62-691: Animal crackers are a snack of sweet crackers in animal shapes. Animal Crackers may also refer to: Animal cracker In the late 19th century, animal-shaped crackers (or " biscuits " in World English terminology) called "Animals" were imported from England to the United States. The demand for these crackers grew to the point that bakers began to produce them domestically. Stauffer's Biscuit Company produced their first batch of animal crackers in York, Pennsylvania , in 1871. Other domestic bakeries, including

124-465: A European and a koala was in 1798, and an image of the animal was published in 1810 by naturalist George Perry . Botanist Robert Brown wrote the first detailed scientific description in 1814, although his work remained unpublished for 180 years. Artist John Gould illustrated and described the koala, introducing the species to the British public. Further details about the animal's biology were revealed in

186-418: A body length of 60–85 cm (24–33 in) and weighs 4–15 kg (8.8–33.1 lb). Fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south. These populations are possibly separate subspecies , but not all researchers accept this. Koalas typically inhabit open Eucalyptus woodland, as

248-418: A broad, dark nose with a good sense of smell, and it is known to sniff the oils of individual branchlets to assess their edibility. Its relatively small eyes are unusual among marsupials in that the pupils have vertical slits, an adaptation to living on a more vertical plane. Its round ears provide it with good hearing, and it has a well-developed middle ear . The koala larynx is located relatively low in

310-400: A circus wagon fitted out as a cage and animals within it. "Barnum" refers to the famous showman and circus entrepreneur P. T. Barnum , but Nabisco does not pay a licensing fee to Barnum and Bailey Circus . The product actually says "Barnum's Animals", subtitled "Crackers". Half of the wheels are printed on the large sides of the box but at one time the printed wheels continued to the bottom of

372-403: A eucalyptus diet: the palate shifted towards the front of the skull; the upper teeth were lined by thicker bone, molars became relatively low compared to the jaw joint and with more chewing surface; the pterygoid fossa shrank; and a larger gap separated the incisor teeth and the molars. P. cinereus may have emerged as a dwarf form of the giant koala ( P. stirtoni ), following

434-448: A female gives birth to one joey or occasionally, twins. The young are born tiny and barely formed, weighing no more than 0.5 g (0.018 oz). However, their lips, forelimbs, and shoulders are relatively advanced, and they can breathe, defecate and urinate. The joey crawls into its mother's pouch to continue its development. Female koalas do not clean their pouches, an unusual trait among marsupials. The joey latches on to one of

496-408: A koala makes a low closed-mouth grunt. Koalas also communicate with facial expressions. When snarling, wailing, or squawking, the animal curls the upper lip and points its ears forward. Screaming koalas pull their lips and ears back. Females form an oval shape with their lips when annoyed. Agonistic behaviour typically consists of quarrels between individuals who are trying to pass each other on

558-468: A large gap (a characteristic feature of herbivorous mammals). The koala bites a leaf with the incisors and clips it with the premolars at the petiole , before chewing it to pieces with the cusped molars. Koalas may store food in their cheek pouches before it is ready to be chewed. The partially worn molars of koalas in their prime are optimal for breaking leaves into small particles, resulting in more efficient stomach digestion and nutrient absorption in

620-521: A male can overpower a female. A female may scream and vigorously fight off her suitors but will accede to one that is dominant or familiar. The commotion can attract other males to the scene, obliging the incumbent to delay mating and fight off the intruders. A female may learn who is more dominant during these fights. Older males typically accumulate scratches, scars, and cuts on the exposed parts of their noses and their eyelids. Koalas are induced ovulators . The gestation period lasts 33–35 days, and

682-569: A new tree, he rubs his chest against it and sometimes dribbles urine. This scent-marking behaviour probably serves as communication, and individuals are known to sniff the bottom of a newly found tree. Chest gland secretions are complex chemical mixtures — about 40 compounds were identified in one analysis — that vary in composition and concentration across season and age. Adult males communicate with loud bellows — "a long series of deep, snoring inhalations and belching exhalations". Because of their low frequency , these bellows can travel far through

