Transcript of The Tasmanian Tiger and Tasmanian Devil

The Tasmanian Tiger and Tasmanian Devil
What is the Tasmanain Devil?
What is the difference between these animals?
The Tasmanian tiger was a marsupial that looked similar to a dog with a straight downward pointed tail, they also had stripes running down their spine but the stripes did not reach its belly. The Tasmanian tiger is also about 1.8m long with a long tail. The Tasmanian devil is a small marsupial that only grows to about 0.7m long, with short legs and a barrel shaped body. They have a snout that has sharp teeth, they both have a very sharp bite. The Tasmanian Devil is not extinct compared to the already extinct Tasmanian Tiger.
What is the Tasmanian Tiger (Thycaline)
The Thylacine (most commonly known as the Tasmanian Tiger but also known as the Tasmanian Hyena and Tasmanian Wolf) is a carnivorous marsupial that lived in mainland Australia and Tasmania. The last Thylacine died in a Hobart Zoo on the 7th of September 1936. In northern Queensland fossils of Thylacine were found and were more than 30 million years old. The Thylacine was about 1.8m long and its tail was 53 cm long. It would have been 58cm tall and weigh 30kg, about the size of a German Shepard. It was grey and black in colour with 16 stripes on its back. It had the same shape as a dog but the back and tail resembled similarities with a kangaroo, it also had very short legs. The Thylacine had teeth like a dog but with more incisor teeth. The Tasmanian tiger had a strange characteristic to open its mouth extremely wide (at 120 degrees). The Thylacine was a nocturnal animal that hunts only at night their diet comprised of Wallabies, rats, birds, echidnas, Tasmanian Devils,rabbits and sheep, (the last two animals were introduced by the English). The Tasmanian Tiger is a marsupial, which means that the females would carry the babies in a pouch, which would open in the rear.
The Tasmanian Devil is also a carnivorous marsupial, it is only found in Tasmania. It is the world's largest surviving carnivorous marsupial, the devil has a thick build, with a large broad head and short, thick tail. The fur is mostly black, but white markings often occur on the rump and chest. Body size varies depending on the diet and habitat. Adult males are usually larger than adult females. Large males weigh up to 12 kg, and stand about 30 cm high at the shoulder. The Tasmanian devil is a nocturnal animal spending days in bushes or in a hole. Adult devils may eat their young if they are extremely hungry, they can climb trees and also they have been known to swim across rivers. The Tasmanian devil’s diet includes wombats, domestic mammals, sheep and road kill. Before the Tasmanian Tiger became extinct the Devil would eat their young when left alone in burrows. In the mid 1990’s the Tasmanian Devil population was at over 100,000 but a study from 2008 showed that there are only 10-15 thousand left in the wild leaving its conservation status at endangered.
Why is the Tasmanian Tiger extinct?
On 7 September 1936, the last known Tasmanian Tiger died at the Hobart Zoo. This was the first known species of animal to become extinct in Tasmania. In 1824, settlers introduced sheep to Tasmania. The Thylacine, more used to hunting swift moving prey such as kangaroos and birds, found this as an easier form of sustenance. In 1830, the Van Diemen's Land Company offered a bounty for the head of each Tiger. The Tasmanian government in 1888 offered an increased bounty. Between then and 1909, the government paid more than 2,180 bounties. By 1910, the formerly common Thylacine was considered rare and zoos from all over the world were keen to have one in their collection. Unfortunately, not many thylacines lasted long in captivity. Habitat destruction and a a viral like disease further decreased the population until the last thylacine was captured in 1933. This animal was kept at Hobart Zoo until it died in September 1936. The accepted story is that the day-shift keeper forgot to lock the Tasmanian Tiger up in its hut one night and it died.
How can we conserve the Tasmanian Devil
The Tasmanian Devil's are slowly becoming extinct from our natural habitats in Tasmania the reason being for this tragedy is a disease named (
DFTD
) or Devil Facial Tumor Disease.Devils usually die within a few months of contracting
DFTD
Tasmanian Devils usually find it very difficult to eat due to the facial tumors. In diseased areas nearly all mature Devils became diseased, in populations which were observed over a few years the population has declined by 97%.To help soppurt the fight to end the Tasmanian Devils struggle with this disease you can make a donation to a charity that supports the Tasmanian Devil, run a fandraiser for the Tasmanian Devil, Sponsor an Event. $135 can house a Tasmanian Devil for a week, $584 can house a Tasmanian Devil for a month and $7000 can house a Tasmanian Devil for a year.
