Tasmanian devil is one of Australia’s most fascinating native mammals and the largest surviving carnivorous marsupial in the world. Despite its relatively small size, this powerful animal has a strong body, large head, sharp teeth and extremely powerful jaws. Its dark fur, white markings and unusual vocalisations have made it one of the most recognizable animals associated with Tasmania.
The scientific name of the Tasmanian devil is Sarcophilus harrisii. It belongs to the family Dasyuridae and is Naturally found in Tasmania. The animal is mainly nocturnal, spending much of the daytime resting inside dens or other sheltered locations and becoming active after sunset.
Tasmanian devils are primarily scavengers, although they can also hunt smaller animals. Their strong jaws allow them to tear through meat, crush bones and consume almost every part of a carcass. This makes them an important part of Tasmania’s ecosystem because they help remove dead animals and recycle nutrients.
The species is currently Endangered, mainly because of Devil Facial Tumour Disease, a contagious cancer that has caused major population declines. Conservation programmes are working to understand the disease, protect wild populations and improve the long-term survival of this remarkable marsupial.

What Is a Tasmanian Devil?
The Tasmanian devil is a carnivorous marsupial native to Tasmania. It is related to other Australian marsupials such as quolls and belongs to the family Dasyuridae.
The animal has a compact and muscular body with a large head, short legs and a thick tail. Although its body resembles a small dog or bear-like animal at first glance, it is biologically very different from placental mammals.
The Tasmanian devil is primarily a scavenger. It can locate animal carcasses using its excellent sense of smell and consume a large portion of the remains. When necessary, it can also hunt smaller animals.
Tasmanian Devil Appearance
The Tasmanian devil has a stocky body covered in dark brown or almost black fur. Most individuals have a white patch on the chest, while some also have white markings around the rump or rear portion of the body. Its head is noticeably large compared with the rest of its body. This large head contains strong jaw muscles that provide the animal with an exceptionally powerful bite.
The ears are small and relatively hairless. They can appear reddish when the animal becomes excited or stressed. The tail is short and thick and can store fat, helping the animal survive periods when food is less abundant.
How Big Is a Tasmanian Devil?
An adult Tasmanian devil generally has a body length of around 55 to 65 centimetres. Its tail can measure 24 to 25 centimetres, while shoulder height is roughly 30 centimetres.
Males are normally larger and heavier than females. Large males can weigh around 12 kilograms or more, although weight varies depending on age, sex, health and food availability. The Tasmanian devil may look small compared with many other carnivores, but its muscular build and powerful jaws make it an extremely strong animal for its size.
Where Do Tasmanian Devils Live?
Tasmanian devils are naturally found in Tasmania, Australia. They are distributed across much of the island and can survive in a wide variety of environments. Their habitats include coastal heathlands, dry forests, mixed woodland, rainforest edges, scrubland and areas close to agricultural land.
They do not depend on one specific type of forest. Instead, they need landscapes that provide enough food, safe shelter and suitable locations for raising young.
Tasmanian Devil Habitat
A suitable Tasmanian devil habitat normally provides both food and protection.
Important habitat features include:
- Coastal heathlands
- Dry forests
- Mixed woodland
- Rainforest areas
- Dense vegetation
- Hollow logs
- Rock shelters
- Abandoned burrows
- Thick scrub
- Areas containing abundant prey and carrion
During the daytime, the animal usually hides in a sheltered location. At night, it leaves its den and searches for food.
Tasmanian Devil Dens
Tasmanian devils spend a large part of the daytime inside protected shelters. They may use hollow logs, rock crevices, dense vegetation and abandoned burrows.
Wombat burrows can also provide excellent shelter. These underground spaces protect devils from harsh weather and provide secure places for females with young. A suitable den is especially important during the breeding season because young devils remain dependent on their mother for several months.
Why Is the Tasmanian Devil Called a Devil?
The animal received its unusual name because of its frightening vocalisations and dramatic behaviour. Tasmanian devils can produce loud growls, screeches, snarls, hisses and harsh coughing sounds. When several animals gather around a carcass, their combined noises can sound particularly frightening.
Their facial displays also contributed to the name. When nervous or threatened, a devil may open its mouth widely and expose its teeth. Despite its reputation, the Tasmanian devil is not constantly aggressive. Many of its dramatic behaviours are associated with fear, feeding competition and communication.
Is the Tasmanian Devil Dangerous?
The Tasmanian devil is a wild animal and should never be approached or handled. Its jaws and teeth are extremely powerful, and it can bite when frightened or threatened. However, Tasmanian devils do not normally hunt humans.
