with a single opening that covers the nipples to protect the joey as it continues to develop.

Pouches are different amongst the different marsupials: for example for Quolls and Tasmanian Devils, the pouch opens to the rear and the joey only has to travel a short distance to get to the opening of the pouch. While in the pouch they are permanently attached to the nipple and once the young have developed they leave the pouch and do not return. The kangaroo's pouch opens horizontally on the front of the body, and the joey must climb a relatively long way to reach it. Kangaroos and wallabies allow their young to live in the pouch well after they are physically capable of leaving.

Tasmanian Devils give birth to up to 50 young, each weighing approximately 0.18–0.24 grams. When the young are born, they move from the vagina to the pouch. Once inside the pouch, they each remain attached to a nipple for the next 100 days. Despite the large litter at birth, the female has only four nipples, so that no more than four young can survive birth. On average, more females survive than males. The female Tasmanian Devil's pouch, like that of the wombat, opens to the rear, so it is physically difficult for the female to interact with young inside the pouch. Unlike kangaroo joeys, young devils (and other marsupials with rear-opening pouches) do not return to the pouch; instead, they remain in the den for another three months, first venturing outside the den between October and December before becoming independent in January.

5. Understand how marsupials and monotremes are placed into groups.

Marsupials

Marsupials are classed mainly by their dietary habits.

Herbivorous marsupials
(such as kangaroos, wallabies, koalas, wombats, and possums) eat only plants.
Carnivorous marsupials
(such as Tasmanian devils, numbats, and quolls) eat meat as at least 75% of their diet.
Omnivorous Marsupials
(such as opossums) eat just about anything they can find.

Close to 70% of the 334 extant species occur in Australia, New Guinea, and nearby islands, with the remaining 100 found in the Americas, primarily in South America, but with 13 in Central America, and one in North America north of Mexico.

Monotremes

The extant (living, not fossil only) monotreme species are grouped into two families:

Family Ornithorhynchidaethe
The Platypus being the only living example and
Family Tachyglossidae
four extant species of echidnas (or spiny anteaters)

The 5 surviving examples of monotremes are all indigenous to Australia and New Guinea.

6. Research and write a paragraph of approximately 100 words on the following. Try to include habitat, food and breeding habits. Choose different examples from those given in these trainer’s notes

The authors of this book interpret this requirement to mean writing 6 paragraphs.

a. Monotremes (choose one)

You have two choices: Platypus or Spiny Anteaters

b. Carnivorous Marsupials (choose one), and four from the following groups;

Here are three carnivorous marsupials. The following groups are labeled c. to h.

Quoll

SpottedQuoll 2005 SeanMcClean.jpg

Quolls or native cats (genus Dasyurus) are carnivorous marsupials, native to Australia and Papua New Guinea. Adults are between 25 and 75 cm long, with hairy tails about 20-35 cm long. Females have six to eight nipples and develop a pouch—which opens towards the tail—only during the breeding season, when they are rearing young. The babies are the size of a grain of rice. Quolls live both in forests and in open valley land. Though primarily ground-dwelling, they have developed secondary arboreal characteristics. They do not have prehensile tails, but do have ridges on the pads of their feet. Their molars and canines are strongly developed.

The Eastern Quoll is a solitary predator, hunting at night for its prey of insects and small mammals. They have also been known to scavenge food from the much larger Tasmanian Devil.

The breeding season begins in early winter, and the female gives birth to up to 30 young. Of these, the first to attach themselves to the six teats will be the only survivors. Weaning takes place at about 10 weeks of age, with the young staying in the den while the mother forages.

Numbat

Numbat.jpg

The Numbat is a small, colorful creature between 20 and a little under 30 cm long, with a finely pointed muzzle and a prominent, bushy tail about the same length as its body. Color varies considerably, from soft grey to reddish-brown, often with an area of brick red on the upper back, and always with a conspicuous black stripe running from the tip of the muzzle through the eyes to the bases of the small, round-tipped ears. The underside is cream or light grey; weight varies between 280 and 550 grams.

Adult Numbats are solitary and territorial; an individual of either sex establishes a territory of up to 150 hectares (370 acres)[4] early in life, and defends it from others of the same sex. The animal generally remains within it from that time on; male and female territories overlap, and in the breeding season males will venture outside their normal home range to find mates.

