The Tasmanian tiger is not actually a tiger but a marsupial with stripes

The Tasmanian Tiger, also called the Tasmanian Wolf, is a large marsupial native to Tasmania. Most scientists believe it to be extinct, however each year there are about a dozen unconfirmed sightings in remote areas of the state, and several reported sets of Tiger tracks. In January 1995, a Parks and Wildlife Service officer observed a Tiger in the Pyengana region of eastern Tasmania, and being the most reliable sighting in some time, the government launched an investigation to possibly confirm the existence of the Tiger.

The Tiger was about 5 feet (1.5 m) long, and had light brown fur with dark stripes across its lower back. Tasmanian Tiger jaws are believed to open wider than any other mammal.

Tigers were common toward the start of the century but were hunted extensively because they threatened sheep. Tiger skins and a preserved Tiger can be seen at the Tasmanian Museum and Art Gallery in Hobart. Footage of Tasmanian Tigers can be viewed at the Tasmanian Devil Park in Taranna (near Port Arthur).

Tasmanian Tigers are also known as thylacines after their Latin name, Thylacinus cynocephalus.

Croc

Some crocodiles lie with their mouths open and allow birds to safely pick food particles and parasites from their teeth and gums.

Shark

Shark cartilage is used to make artificial skin for burn victims.

Leech

People once thought illnesses were caused by too much blood, so doctors used leeches to suck out the “extra” blood.

Dingoes

Dingoes are not wild dogs. They are actually feral dogs, dogs that were once domesticated, but have reverted to living in the wild.

Platypus

The platypus belongs to the order Monotremata the most primitive group of living mammals. The only other member of this group is the echidna and both live exclusively in Australia.
