What You'll Learn
The Tasmanian devil
Tasmanian devils are primarily nocturnal and prefer to eat carrion (dead animals). They will also prey on small birds, snakes, fish, and insects. Despite their name, Tasmanian devils are typically solitary creatures. However, they will sometimes come together to feed on a carcass, which often leads to fighting as they jockey for position. Tasmanian devils have a keen sense of smell, which they use to find food. They can travel up to 16 km in one night in search of a meal.
The name "Tasmanian devil" comes from the late-night, 'otherworldly' howls heard by early European settlers. The binomial name, Sarcophilus harrisii, means "Harris's flesh-lover", referring to its carnivorous nature. The Tasmanian devil is related to quolls and distantly related to the thylacine, another Australian marsupial. It is believed that the Tasmanian devil's peculiar gait may be due to adaptations that allowed its possible ancestors to climb trees in search of food.

The Common Brushtail Possum
In Australia, the common brushtail possum is a protected species, but it is considered a major agricultural and conservation pest in New Zealand, where it was introduced in the 1830s-1850s to establish a fur industry. The species is more densely populated in New Zealand than in Australia due to the latter's fragmented eucalypt forests and higher number of predators, including humans, tiger quolls, dogs, foxes, cats, goannas, carpet snakes, and powerful owls. The northern subspecies of the common brushtail possum has declined substantially, with studies showing reductions in the extent of occurrence and occupied environmental space.

The world's largest carnivorous marsupial
The Tasmanian devil is the world's largest carnivorous marsupial. It is about the size of a small dog and is known for its blood-curdling screams, eerie growls, black colour, foul odour, and aggressive behaviour. The species has the strongest bite-for-size of any other mammal and will even bite through metal. When eating their prey, they will devour the bones as well. Due to habitat destruction and a contagious tumorous cancer, the Tasmanian Devil has been listed as an endangered species.
The Tasmanian devil is a unique and fascinating creature native to Tasmania, an island south of mainland Australia. While it may be known for its intimidating characteristics, such as its powerful bite and aggressive behaviour, it plays an important role in the ecosystem by primarily feeding on dead animals.
The Tasmanian devil's scientific name is Sarcophilus harrisii, which translates to "Harris's flesh-lover." This name was given by early European settlers who observed the animal's scavenging behaviour. The species is considered a keystone predator, which means that it has a significant impact on its ecosystem.
Despite its fearsome reputation, the Tasmanian devil faces several threats in the wild. In addition to habitat destruction and disease, devil numbers have also been affected by a mysterious condition called "devil facial tumour disease" (DFTD). This disease is characterised by the growth of tumours around the mouth and face, which can interfere with the animal's ability to eat and breathe. Conservation efforts are currently underway to protect this iconic species and prevent its decline.
The Tasmanian devil is an iconic symbol of Australia's unique wildlife and an important part of the country's cultural heritage. While it may be known for its intimidating characteristics, efforts are being made to ensure the survival of this fascinating creature for future generations to appreciate and study.

The blood-curdling screams of the devil
The Tasmanian devil is a unique creature, to say the least. About the size of a small dog, this marsupial is known for its blood-curdling screams, eerie growls, black colour, foul odour, and aggressive behaviour. It is the world's largest carnivorous marsupial, native to the island of Tasmania, just south of mainland Australia. With the strongest bite-for-size of any mammal, these devils can bite through metal, and they devour their prey, bones and all.
The Tasmanian devil's eerie growls and blood-curdling screams have earned it its name. But these sounds are not the only scary thing about this creature. Its aggressive behaviour and strong bite make it a formidable opponent for any who cross its path. The devil's black colour and foul odour add to its overall sinister aura.
The devil's diet consists mainly of dead animals, which it consumes bones and all, leaving nothing to waste. This carnivorous creature is an efficient eater, ensuring that every part of its prey is utilized. However, it is not just the devil's eating habits that are of concern. Its aggressive nature can also be quite intimidating.
The Tasmanian devil is an endangered species due to habitat destruction and a contagious tumorous cancer that has spread through the population. Despite their intimidating characteristics, these devils are in need of protection and conservation efforts to ensure their survival for future generations.
So, while the blood-curdling screams and eerie growls of the devil may strike fear into the hearts of those who hear them, it is important to remember that these creatures are facing significant threats to their existence. Conservation efforts are crucial to ensure the continued survival of these unique and fascinating Australian animals.

The devil's aggressive behaviour
The Tasmanian devil is a unique Australian marsupial, known for its aggressive behaviour and fearsome reputation. The size of a small dog, this black, carnivorous marsupial is the largest of its kind in the world. Its aggressive behaviour is well documented, and it is known to emit eerie growls and blood-curdling screams.
Tasmanian devils have an incredibly strong bite, the strongest bite-force relative to their size of any mammal. This powerful bite enables them to bite through metal, and they will devour their prey, bones and all. Their aggressive nature is not limited to hunting, and they will fiercely defend their food from other devils. This behaviour has earned them their devilish name, and they are often described as terrifying.
The Tasmanian devil's aggressive behaviour is driven by its need to survive and protect itself. They are scavengers and will fight for food, especially the opportunity to eat fresh meat, which is rare for them. They are also known to be highly protective of their young, and their aggressive behaviour may be a form of defence mechanism to protect their offspring.
The Tasmanian devil is an endangered species, and their aggressive behaviour may be a contributing factor. They are susceptible to a contagious tumorous cancer, which has spread through the population. This cancer is believed to be transmitted through their aggressive interactions with each other, as they frequently bite each other during fights.
Despite their aggressive nature, Tasmanian devils are fascinating creatures and an important part of the Australian ecosystem. Their aggressive behaviour is a crucial aspect of their survival strategy, and it is important to understand and respect their place in the wild.