Another common name for the Numbat was Banded Anteater, though this has now fallen into disuse. Though it will in fact consume ants, its diet otherwise consists almost exclusively of termites.

While the numbat has relatively powerful claws for its size,[4] it is not strong enough to get at termites inside the concrete-like mound, and so must wait until the termites are active. It uses a well-developed sense of smell to locate the shallow and unfortified underground galleries that termites construct between the nest and their feeding sites; these are usually only a short distance below the surface of the soil, and vulnerable to the Numbat's digging claws.

Tasmanian Devil

Tasdevil large.jpg

The Tasmanian Devil (Sarcophilus harrisii), also referred to simply as "the devil", is a carnivorous marsupial now found in the wild only in the Australian island state of Tasmania. The Tasmanian Devil is the only extant member of the genus Sarcophilus. The size of a small dog, but stocky and muscular, the Tasmanian Devil is now the largest carnivorous marsupial in the world after the extinction of the Thylacine in 1936. It is characterised by its black fur, offensive odor when stressed, extremely loud and disturbing screech, and viciousness when feeding. It is known to both hunt prey and scavenge carrion and although it is usually solitary, it sometimes eats with other devils.

The Tasmanian Devil became extirpated on the Australian mainland about 400 years before European settlement in 1788. Because they were seen as a threat to livestock in Tasmania, devils were hunted until 1941, when they became officially protected. Since the late 1990s devil facial tumour disease has reduced the devil population significantly and now threatens the survival of the species, which in May of 2008 was finally declared to be endangered. Programs are currently being undertaken by the Tasmanian government to reduce the impact of the disease.

Tasmanian Devils can take prey up to the size of a small wallaby, but in practice they are opportunistic, and eat carrion more often than they hunt live prey. Although the devil favours wombats, it will eat all small native mammals, domestic mammals (including sheep), birds, fish, insects, frogs and reptiles. Their diet is largely varied and depends on the food available. On average, they eat about 15% of their body weight each day; however, they can eat up to 40% of their body weight in 30 minutes if the opportunity arises. Tasmanian Devils eliminate all traces of a carcass, devouring the bones and fur in addition to the meat and internal organs. In this respect, the devil has earned the gratitude of Tasmanian farmers, as the speed at which they clean a carcass helps prevent the spread of insects that might otherwise harm livestock.

c. Bandicoots and Bilbies

Bandicoots

Bandicoots are a group of about 20 species of small to medium-sized, terrestrial marsupial omnivores in the order Peramelemorphia. They are endemic to the Australia-New Guinea region.

Perameles gunni.jpg

The Eastern barred bandicoot species is nocturnal. It emerges from its nest at dusk to forage for a variety of invertebrates including crickets, beetles and earthworms. During the day it rests in a grass-lined nest. When foraging, it uses its long nose to probe deep into the soil and then digs eagerly when it locates food. Females have 8 nipples and can produce a maximum of 5 young in one litter with an average of 2 to 3 young. Gestation lasts just 12 days—this is one of the shortest gestation periods of any mammal. Young are weaned at 55 days and emerged juveniles remain dependent upon the mother and forage with her until day 86. Given ideal conditions, females can have up to five litters per year although reproduction becomes depressed in summer and ceases altogether in times of drought.

Bilbies

Bilby at Sydney Wildlife World.jpg

Bilbies, or rabbit-bandicoots, are desert-dwelling marsupial omnivores; they are members of the order Peramelemorphia. Before European colonisation of Australia, there were two species of bilby. The lesser bilby became extinct in the 1950s; the greater bilby survives but remains endangered. It makes its home in a burrow that spirals down, making it hard for its predators to get in. The bilby prefers arid habitats because of the spinifex grass and the acacia shrubs

Greater bilbies have the characteristics of long bandicoot muzzle and very long ears. They are about 29–55 centimetres (11–22 in) in length. Compared to bandicoots, they have a longer tail, bigger ears, and softer, silky fur. The size of their ears allows them to have better hearing as well. At 1 to 2.4 kilograms (2.2 to 5.3 lb), the male is about the same size as a rabbit; although male animals in good condition have been known to grow up to 3.7 kilograms (8.2 lb) in captivity. The female is smaller, and weighs around 0.8 to 1.1 kilograms (1.8 to 2.4 lb). Bilbies have an excellent sense of smell and sharp hearing. Their fur is blue-grey with patches of tan and is very soft. The tail is black and white with a distinct crest. Bilbies have strong forelimbs and thick claws, which they use to dig for food and make burrows.