744-745: A tree. This occasionally involves biting. Strangers may wrestle, chase, and bite. In extreme situations, a larger male may try to displace a smaller rival from a tree, chasing, cornering and biting it. Once the individual is driven away, the victor bellows and marks the tree. Pregnant and lactating females are particularly aggressive and attack individuals who come too close. In general, however, koalas tend to avoid fighting due to energy costs. Koalas are seasonal breeders, and give birth from October to May. Females in oestrus lean their heads back and shake their bodies. Despite these obvious signals, males try to copulate with any female during this period, mounting them from behind. Because of his much larger size,

806-547: A variety of special runs themed for holidays are released annually, such as black cats on Halloween . The Borden corporation also produced a brand of animal crackers, until the late 1970s. They came in a red box, which featured the famous Elsie the Cow logo. Market Square Food Company Inc. in Illinois has also produced its own brand of animal crackers since 1982. Its animal crackers are distributed by several major retailers throughout

868-590: A very early stage of development. They crawl into their mothers' pouches , where they live for their first six to seven months. They are fully weaned around a year old. Koalas have few natural predators and parasites, but are threatened by pathogens such as Chlamydiaceae bacteria and koala retrovirus . Because of their distinctive appearance, koalas, along with kangaroos and emus , are recognised worldwide as symbols of Australia . They were hunted by Indigenous Australians and depicted in myths and cave art for millennia. The first recorded encounter between

930-426: A weight of 4–15 kg (8.8–33.1 lb), making it among the largest arboreal marsupials. Koalas from Victoria are twice as heavy as those from Queensland. The species is sexually dimorphic : males are 50% larger than females. Males' noses are more curved and sport chest glands, which are visible as bald patches. The female's pouch opening is secured by a sphincter which holds the young in. The pelage of

992-418: A year. Those bright circus boxes are produced in three colors—red, blue, and yellow—with different variety of animals on each. In August 2018, Mondelez International (the parent company of Nabisco) released a new design for its Barnum's Animals Crackers boxes in the United States, showing the animals freed from their traditional circus boxcar cages. This design change was made in consultation with People for

1054-426: Is classified with wombats (family Vombatidae ) and several extinct families (including marsupial tapirs , marsupial lions and giant wombats ) in the suborder Vombatiformes within the order Diprotodontia . The Vombatiformes are a sister group to a clade that includes macropods ( kangaroos and wallabies ) and possums . The koala's lineage possibly branched off around 40 million years ago during

1116-482: Is derived from the Greek words φάσκωλος ( phaskolos ) ' pouch ' and ἄρκτος ( arktos ) ' bear ' . The specific name , cinereus , is Latin for ' ash coloured ' . The koala was given its generic name Phascolarctos in 1816 by French zoologist Henri Marie Ducrotay de Blainville , who did not give it a specific name until further review. In 1819, German zoologist Georg August Goldfuss gave it

1178-509: Is labeled under the name of the Kellogg Company , which acquired Keebler in 2001. Mother’s Bakery, founded in New Jersey in 1914, has sold varieties of animal crackers that they market as “Circus Animal Cookies ”, and come in pink and white frosting with the shapes of camels, hippos and lions, among others. Mother's Original Circus Animal Cookies are sprinkled with rainbow nonpareils and

1240-441: Is one-and-a-half to two years old. Females become sexually mature at about three years of age; in comparison, males reach sexual maturity at about age four, although they can experience spermatogenesis as early as two years. Males do not start marking their scent until they reach sexual maturity, though their chest glands become functional much earlier. Koalas can breed every year if environmental conditions are good, though

1302-427: Is possible that the fluid protects the brain should the animal fall from a tree. The koala's small brain may be an adaptation to the energy restrictions imposed by its diet, which is insufficient to sustain a larger brain. Its small brain limits its ability to perform complex behaviours. For example, it will not eat plucked eucalyptus leaves on a flat surface, which does not match its feeding routine. The koala has

1364-609: Is that koala was an aboriginal name from the Hawkesbury River district near Sydney. Adopted by white settlers, the word "koala" became one of hundreds of Aboriginal loan words in Australian English , where it was also commonly referred to as "native bear", later "koala bear", for its resemblance to a bear. It is one of several Aboriginal words that made it into International English alongside words like " didgeridoo " and " kangaroo ". The generic name, Phascolarctos ,

