Facts you didn't know about the Quoll animal

Quiet, it may appear small and shy, but its modest size hides a formidable temperament.

The quoll is one of many unique marsupials found nowhere else but in Australia and New Guinea. Like many other marsupials, including the kangaroo, the Quoll's evolution is a result of the geographical isolation and diversity of the region. But for the past few centuries, the animal has been under siege in its native habitat. Fragile and vulnerable, these unique creatures may need the help of conservationists to survive.

Interesting facts about Quoll

Captain James Cook encountered the Quoll on his first voyage to the Australian coast in 1770. He seems to have collected several specimens in the wild.

Once called a 'cat' by European settlers, the term Quoll became widely accepted in the 1960s. It is derived from one of the aboriginal names encountered by Cook on his first voyage.

Quolls are nocturnal in nature. They do most of their hunting and foraging at night.

Scientific name of Quoll

Dasyurus is the scientific name for the entire genus quoll. Translated from Latin, the name means "hairy tail", which reflects the most important characteristic of the animal. The Quoll is closely related to the Tasmanian devil, the dunnart and many other small marsupials.

The genus Dasyurus comprises six living species. Four of these species live in Australia or Tasmania: the eastern koll, the northern quoll, the western kool and the tiger cole (also known as the spotted or spotted-tailed quoll). The two remaining species live in New Guinea: the bronze quoll and the New Guinea quoll.

Based on genetic analysis, scientists conclude that the first quolls evolved about 15 million years ago and that the six living species can trace their origins to a common ancestor about four million years ago. Some extinct species have been identified from the fossil record.

Quoll's appearance and behaviour

Quoll is a marsupial carnivore. It is distinguished by its long nose, pink nose, hairy tail, large ears, sharp teeth, elongated body, brown or black coat with white spots. The distinctive feature of the marsupial is the large abdominal pouch that carries and protects the underdeveloped offspring. However, only the tiger quoll has a true pouch. The other five species have skin folds facing the tail. These folds develop during the breeding season.

The quoll displays a wide range of different sizes. The smallest species, the northern quoll, is the size of a kitten, while the eastern and western quolls are the size of an adult cat. The impressive dwarf tiger (also known as the spotted quoll) dwarfs all others. Spanning 30 inches from head to toe (plus an additional 15-20 inches with the tail fully extended), it is one of the largest carnivorous marsupial species in all of Australia. Males tend to be larger than females on average, but there is little sexual dimorphism, meaning it is difficult to distinguish the sexes based on appearance alone.

Quolls are solitary and reclusive creatures that tend to hunt, feed and live alone. Interactions outside of the mating season are limited, but do occur in certain areas. For example, the quolls seem to have the equivalent of public toilets. Located around rocky outcrops, these large areas may serve as a gathering place. Females also appear to share dens with other members of their species, both males and females. However, males rarely share dens with each other.

Quolls will do just about anything in the house: rock crevices, hollow trees or logs, underground burrows and even termite mounds. They spend most of their days resting in the den but may occasionally come out to enjoy the sunshine. Each Quoll has a small basic range as well as a larger range that can extend more than a mile in either direction. They will defend their territory against outside intruders and, despite their size, can be very aggressive. Males tend to have larger litters than females.

Quoll home

The quoll inhabits the forests, woodlands and grasslands of the Australian region. Their habitats generally receive moderate to heavy rainfall. Each species has adapted to a slightly different area.

Eastern Cole or Dasyurus viverrinus: This species was once widespread throughout much of southeastern Australia and now resides almost exclusively on the island of Tasmania, where it conflicts with the Tasmanian Devil.

Tiger Cole or Dasyurus Spotted: Also known as the spotted quoll (because the spots extend to the tail), this species inhabits the dense forests of eastern Australia, including Tasmania.

Northern Cole or Hallucinogen Dasyurus: Evidence indicates that this species once inhabited most of northern Australia. It is now restricted to a few discontinuous points in the northern parts of three Australian states: Western Australia, the Northern Territory and Queensland.

Western Cool or Dasyurus geoffroii: This species once inhabited nearly 70% of Australia. It is now confined to a small corner of Western Australia.

New Guinea Quoll or Dasyurus albopunctatus: This species has a wide and continuous distribution in the northern half of New Guinea. Habitats include grasslands, rainforests and moss forests at various altitudes.