They generally prefer to avoid people and spend most of their active hours searching for food. Their aggressive-looking displays are often defensive or related to competition. Maintaining a safe distance is important whenever a wild devil is encountered.
Tasmanian Devil Diet
Tasmanian devils are primarily scavengers, but they are also capable predators. Their diet is highly flexible and changes according to the availability of food. They may eat wallabies, wombats, possums, small mammals, birds, reptiles, amphibians and insects.
They can also consume dead livestock when carcasses are available. One of their most impressive abilities is consuming tough parts of a carcass. Their powerful jaws allow them to break bones and eat fur, skin and other tissues.
What Do Tasmanian Devils Eat?
| Food Category | Examples |
| Mammals | Wallabies, wombats, possums and small mammals |
| Birds | Birds and bird remains |
| Reptiles | Lizards and other reptiles |
| Amphibians | Frogs and other amphibians |
| Insects | Various insects and invertebrates |
| Carrion | Dead animals and carcasses |
| Livestock Remains | Sheep and cattle carcasses |
| Other Animal Material | Meat and available animal remains |
How Does a Tasmanian Devil Feed?
Tasmanian devils are famous for their noisy feeding behaviour. When a large carcass is discovered, several individuals may arrive at the same time. They can growl, screech, bare their teeth and push against each other while competing for access to the food. This behaviour can look like an uncontrolled fight, but many of these displays are actually forms of communication. They help establish dominance and reduce the need for prolonged physical conflicts. Once an individual gets access to the carcass, its powerful jaws allow it to consume large quantities of food.
Why Are Tasmanian Devils Good Scavengers?
The Tasmanian devil has several physical characteristics that make it an excellent scavenger. Its powerful jaws can break through bones, while its sharp teeth can tear through tough tissues. Its strong sense of smell helps it locate carcasses, even when they are not immediately visible. Because the devil can consume so much of a carcass, very little usable food may remain after a feeding event. This makes the species an important part of Tasmania’s natural recycling system.
Tasmanian Devil Behaviour
Tasmanian devils are primarily nocturnal. They normally rest during the daytime and become active after sunset. At night, they travel through their home ranges while searching for food. Some individuals can travel many kilometres in a single night, especially when food is scarce. They are generally solitary while moving around, but several devils can interact when a valuable food source is available.
Tasmanian Devil Social Behaviour
Tasmanian devils are not highly social animals, but they are not completely solitary either. Several individuals may gather around a carcass and communicate through sounds, body posture and facial displays. Young devils behave differently from adults. They spend considerable time playing with one another by wrestling, chasing, biting and climbing. These activities help them develop the skills needed for adult life.
Tasmanian Devil Sounds
The Tasmanian devil is famous for its wide variety of vocalisations.
Common sounds include:
- Growling
- Screeching
- Snarling
- Hissing
- Squealing
- Cough-like noises
- Warning calls
- Feeding sounds
The noises are particularly noticeable at night. They may sound frightening to humans, but they are normal forms of communication. Vocalisations are particularly important during feeding, breeding and encounters between competing individuals.
Why Do Tasmanian Devils Open Their Mouths?
The famous open-mouth display of the Tasmanian devil is often misunderstood. When frightened or nervous, a devil may open its mouth widely and show its teeth. This makes the animal appear aggressive, but the behaviour can actually be a response to fear or uncertainty. Such displays may help prevent physical confrontation by warning another animal that the devil feels threatened.
Tasmanian Devil Reproduction
Tasmanian devils generally breed during the late summer and autumn months. After mating, the female has a very short gestation period of approximately 21 days. She then gives birth to many extremely small young. The newborns are highly underdeveloped and must immediately crawl toward the mother’s pouch.
Tasmanian Devil Babies
A female can give birth to approximately 20 to 30 young, although the number can vary. The mother has only four teats, so only four young can normally survive the early pouch stage. The newborns compete to reach the pouch and attach themselves to a teat. The young that successfully establish a connection continue developing inside the pouch.
Tasmanian Devil Pouch
The surviving young remain inside the mother’s pouch for approximately four months. During this time, they remain attached to the teats and depend completely on their mother. As they grow larger, they gradually begin leaving the pouch for short periods. They then spend more time inside a secure den while their mother searches for food.
Tasmanian Devil Life Cycle
| Life Stage | Description |
| Birth | Many extremely small young are born |
| Pouch Entry | Newborns crawl into the mother’s pouch |
| Early Development | Young attach to one of four teats |
| Around 4 Months | Joeys begin leaving the pouch |
| Den Stage | Young continue growing in a protected den |
| Weaning | Young gradually become independent |
| Juvenile Stage | Young develop hunting and survival skills |
| Maturity | Young eventually become capable of reproduction |
How Long Do Tasmanian Devils Live?
