A 12-centimeter-long stick insect that hadn’t been seen for 80 years was rediscovered in 2001. Only 24 individuals remained, so conservation became vitally important.
Today, there are over 9,000 of the stick insects, thanks to the conservation efforts at the Melbourne Zoo. However, they are still considered critically endangered by the IUCN.