Unlike bandicoots, they are excellent burrowers and build extensive tunnel systems with their strong forelimbs and well-developed claws. A bilby typically makes a number of burrows within its home range, up to about a dozen; and moves between them, using them for shelter both from predators and the heat of the day. The female bilby's pouch faces backwards, which prevents her pouch from getting filled with dirt while she is digging.

Greater bilbies are nocturnal omnivores that do not need to drink water, as they get all the moisture they need from their food, which includes insects and their larvae, seeds, spiders, bulbs, fruit, fungi, and very small animals. Most food is found by digging or scratching in the soil, and using their very long tongues.[

d. Koala and Wombats

Koalas

Koala climbing tree.jpg

The Koala is broadly similar in appearance to the wombat, but has a thicker, more luxurious coat, much larger ears, and longer limbs, which are equipped with large, sharp claws to assist with climbing. Weight varies from about 14 kg for a large, southern male, to about 5 kg for a small northern female. Contrary to popular belief, their fur is thick, not soft and cuddly. Koalas' five fingers per paw are arranged with the first two as opposable thumbs, providing better gripping ability.

Wombats

Wombat at Lone Pine.jpg

Wombats are Australian marsupials; they are short-legged, muscular quadrupeds, approximately one meter (3 feet) in length and with a very short tail. Wombats have an extraordinarily slow metabolism, taking around 14 days to complete digestion, and generally move slowly. When required, however, they can reach up to 40 km/h and maintain that speed for up to 90 seconds.

When attacked, they can summon immense reserves of strength — one defense of a wombat against a predator (such as a Dingo) underground is to crush it against the roof of the tunnel until it stops breathing.

e. Possums

Brushtail possum.jpg

Possums are small marsupials with brown or grey fur, ranging in size from the length of a finger (pygmy possums and wrist-winged gliders), to the length of a forearm (brushtails and ringtails). All possums are nocturnal and omnivorous, hiding in a nest in a hollow tree during the day and coming out during the night to forage for food. They fill much the same role in the Australian ecosystem that squirrels fill in the northern hemisphere and are broadly similar in appearance.

The two most common species of possums, the Common Brushtail and Common Ringtail, are also among the largest.

f. Kangaroos and their relatives

These animals are called macropads.

Kangaroos

There are three species of kangaroo:

  • The Red Kangaroo (Macropus rufus) is the largest surviving marsupial anywhere in the world. Fewer in numbers, the Red Kangaroos occupy the arid and semi-arid centre of the continent. A large male can be 2 metres (6 ft 7 in) tall and weigh 90 kg (200 lb).
  • The Eastern Grey Kangaroo (Macropus giganteus) is less well-known than the red (outside of Australia), but the most often seen, as its range covers the fertile eastern part of the continent.
  • The Western Grey Kangaroo (Macropus fuliginosus) is slightly smaller again at about 54 kg (119 lb) for a large male. It is found in the southern part of Western Australia, South Australia near the coast, and the Darling River basin.

Wallabies

Red-necked-Wallaby.jpg

Essentially, a wallaby is any macropod that isn't large enough to be considered a kangaroo and has not been given some other name. There is no fixed dividing line. In general, a wallaby is smaller and has a stockier build than a kangaroo; a wallaroo is any of a few species somewhat intermediate in size between a wallaby and a kangaroo.

Quokka

Rottnest Quokka 2004 SeanMcClean.jpg

The Quokka (Setonix brachyurus), the only member of the genus Setonix, is a small macropod about the size of a large domestic cat. Like other marsupials in the macropod family (such as the kangaroos and wallabies), the Quokka is herbivorous and mainly nocturnal.

In the wild, its roaming is restricted to a very small range in the South-West of Western Australia. The Quokka has become rare, but remains a protected species on islands off the coast of that area, Bald Island, Rottnest Island, Garden Island and rarely Penguin Island. The islands are free of foxes and cats. On Rottnest Island, it is common and occupies a wide range of habitats, ranging from semi-arid scrub to cultivated gardens.

