The Tasmanian Tiger is actually called the Thylacine. The the Thylacine was a predator at the top of the food chain. This carnivore would feed on kangaroos, wombats, birds, wallabies, possums among other Australian animals. This was indeed a predator that had a pouch for their young and is thought to be the largest marsupial predator to have lived in recent times. Unlike most pouch-bearing animals both the female and the male had a pouch.
The male didn’t carry little babies in his pouch though as it simply acted as a protective layer for his vital organs. This dog-like animal was about 1 m (3′) long with a tail length adding an extra 50-65 cm (1.6-2.1′) to their dimensions. Their teeth were very similar to the various dog species while their feet were padded. The pouch of the female was at the base of her tail while the males was protecting his organs. The first major blow to their population was the sudden competition with the exotic dingo, which was brought over by aborigines.
Once the European settlers came over the Tasmanian Tiger was doomed due to bounty hunting, habitat destruction and competition with domestic dogs. There have been numerous sightings of the Thylacine, however, most of these seem comparable to the famous sightings of the Loch Ness or Big Foot. As well, there is an ongoing project to clone this extinct animal from some recovered DNA.
