The thylacine was shy and secretive and always avoided contact with humans. Despite its common name, 'tiger' it had a quiet, nervous temperament compared to its little cousin, the Tasmanian devil.

When hunting, the thylacine relied on a good sense of smell, and stamina. It was said to pursue its prey relentlessly, until the prey was exhausted. The thylacine was rarely seen to move fast, but when it did it appeared awkward. It trotted stiffly, and when pursued, broke into a kind of shambling canter.