1426-615: Is the largest, with shaggier, brown fur and a wider skull. The geographic limits of these variations are based on state borders , and their status as subspecies is disputed. A 1999 genetic study suggests koalas exist as a cline within a single evolutionarily significant unit with limited gene flow between local populations. In 2016, a comprehensive phylogenetic study did not support the recognition of any subspecies. Other studies have found that koala populations are highly inbred with low genetic variation . Such low genetic diversity may have been caused by population declines during

1488-563: The Dharug gula , meaning ' no water ' . Although the vowel "u" was originally written in the English orthography as "oo" (in spellings such as coola or koolah — two syllables), the spelling later became "oa" and the word is now pronounced in three syllables, possibly in error. Related words include "kula" from Georges River to Sydney's south and west, and "kulla" (or kūlla) among southeastern Queensland ’s Dippil people . Another hypothesis

1550-556: The Eocene . The modern koala is the only extant member of Phascolarctidae , a family that includes several extinct genera and species. During the Oligocene and Miocene , koalas lived in rainforests and had broader diets. Some species, such as Nimiokoala greystanesi and some species of Perikoala , were around the same size as the modern koala, while others, such as species of Litokoala , were one-half to two-thirds its size. Like

1612-653: The binomial Lipurus cinereus . Because Phascolarctos was published first, according to the International Code of Zoological Nomenclature , it has priority as the official genus name. French naturalist Anselme Gaëtan Desmarest coined the name Phascolarctos fuscus in 1820, suggesting that the brown-coloured versions were a different species than the grey ones. Other names suggested by European authors included Marodactylus cinereus by Goldfuss in 1820, P. flindersii by René Primevère Lesson in 1827, and P. koala by John Edward Gray in 1827. The koala

1674-874: The koala to the menagerie in September 2002. Stauffer's animal crackers include bear, bison, camel, cow , cat , donkey , elephant, hippopotamus, horse , lion, mountain goat , rhinoceros, and tiger. They are made in plain (vanilla), chocolate graham, cinnamon graham, " cotton candy " and icing -covered variants, as well as "breakfast cookies" made with oats, almonds, cranberries, and pomegranate. Austin Zoo Animal Crackers currently feature bear, camel, elephant, lion, monkey, owl , penguin , rabbit , ram , rhino, turtle , and zebra. Cadburys Animals are chocolate coated and feature crocodile , elephant, hippo, monkey, lion, tiger, and toucan . Nabisco makes Barnum's Animals Crackers, with their distinctive package art of

1736-493: The koala bear , is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae . Its closest living relatives are the wombats . The koala is found in coastal areas of the island's eastern and southern regions, inhabiting Queensland , New South Wales , Victoria , and South Australia . It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, dark nose. The koala has

1798-412: The shinbone , increasing its climbing power. For a mammal, the koala has a disproportionately small brain , 60% smaller than that of a typical diprotodont , weighing only 19.2 g (0.68 oz) on average. The brain's surface is fairly smooth and " primitive ". It does not entirely fill the cranial cavity , unlike most mammals, and is lightened by large amounts of cerebrospinal fluid . It

1860-614: The 19th century by English scientists. Koalas are listed as a vulnerable species by the International Union for Conservation of Nature . Among the many threats to their existence are habitat destruction caused by agriculture, urbanisation, droughts, and associated bushfires , some related to climate change. In February 2022, the koala was officially listed as endangered in the Australian Capital Territory , New South Wales, and Queensland. The word "koala" comes from

1922-737: The Dozier-Weyl Cracker Company of St. Louis , and the Holmes and Coutts Company of New York City , were the predecessors of the National Biscuit Company , today's "Nabisco Brands". Animal biscuit crackers were made and distributed under the National Biscuit Company banner. In 1902, animal crackers officially became known as "Barnum's Animals" and evoked the familiar circus theme of the Barnum and Bailey Circus . Later in 1902,

