Another interesting bit about Ball's Pyramid: "In 2001, a team of entomologists and conservationists landed on Ball's Pyramid to chart its flora and fauna. As they had hoped, they discovered a population of the Lord Howe Island stick insect," commonly referred to as the rarest insect on earth:

The population was extremely small, only 24 individuals. Two pairs were brought to two Pacific zoos to breed new populations. On the unsuccessful 1964 climb, Dave Roots brought back a photograph of the insect, which the Australian Museum told him they thought was extinct.
