The Tasmanian tiger is an intriguing marsupial that became extinct on September 7, 1936. Another name for the Tasmanian tiger is thylacine, and its scientific name is cynocephalic thylacine . The scientific name of the Thylacine means "dog-headed mammal", (Strauss, 2017). The thylacine is a shy and secluded animal that avoids contact with humans, but would be captured without any struggle and would die randomly because the animal would go into shock. They hunted alone or with a partner, and mostly at night. They were carnivores and ate small marsupials such as wallabies and possums. The Tasmanian tiger could open its mouth at an angle of about 90 degrees, but it had a weak jaw, which is why it ate small marsupials. Thylacines were about the same size as a dog and a wolf. Female Tasmanian Tigers had pouches, "which they use to incubate and protect their prematurely born young... Male Tasmanian Tigers also had pouches, which covered their testicles when circumstances required, presumably when outside it was bitterly cold or when they were fighting with other thylacine males for the right to mate with females.”,(Strauss,2017). Tasmania is related to the numbat, the Tasmanian devil and the banded anteater. They make a loud yelp and bark like a dog when excited or anxious, like many other animals the Tasmanian tiger gets scared or excited and tends to jump hopping like a wing. The disappearance of the thylacine is a mystery and has not been fully proven. The date when the last known Thylacine, "died in captivity in September 1936, more than 80 years ago", (Ciaccia,2017) . The last thylacine has died at Beaumaris Zoo in Hobart, Australia. The Dingo was a huge cause of extinction for the Tasmanian Tiger, because they looked at each other as prey and ate each other. As for humans being the cause of their extinction, humans took over their land and homes, captured thylacines, and would bring diseases to the animals that would spread to other animals and the thylacine family. They had a lifespan of 5-7 years in the wild and about 9 years in captivity. The oldest bones found from the Thylacine date back 2,200 years. The Tasmanian tiger population, “It is estimated that there were approximately 5,000 thylacines in Tasmania when Europeans settled the area…”, (Bradford,2017). They populated Tasmania, Australia, and spread further into the area, and fossils are being discovered in those nearby areas. The cause of the extinction of this particular animal has led some scientists to question whether or not the thylacine is extinct due to thylacine sightings. To conclude, the thylacine had an interesting extinction and makes some people believe that it wasn't