Tasmanian devils generally have a relatively short lifespan compared with many larger mammals. Wild individuals can live for several years, although disease, road accidents, injuries, food shortages and other environmental pressures can shorten their lives. Devil Facial Tumour Disease has also affected the age structure of many wild populations because infected animals can die before completing several breeding seasons.
Tasmanian Devil Conservation Status
The Tasmanian devil is classified as Endangered. The species has experienced major population pressure because of Devil Facial Tumour Disease. Road mortality and habitat-related pressures are additional concerns. Conservation efforts now focus on disease research, population monitoring, habitat protection, genetic management and breeding programmes.
What Is Devil Facial Tumour Disease?
Devil Facial Tumour Disease, commonly called DFTD, is a contagious cancer that affects Tasmanian devils. The disease often produces tumours around the face and mouth. As the tumours grow, they can interfere with feeding and cause serious health problems. The disease is unusual because cancer cells themselves can be transferred from one animal to another.

How Does Devil Facial Tumour Disease Spread?
DFTD spreads primarily through direct physical contact between devils. Tasmanian devils bite one another during fighting, mating and disputes over food. When an infected animal bites another devil, living tumour cells can enter the wound. The transferred cancer cells can then grow inside the new host. This unusual method of transmission makes the disease particularly difficult to control in wild populations.
Effects of Devil Facial Tumour Disease
DFTD can cause severe facial and oral tumours. As tumours grow around the mouth, infected animals may have difficulty eating. Their body condition can decline, and advanced disease can eventually lead to death. The disease has caused severe population declines in many areas of Tasmania, making it one of the most important wildlife conservation challenges associated with the species.
Other Threats to Tasmanian Devils
Although DFTD is the most serious modern threat, Tasmanian devils face several other challenges.
Road Accidents
Because devils are scavengers, they may approach roads to feed on dead animals. This puts them at risk of vehicle collisions.
Habitat Loss
Development and land-use changes can reduce suitable habitat and affect access to food and safe denning areas.
Historical Persecution
Tasmanian devils were historically considered pests and were deliberately killed by settlers. Bounty systems contributed to population pressure before the species received legal protection.
Food Availability
Changes in prey numbers and carrion availability can affect survival and breeding success.
Tasmanian Devil Conservation Efforts
Conservation programmes are working to protect Tasmanian devils through a combination of research, monitoring and population management.
Important conservation activities include:
- Monitoring wild populations
- Studying Devil Facial Tumour Disease
- Protecting natural habitat
- Maintaining genetic diversity
- Supporting conservation breeding
- Managing disease-free populations
- Reducing road mortality
- Studying reproductive behaviour
- Monitoring released animals
- Increasing public awareness
Maintaining genetically diverse populations is particularly important because genetic variation may help the species respond to disease and environmental changes.
Tasmanian Devil and the Ecosystem
The Tasmanian devil has an important role as a scavenger and predator. By consuming dead animals, it helps remove carcasses from the landscape and contributes to natural nutrient recycling. Its feeding behaviour can also influence other scavengers because it competes for carrion. A healthy devil population therefore contributes to the balance of Tasmania’s food web.
Tasmanian Devil and Agriculture
Tasmanian devils can occur close to agricultural land. Farms may provide access to native prey as well as livestock carcasses. Devils can sometimes help by consuming dead animals that might otherwise remain in the environment. However, people should never deliberately feed wild devils. Artificial feeding can change natural behaviour and increase the likelihood of conflict.
Tasmanian Devil and Humans
Tasmanian devils generally avoid humans and are more interested in finding food than interacting with people. If a devil is encountered, the best response is to maintain distance and allow it to move away naturally. People should never attempt to catch, feed, touch or corner a wild devil.
Where Can You See a Tasmanian Devil?
Tasmanian devils can be found across Tasmania, although seeing one in the wild can be difficult because of their nocturnal lifestyle. Visitors may have opportunities to observe devils at wildlife sanctuaries and conservation centres, where the animals can be studied and viewed in controlled environments. Wild observations require patience because devils usually become active after sunset.
Best Time to Observe Tasmanian Devils
The best opportunity to observe a Tasmanian devil’s natural behaviour is generally during the evening and nighttime. During daylight, the animal usually rests inside a den or hidden vegetation. Anyone travelling through Tasmania after dark should also drive carefully because devils and other wildlife may cross roads.
Tasmanian Devil Photography
Tasmanian devils are interesting subjects for wildlife photography because of their distinctive faces, dark fur and unusual behaviour. Photographers should maintain a safe distance and avoid disturbing animals. Wildlife photography should never involve feeding, chasing, trapping or deliberately frightening a devil for a photograph.
