The Lord Howe Island Stick Insects (Dryococelus australis) were thought to be extinct for the past 80 years. Scientists blame their dissappearance on black rats.
Two dead inscts were found but results finally came from constant expeditions and the insects were resently found in 2003 alive on Ball's Pyramid by climbers at night.
Even though at least 30 of the insects were found they still remain on the critically endangered species list.
As of 2008 there were 450 of the Lord Howe Island Stick Insects and slowly coming off of the endangered species list.
