The thylacine is commonly known as the Tasmanian tiger (as it had stripes on its back) or the Tasmanian wolf (as it resembled a small wolf or a dog). The name "thylacine" comes from Greek, meaning dog-headed pouched one. The Tasmanian tiger was the largest carnivorous marsupial of modern times, until it went extinct in the 20th century. The thylacine was the only remaining member of the Thylacinidae family.

The thylacine is described as a shy nocturnal animal, resembling a medium-sized or large-sized dog with a stiff tail and abdominal pouch.

Intensive hunting, dogs, and human civilization led to the extinction of the species. The last thylacine, named Benjamin, died in captivity inside the Beaumaris Zoo in Tasmania. The Tasmanian tiger was officially listed as a protected animal only 59 days before Benjamin's death.
