Ariamnes flagellum, which is found in India, Southeast Asia and Australia and is about the size of a U.S. quarter, is one of the weirdest-looking creatures you'll ever see -- that is, if you aren't fooled by its ingenious camouflage.
The twig spider has a bright-green abdomen and lines up its tiny, thin legs in a straight line, so that it looks like the tendril of a climbing plant. The only time its presence is obvious is when it moves. Rather that spinning a typical spider's web, this crafty creature opts for single-strand in the shape of Y. But when an unwary flying insect lands on what it thinks is a safe perch, a nasty surprise is in store [source: LifeDesks].
