The giant stick insects (a family of tree lobsters) that lived more than ninety years ago on Lord Howe Island were thought to be extinct. Scientists assumed that the rats brought to the island, which ate these twelve centimeter insects, were to blame for this event. But, as it turned out, this species has survived, only in a completely different place.
Climbers were the first to report huge six-legged insects that secretly tried to climb to the top of the world's tallest rock, the Ball Pyramid. This rock stands apart from everyone else in the ocean. It is located twenty kilometers from Lord Howe Island and is closed to visitors. Its height is five hundred and sixty-two meters.
A pair of Australian biologists Nicholas Carline and David Priddell decided to check this information. They went on a scientific expedition to the rock and soon found those very giant stick insects. Four of them were brought to Australia to study and reproduce in detail. Two individuals did not make it to their destination, but those who remained easily took root and multiplied.