1984-754: The Ethical Treatment of Animals (PETA), one year after the Ringling Brothers and Barnum and Bailey Circus ceased operations. The new design shows a zebra, lion, elephant, giraffe and gorilla together in an African landscape. In total, 53 different animals have been featured in Barnum's Animals Crackers since 1902. The current cookies are bear , bison , camel , cougar , elephant , giraffe , gorilla , hippopotamus , hyena , kangaroo , koala , lion , monkey , rhinoceros , seal , sheep , tiger , and zebra . To celebrate its 100th anniversary, Barnum's added

2046-592: The Queensland koala ( Phascolarctos cinereus adustus , Thomas 1923), the New South Wales koala ( Phascolarctos cinereus cinereus , Goldfuss 1817), and the Victorian koala ( Phascolarctos cinereus victor , Troughton 1935). These forms are distinguished by pelage colour and thickness, body size, and skull shape. The Queensland koala is the smallest, with silver or grey short hairs and a shorter skull. The Victorian koala

2108-415: The United States and exported to 17 countries worldwide. The cookies are baked in a 300-foot (91 m)-long traveling band oven. They are in the oven for about four minutes and are baked at the rate of 12,000 per minute. About 15,000 cartons and 330,000 cookies are produced in a single shift, using some 30 miles (48 km) of string on the packages. This runs to nearly 8,000 miles (13,000 km) of string

2170-604: The United States and internationally. Sam's Club distributes animal crackers under its "Member's Mark" house brand. In the UK , Cadburys produce a range simply called "Animals". As noted above, these biscuits have a chocolate coating on one side. In Germany , Bahlsen produces animal crackers under the Leibniz brand. In New Zealand , Arnott's manufactures Iced Animals , colourfully iced animal crackers. Koala The koala ( Phascolarctos cinereus ), sometimes called

Responding to requests from PETA, in August 2018 Nabisco released new package art displaying the animals roaming free. Stauffer Biscuit Company of York, Pennsylvania , a Japanese company owned by Meiji , also has a line of animal crackers, which are now distributed by several major discount retailers. Their use of

Having permanently left the pouch, it rides on its mother's back for transportation, learning to climb by grasping branches. Gradually, it becomes more independent. The mother becomes pregnant again after a year, when the offspring reaches around 2.5 kg (5.5 lb). She permanently severs her bond with her previous offspring and no longer allows it to suckle, but it remains nearby until it

2356-494: The cookies' visual details. Until then, animal shapes were stamped out of a dough sheet by a cutter. This produced outlines with little sophistication. By installing rotary dies , bakers can actually engrave details onto each cookie, creating a more intricate design. The rotary dies are still used today. Barnum's Animals Crackers are produced in a bakery at Fair Lawn, New Jersey , by Nabisco Brands. More than 40 million packages of Barnum's Animals Crackers are sold each year, both in

2418-1056: The disappearance of several giant animals in the late Pleistocene . A 2008 study questioned this hypothesis, noting that P. cinereus and P. stirtoni were sympatric during the mid-late Pleistocene, and that their teeth morphology displayed the major differences. The fossil record of the modern koala extends back at least to the middle Pleistocene. Vombatidae (wombats) Phascolarctidae (koalas) Acrobatidae Tarsipedidae (honey possum) Petauridae ( wrist-winged gliders and allies) Pseudocheiridae (ringtail possums and allies) Macropodidae (kangaroos, wallabies and allies) Phalangeridae ( brushtail possums and cuscuses ) Burramyidae (pygmy possums) Thylacoleonidae (extinct marsupial lion and allies) Vombatomorphia (wombats and fossil relatives) Priscakoala lucyturnbullae Madakoala spp. Perikoala robustus Nimiokoala greystanesi Litokoala dicksmithi Litokoala kutjamarpensis Phascolarctos cinereus Three subspecies have been described:

2480-517: The female's two teats and suckles it. The female lactates for as long as a year to make up for her low energy production. Unlike in other marsupials, koala milk becomes less fatty as the joey grows. After seven weeks, the joey has a proportionally large head, clear edges around its face, more colouration, and a visible pouch (if female) or scrotum (male). At 13 weeks, the joey weighs around 50 g (1.8 oz) and its head doubles in size. The eyes begin to open and hair begins to appear. At 26 weeks,