The Quokka is gregarious and gathers in large groups where food is available: primary items are grasses, sedges, succulents and foliage. The health of some animals has suffered significantly by the ingestion of inappropriate foods, such as bread, given by well meaning visitors to Rottnest Island. Visitors are now asked to refrain from feeding them. It breeds at any time on the mainland, but in late summer on Rottnest. The Quokka only produces a single joey in a year. Restricted availability of the trace element copper appears to be a major limiting factor of the ability of the Quokka to breed on Rottnest.

The Quokka's movements are similar to a kangaroo, using mixture of small and large hops.

Tree-kangaroo

Buergers' Tree-kangaroo back and tail.jpg

Tree-kangaroos are macropods adapted for life in trees. They are found in the rainforests of New Guinea, far northeastern Queensland, and nearby islands, usually in mountainous areas. Although most are found in mountainous areas, several species also occur in lowlands, and one, the aptly named Lowlands Tree-kangaroo, appears to be restricted to lowlands.

Tree-kangaroos feed mostly on leaves and fruit, taken both in trees and on the ground, but other foods are eaten when available, including grain, flowers, sap, bark, eggs and young birds. Their teeth are adapted for tearing leaves rather than cutting grass.

Wallaroo

Macropus robustus.jpg

A wallaroo is any of three closely related species of moderately large macropod, intermediate in size between the kangaroos and the wallabies. The name "wallaroo" is a portmanteau of wallaby and kangaroo. In general, a large, slim-bodied macropod of the open plains is called a "kangaroo"; a small to medium-sized one, particularly if it is relatively thick-set, is a "wallaby": most wallaroos are only a little smaller than a kangaroo, fairly thickset, and are found in open country. All share a particular habit of stance: wrists raised, elbows tucked close into the body, and shoulders thrown back, and all have a large, black-skinned rhinarium.

The best-known species is Macropus robustus, which is known as the Eastern Wallaroo, Common Wallaroo or just Wallaroo on the slopes of the Great Dividing Range (which runs for more than 3,000 km around the eastern and south-eastern coast of Australia), and as the Euro in most of the rest of the continent. There are four subspecies: the Eastern Wallaroo and the Euro, which are both widespread, and two of more restricted range, one from Barrow Island, the other from the Kimberley.

The Black Wallaroo (Macropus bernardus) occupies an area of steep, rocky ground in Arnhem Land. At around 60 to 70 cm in length (excluding tail) it is the smallest wallaroo and the most heavily built. Males weigh 19 to 22 kg, females about 13 kg. Because it is very wary and is found only in a small area of remote and very rugged country, it is remarkably little known.

The Antilopine Wallaroo (Macropus antilopinus) is the exception among wallaroos. It is, essentially, the far-northern equivalent of the Eastern and Western Grey Kangaroos. Like them, it is a creature of the grassy plains and woodlands, and gregarious, where the other wallaroos are solitary. Because of this difference, it is sometimes called the Antilopine Kangaroo.

Pademelon

RedNeckedPademelon-front-800.jpg

A pademelon is any of seven species of small marsupials of the genus Thylogale. They are usually found in forests. Pademelons are the smallest of the macropods. The name is a corruption of badimaliyan, from the Dharuk Aboriginal language of Port Jackson.

Pademelons, wallabies, and kangaroos are very alike in body structure, and the names just refer to the three different size groups. Originally wallabies were divided into small and large wallabies, but a more suitable name was needed to differentiate between them.

Besides their smaller size, pademelons can be distinguished from wallabies by their shorter, thicker, and sparsely haired tails.

If there are no predators, such as dogs, they graze in the early mornings or evenings on grassy slopes near thickets into which they can quickly escape at the first sign of danger. Having noticed danger, such as a python, they may try to warn others by stomping their feet on the ground producing surprisingly loud sound. Pademelons are nocturnal and tend to feed at night.

Their main diet is made up of grasses, leaves, and small shoots. They do little damage to crops and are not as aggressive as wallabies and kangaroos can be, making them gentle pets.

