The top five reasons that the Tasmanian tiger is endangered?

Answer 1

The Tasmanian tiger is not a tiger, but a carnivorous marsupial (dasyurid), more correctly known as the Thylacine. It was never endangered, as the various conservation status levels were not in force before it became extinct. It was moved to "extinct" status as a result of being hunted as a possible threat to livestock in Tasmania following European settlement. The last known Tasmanian Tiger died in the Hobart Zoo in 1936, and there have been no confirmed sightings since then.

Scientists are divided as to why the Thylacine became extinct on mainland Australia itself. Some evidence points to the introduction of the dingo, which proved to be too much competition for food; other evidence suggests that climate change across the continent led to its extinction. The dingo theory does not explain why Thylacines became extinct on New Guinea, where fossils have been found.