2542-399: The foliage of over 600 species of Eucalyptus is available, the koala shows a strong preference for around 30. They prefer plant matter with higher protein than fibre and lignin . The most favoured species are Eucalyptus microcorys , E. tereticornis , and E. camaldulensis , which, on average, make up more than 20% of their diet. Despite its reputation as a picky eater,

2604-616: The forest. Koalas may bellow at any time, particularly during the breeding season , when it serves to attract females and possibly intimidate other males. They also bellow to advertise their presence when they change trees. These sounds signal and exaggerate the male's body size; females pay more attention to bellows by larger males. Female koalas bellow, though more softly, in addition to making snarls, wails, and screams. These calls are produced when in distress and when making defensive threats. Younger animals squeak and older ones squawk when distraught. When another individual climbs over it,

2666-408: The former are mostly adult females and the latter are males. Resident males appear to be territorial and dominant . The territories of dominant males are found near breeding females, while younger males must wait until they reach full size to challenge for breeding rights. Adult males occasionally venture outside their home ranges; when they do, dominant ones retain their status. As a male climbs

2728-428: The fully furred animal resembles an adult and can look outside the pouch. At six or seven months, the joey weighs 300–500 g (11–18 oz) and fully emerges from the pouch for the first time. It explores its new surroundings cautiously, clutching its mother for support. Around this time, the mother prepares it for a eucalyptus diet by producing a faecal pap that the joey eats from her cloaca. This pap comes from

2790-475: The individual, a koala can walk to the end of a branch or must stay near the base. Each day, koalas eat up to 400 grams (14 oz) of leaves, spread over four to six feeding periods. Despite their adaptations to a low-energy lifestyle, they have meagre fat reserves . Their low-energy diet limits their activity and they sleep 20 hours a day. They are predominantly active at night and spend most of their waking hours foraging. They typically eat and sleep in

2852-480: The koala is denser on the back. Back fur colour varies from light grey to chocolate brown. The belly fur is whitish; on the rump it is mottled whitish and dark. The koala has the most effective insulating back fur of any marsupial and is resilient to wind and rain, while the belly fur can reflect solar radiation. The koala has curved, sharp claws well adapted for climbing trees. The large forepaws have two opposable digits (the first and second, which are opposable to

2914-406: The koala is more generalist than some other marsupial species, such as the greater glider . The koala does not need to drink often as it can get enough water from the leaves, though larger males may additionally drink water found on the ground or in tree hollows. When feeding, a koala reaches out to grab leaves with one forepaw while the other paws hang on to the branch. Depending on the size of

2976-480: The largest for an animal of its size. Koalas can retain food particles for longer fermentation if needed. They are more likely keep smaller particles as larger ones take longer to digest. While the hindgut is relatively large, only 10% of the animal's energy is obtained from digestion in this chamber. The koala's metabolic rate is only 50% of the typical mammalian rate, owing to its low energy intake, although this can vary across seasons and sexes. They can digest

3038-492: The late Pleistocene. Rivers and roads limit gene flow and contribute to the isolation of southeast Queensland populations. In April 2013, scientists from the Australian Museum and Queensland University of Technology announced they had fully sequenced the koala genome . The koala is a robust animal with a large head and vestigial or non-existent tail. It has a body length of 60–85 cm (24–33 in) and

3100-558: The leaves of these trees make up most of their diet. This eucalypt diet has low nutritional and caloric content and contains toxic compounds that deter most other mammals from feeding on it. Koalas are largely sedentary and sleep up to twenty hours a day. They are asocial, only mothers bond to dependent offspring. Adult males communicate with bellows that intimidate rivals and attract mates. Males mark their presence with secretions from scent glands located on their chests. Like other marsupials, koalas give birth to young known as joeys at

3162-558: The modern species, prehistoric koalas had well developed ear structures, which suggests that they also made long-distance vocalisations and had a relatively inactive lifestyle. During the Miocene, the Australian continent began drying out, leading to the decline of rainforests and the spread of open Eucalyptus woodlands. The genus Phascolarctos split from Litokoala in the late Miocene, and had several adaptations that allowed it to live on

