Dingoes never reached Tasmania, and most scientists see this as the main reason for the thylacine's survival there.

However, there seems to have been little public pressure to preserve the thylacine, nor was much concern expressed by scientists at the decline of this species in the decades that followed.

考虑到我们现也知道它与您可能听说过的任何掠食性澳利亚有袋动物（例如塔斯马尼亚袋獾或现已灭绝的袋狼）都没有真正的关系，这一点更令人印象深刻。