Normally, a group of females would stay on the territory with males showing up, only when one of the females is ready for mating. This is in contrast to the behavior of bigger kangaroos, who stay in mixed mobs with a male leader.

g. Opossums

AwesomePossum-AmericanOpossum.jpg

Opossums are nocturnal marsupials found in the Western Hemisphere. They are small to medium-sized creatures, about the size of a large house cat. Although there are many exceptions, most of them spend time living both in trees and on the ground, and they eat many different things (plants and animals).

Opossums are usually nomadic, staying in one area as long as food and water are easily available. Though they will temporarily occupy abandoned burrows, they do not dig or put much effort into building their own. They favor dark, secure areas, below ground or above.

When threatened or harmed, they will "play possum", mimicking the appearance and smell of a sick or dead animal. The lips are drawn back, teeth are bared, saliva foams around the mouth, and a foul-smelling fluid is secreted from glands. This response is involuntary, rather than a conscious act. Their stiff, curled form can be prodded, turned over, and even carried away. Many injured opossums have been killed by well-meaning people who find a catatonic animal and assume the worst. If you find an injured or apparently dead opossum, the best thing to do is leave it in a quiet place with a clear exit path. In minutes or hours, the animal will regain consciousness and escape quietly on its own.

h. Shrew Possums

Shrew opossum - Caenolestidae.png

Shrew opossums (also known as rat opossums) are about the size of a small rat (9–14 cm long), with thin limbs, a long, pointed snout and a slender, hairy tail. They are largely meat-eaters, being active hunters of insects, earthworms and small vertebrates. They have small eyes and poor sight, and hunt in the early evening and at night, using their hearing and long, sensitive whiskers to locate prey. They seem to spend much of their lives in underground burrows and on surface runways.

Largely because of their rugged, inaccessible habitat, they are very poorly known and have traditionally been considered rare. Recent studies suggest that they may be more common than had been thought.


7. Be able to explain the need for the conservation of marsupials.

Many marsupials have been listed as endangered species. Until the Europeans arrived in Australia, it was an isolated continent and no placental mammals (other than man) were able to travel there. When the Europeans arrived on ships, they brought placental mammals with them - sometimes intentionally, as in the case of cattle and sheep, and sometimes unintentionally, as in the case of rats and mice. These placental mammals pose a great threat to the native marsupials, as they compete for the same resources, often displacing them.

8. Do one of the following:

a. Observe a marsupial (or group of marsupials) in its native habitat and write a report of no less than 100 words describing your observations. (For those living in Australia, this is the preferred option).

Close to 70% of the 334 extant species occur in Australia, New Guinea, and nearby islands, with the remaining 100 found in the Americas, primarily in South America, but with 13 in Central America, and one in North America north of Mexico. If you live in North America and can't travel, your only option is to find an opossum or see the following options. See the list of topics worth touching on in point b.

b. Write a report of your visit to a natural history museum, wild-life sanctuary, zoo, etc. indicating in no less than 100 words, the extent of your observations. Confine your report to marsupials.

The place you visit should presumably have some marsupials in its collection, and the 100 plus words should document observations of the marsupials. Here are some ideas for the sorts of things you might be looking for:

  • Species: what is the name of this marsupial? What is its scientific name?
  • Natural habitat: where does this animal live in the wild?
  • Artificial habitat: how were its needs being met (if it was a live animal)
  • Diet: How does its natural diet compare to its diet in the sanctuary or zoo?
  • Conservation Status: is this animal threatened or endangered? If so, what is being done to conserve it?
  • Breeding: Were the animals in this collection part of a breeding program?
  • Young: Did you see any young marsupials? Were they in their mother's pouch?
  • Unique Features: what is unique about this animal?
  • Fascinating Features: what did you like best about this animal?

Adventist Youth Honors Answer Book/Zoo Visit

c. Give a talk of at least three minutes, to a group of people about marsupials or a particular marsupial.

After learning about the animals in this honor, this should be easy. If your church has a children's story during the worship service, consider turning your talk into a story. You might even want to check out the Christian Storytelling honor!

d. Guide (or assist in guiding) a group of young people (ie Friends or Companions) on a visit to a museum, zoo or sanctuary where there are marsupials.

A good option for older Pathfinders or adults. See comments on option b.