3224-483: The now-familiar box was designed for the Christmas season with the innovative idea of attaching a string to hang from the Christmas tree. Until that time, crackers were generally sold only in bulk (the proverbial "cracker barrel") or in large tins. These small cartons, which retailed for 5 cents at the time of their release, were a big hit and are still sold today. The number and variety contained in each box has varied over

3286-484: The other three) that allow them to grip small branches. On the hind paws, the second and third digits are fused , a typical condition for members of the Diprotodontia , and the attached claws (which are still separate) function like a comb. The animal has a robust skeleton and a short, muscular upper body with relatively long upper limbs that contribute to its ability to climb. The thigh muscles are anchored further down

3348-400: The same tree, possibly for as long as a day. On warm days, a koala may rest with its back against a branch or lie down with its limbs dangling. When it gets hot, the koala rests lower in the canopy and near the trunk, where the surface is cooler than the surrounding air. It curls up when it gets cold and wet. It resorts to a lower, thicker, branch during high winds. While it spends most of

3410-431: The small intestine, which digests the eucalyptus leaves to provide most of the animal's energy. A koala sometimes regurgitates the food into the mouth to be chewed a second time. Koalas are hindgut fermenters , and their digestive retention can last 100 hours in the wild or 200 hours in captivity. This is made possible by their caecum —200 cm (79 in) long and 10 cm (3.9 in) in diameter—possibly

3472-518: The spices nutmeg and mace give the basic animal cracker a slightly different character from the Nabisco crackers. Former owner Rodney Stauffer now has his own company, Rodney's Animal Crackers, that also produces animal crackers. Austin, a division of the Keebler Company , also makes a variety of animal crackers. The Austin variety has similar nutritional content and animal shapes. The Austin product

3534-551: The states of Queensland, New South Wales, Victoria, and South Australia . The koala was introduced to several nearby islands. The population on Magnetic Island represents the northern limit of its range. Fossil evidence shows that the koala's range stretched as far west as southwestern Western Australia during the late Pleistocene. They were likely driven to extinction in these areas by environmental changes and hunting by Indigenous Australians . Koalas were introduced to Western Australia at Yanchep in 1938 but that population

3596-473: The time in the tree, the animal descends to the ground to move to another tree, with either a walking or leaping gait. The koala usually grooms itself with its hind paws, with their double claws, but sometimes uses its forepaws or mouth. Koalas are asocial and spend just 15 minutes a day on social behaviours. In areas of higher density and fewer trees, home ranges are smaller and more clumped. Koala society appears to consist of "residents" and "transients":

3658-551: The toxic plant secondary metabolites , phenolic compounds and terpenes due to their production of cytochrome P450 , which neutralises these poisons in the liver . The koala replaces lost water at a lower rate than species such as some possums. It maintains water by absorbing it in the caecum, resulting in drier faecal pellets packed with undigested fibre. The koala's range covers roughly 1,000,000 km (390,000 sq mi), and 30 ecoregions . It ranges throughout mainland eastern and southeastern Australia, including

3720-511: The vocal tract and can be pulled further down. They possess unique folds in the velum (soft palate), known as velar vocal folds, in addition to the typical vocal folds of the larynx. These features allow the koala to produce deeper sounds than would otherwise be possible for their size. The koala has several adaptations for its low nutrient, toxic, and fibrous diet. The animal's dentition consists of incisors and cheek teeth (a single premolar and four molars on each jaw) that are separated by

3782-501: The years. In total, 53 different animals have been represented by animal crackers since 1902. In its current incarnation, each package contains 22 cookies consisting of a variety of animals. The most recent addition, the koala , was added in September 2002 after being chosen by consumer votes, beating out the penguin , walrus and cobra . In 1948, the company changed the product name to its current designation of "Barnum's Animals Crackers". In 1958, production methods changed to improve

In semi-arid climates , they prefer riparian habitats , where nearby streams and creeks provide refuge during times of drought and extreme heat. Koalas are herbivorous , and while most of their diet consists of eucalypt leaves, they can be found in trees of other genera, such as Acacia , Allocasuarina , Callitris , Leptospermum , and Melaleuca .
