Giant stick insects

The longest insects on the planet are stick insects, which have evolved a bizarre shape to hide themselves from predators among branches, twigs and foliage.

The giant walking stick from Southeast Asia is the longest variety, growing to as long as about 2 feet in length. Some species can produce a pungent-smelling defensive spray, but these bugs are mostly harmless and are often kept as pets.
