The Lord Howe Stick Insect
These insects grow so large, that they were once known as “tree lobsters.” However even a giant size couldn’t save the tropical bugs from hungry rats, which were introduced by humans in the early 1900s. For almost 50 years, everyone assumed they were extinct, then a handful of survivors remained living under a single bush, clinging to life of a 225-foot-tall rocky outcropping that juts out of the sea. Such troopers.
Chacoan peccary
By size, the Chacoan is the largest species of peccary, which is primarily a beast that resembles a pig but hails from a different continent and cannot be domesticated. They were first described in 1930 based only on fossil records, therefore they were believed to be extinct. Then in 1975, a few rather surprised researchers discovered there was one alive in the Chaco region of Paraguay. Currently, there are around 3,000 known Chacoan peccary.
