澳洲袋鼠島特有的刺客蜘蛛（Zephyrarchaea austini）本以為只棲息於西部的一個保護區內，而該保護區在兩年前的叢林大火中被完全摧毀。 刺客蜘蛛本來被認為已經滅絕，但近月研究人員在距離牠們先前已知的棲息地約 4 公里的未燒毀區域，發現了兩隻。 科學家估計現時已認知的澳洲無脊椎物種只有 1/3 ，另外 2/3 可能在人類認識牠們之前就已經滅絕。
The endemic Kangaroo Island assassin spider (Zephyrarchaea austini) was known to live in a protected area in the west of Kangaroo Island, which was completely destroyed by the massive bushfire two yeas ago. It was believed to be extinct but recently, researchers found two of them in an unburnt areas about 4km away from their previously known habitat. scientists estimated only 1/3 of the invertebrate species was discovered in Australia, the other 2/3 might gone extinct before human gets to know them.