Bronze Quoll Odasaurus spartacus: This species occupies a narrow range of savannahs and grasslands in the southern part of New Guinea.

Quoll's diet

Quoll is an opportunistic scavenger that consumes almost anything it can find, dead or alive. Their most common diet includes insects, birds, mice, rats, lizards and frogs. The larger species of quoll are also known to consume birds and medium-sized mammals such as hedgehogs, rabbits and possums. Although carnivorous, the quoll may also occasionally eat fruit and vegetables.

They spend most of their time foraging on land, but quolls can also be very adept at climbing. They are known to climb trees in search of birds to hunt. They usually travel a few kilometres a night in search of food.

Suppression of predators and threats

The Quoll faces many dangerous threats in the wild. When introduced to Australia, non-native animals such as foxes and cats have had a destabilising effect on the Quoll population. Not only do they prey directly on the Quoll, but they compete with the Quoll for food and resources. Other potential sources of danger include snakes, dingoes, eagles and owls.

Adults may bite and scratch to defend themselves, and if all else fails, they may escape and hide. Young pups are the most vulnerable to predation, as they are entirely dependent on their mother for protection.

The introduction of the poison frog to Australia in 1935 had a devastating effect on the local population. The cane frog was originally imported to Australia from the Americas and was thought to be effective in controlling pests, but had the unintended effect of poisoning and killing predators. The toad is still found in much of northeastern Australia, threatening the remaining populations. Quols do not appear to have any natural resistance or immunity to the toxin. Its only foolproof defence is to avoid the frog completely.

Quolls face another threat from human encroachment. As they roam human territory, they can fall victim to dog attacks, poisoned bait, car accidents and deliberate human persecution. Although they are known to feed on insects and pests that destroy crops, they have also caused damage by raiding poultry farms, leading to retaliation by farmers. Habitat loss due to logging, agriculture and urbanisation has also restricted the natural range of the kool.

In the future, gallstones may be particularly vulnerable to global climate change. With forest fires burning more intensely across the country, climate change could destroy large parts of the kool's natural habitat.

Quoll breeding, children, age

The breeding season begins in autumn or winter in Australia from April to July. Quoll mating can be a long and dangerous affair full of biting and gnawing. For example, a tiger leopard can take about eight hours to fully mate, which is largely harmful to the female. Animals may have several partners during the mating season.

Some species can produce up to 30 offspring at a time, but only six to eight young tend to survive, as this is the maximum a mother can nurse at a time. The remaining pups must die.

The gestation period is about three weeks. Undeveloped puppies spend the first few months of their lives hidden in their mother's pouch, feeding on milk from their nipples. As they grow, the young puppies attach themselves to the mother's belly and then to her back. It takes about five months to reach full independence and about a year to become sexually mature.

The typical lifespan is between two and five years, depending on the size of the species. Few individuals survive the first or second breeding season. The maximum documented lifespan in captivity was about seven years.

Quoll residents

Quolls used to cover most of Australia, but the arrival of European settlers in the late 18th century began a period of decline for the animals. Now they are tethered to the outskirts of Australia. Because the sedids are so adept at hiding, conservationists may find it difficult to count and track them. However, as far as we know, the Quolls are in an unstable state. The Eastern and North Cole are endangered. The remaining species are either vulnerable or near threatened. According to the International Union for Conservation of Nature (IUCN) Red List, each species has about 10,000 to 15,000 individuals remaining.

Conservationists have successfully bred the quoll in captivity to save the species from destruction and to provide relief populations. As long as this protected group remains, conservationists can prepare the quoll for reintroduction into its former habitat. If something goes wrong, they can adapt their strategy to compensate.

East Quoll is an interesting case study. It largely disappeared from mainland Australia in the 1960s, apart from a few sightings. The species is now protected in Tasmania, where it faces fewer threats. In 2016, conservationists began reintroducing the species to mainland Australia for the first time in nearly 50 years. The snails showed promising signs of recovery when they began producing their first batch of offspring.

The removal of foxes and frogs (along with improved human awareness and monitoring) has allowed the herd to return to parts of its former range, but the challenge for animals in captivity or relative safety is that they may have difficulty identifying threats once introduced to more hostile areas. areas where animals have a greater chance of surviving if you learn to be wary of threats beforehand.
