Tasmanian Devil: The Fierce Marsupial of Australia
The Tasmanian devil, scientifically known as Sarcophilus harrisii, is a carnivorous marsupial that is native to the Australian island of Tasmania. These small, furry creatures have a reputation for being fierce and aggressive, but they are also incredibly unique and fascinating. Despite being classified as an endangered species, the Tasmanian devil has managed to capture the hearts of many animal lovers around the world. In this article, we will explore the history, evolution, physical characteristics, behavior, diet, and threats faced by the Tasmanian devil.
Scientific Name and Classification:
The Tasmanian devil belongs to the family Dasyuridae, which includes other carnivorous marsupials such as quolls and the extinct thylacosmilids. The genus name, Sarcophilus, means "flesh lover" in Greek, which is fitting for this species. The Tasmanian devil was named after the famous Scottish naturalist, Sir Edward Home, who named it Dasyurus laniarius in 1830. However, in 1841, Richard Owen, an English paleontologist, reclassified it under the new genus Sarcophilus.
The Tasmanian devil is a marsupial, which means that it gives birth to underdeveloped young that continue to develop outside the womb in a pouch. This species belongs to the order Dasyuromorphia, which includes other carnivorous marsupials such as quolls, dunnarts, and the extinct thylacosmilids.
The Tasmanian devil is one of the oldest surviving marsupials, with fossils dating back to the early Miocene epoch (23-16 million years ago). The species was once widespread across the Australian mainland, but due to the arrival of dingoes and human hunting, it became restricted to Tasmania around 4000 years ago.
Evolution and Origins:
The Tasmanian devil is thought to have evolved from a common ancestor with quolls around 10-15 million years ago. The species is believed to have become isolated in Tasmania around 10,000 years ago, which led to the development of its unique characteristics. The Tasmanian devil is the largest carnivorous marsupial in the world and is known for its strong bite and powerful jaws.
The Tasmanian devil has a stocky build with a short, black fur coat and a white stripe on its chest. It has a large head and powerful jaws, which are capable of crushing bones. Tasmanian devils have sharp teeth and a keen sense of smell. They also have a keen sense of hearing and are able to detect sounds up to 2.5 kilometers away.
Tasmanian devils are solitary animals but are known to form communal feeding groups. They have a hierarchical social structure, with dominant individuals eating first and subordinate individuals waiting their turn. Tasmanian devils are also known for their vocalizations, which include growling, screeching, and snarling.
Anatomy and Appearance:
The Tasmanian devil is a medium-sized mammal, with males being larger than females. They have a robust build and powerful legs, which make them fast runners. The Tasmanian devil has a distinctive black coat with white markings on its chest and a pointed snout. They also have a long, thin tail that is about half the length of their body.
Distribution and Habitat:
The Tasmanian devil is found only in Tasmania, which is an island state of Australia. They are known to inhabit a variety of habitats, including forests, grasslands, and scrublands.
Population – How Many Are Left?
The Tasmanian devil is currently classified as an endangered species, with an estimated population of around 10,000 individuals. The species has experienced a significant decline in population in recent years due to a contagious cancer known as devil facial tumor disease (DFTD). DFTD has spread rapidly throughout the Tasmanian devil population, causing a decline of up to 80% in some areas.
The Tasmanian devil is a medium-sized marsupial, with males weighing between 6 and 8 kilograms and females weighing between 4 and 6 kilograms. They measure up to 30 inches in length, including their tail, which is around 12 inches long.
The weight of Tasmanian devils varies depending on their gender and age. Males are generally larger than females, with males weighing between 6 and 8 kilograms and females weighing between 4 and 6 kilograms.
Behavior and Lifestyle:
Tasmanian devils are nocturnal animals, meaning that they are most active at night. They are solitary hunters and are known to scavenge for food. Tasmanian devils are also known for their aggressive behavior and have been observed fighting over food and territory.
Tasmanian devils breed once a year, with mating occurring between March and May. Females give birth to 20-30 underdeveloped young that continue to develop in the mother's pouch. The young stay in the pouch for around four months before becoming independent.
Tasmanian devil babies are called joeys and are born blind and hairless. They continue to develop in their mother's pouch for around four months before becoming independent.
The lifespan of Tasmanian devils in the wild is around 5-6 years, although some individuals have been known to live up to 8 years. In captivity, they can live up to 8-10 years.
Diet and Prey:
Tasmanian devils are carnivorous and feed on a variety of prey, including wallabies, possums, birds, reptiles, and insects. They are also known to scavenge for food and will eat carrion.
Predators and Threats:
The main threat to Tasmanian devils is DFTD, which has caused a significant decline in population in recent years. Other threats include habitat loss, roadkill, and persecution by humans.
Relationship with Humans:
Tasmanian devils have a mixed relationship with humans. While they are not typically aggressive towards humans, they have been known to attack when provoked or threatened. Tasmanian devils are also hunted for their fur and have been persecuted by humans in the past.
- Tasmanian devils are capable of eating up to 40% of their body weight in a single meal.
- The Tasmanian devil is the largest carnivorous marsupial in the world.
- Tasmanian devils are able to climb trees and swim.
- Tasmanian devils are known for their loud, aggressive vocalizations, which have earned them the nickname "the sound of hell".

Q: Can Tasmanian devils be kept as pets?
A: No, Tasmanian devils are wild animals and should not be kept as pets.
Q: Can Tasmanian devils be found anywhere other than Tasmania?
A: No, Tasmanian devils are only found in Tasmania.
Q: Are Tasmanian devils endangered?
A: Yes, Tasmanian devils are classified as an endangered species.
The Tasmanian devil is a unique and fascinating animal that is found only in Tasmania. This carnivorous marsupial has a distinct appearance and a reputation for being aggressive, but it also plays an important role in the ecosystem. Unfortunately, the Tasmanian devil is currently facing a significant threat in the form of DFTD, which has caused a decline in population in recent years. Efforts are being made to protect and conserve this endangered species, but more needs to be done to ensure their survival in the wild.
Overall, the Tasmanian devil is a remarkable animal that deserves our attention and protection. Its unique biology and behavior make it a valuable part of Tasmania's natural heritage, and its plight highlights the importance of conservation efforts for all endangered species. By working together to protect the Tasmanian devil, we can ensure that this iconic animal continues to thrive in the wild for generations to come.
