A GIANT CENTIPEDE? Are there giant, killer centipedes lurking in the rain forests of South America? As a matter of fact, yes, there are. Scolopendra gigantea, also known as the Amazonian giant centipede or Peruvian giant yellow-leg centipede, is the world's largest living centipede, regularly reaching lengths of 10 to 12 inches, with one reported specimen in Venezuela measuring 18 inches in length. This 46-legged monster feeds on frogs, tarantulas, birds, lizards, rodents and even bats, catching them mid-flight as the centipede hangs from a cave ceiling. Scolopendra gigantea is a very swift runner and highly adept climber. Like all centipedes, it has modified claws that curve around its head and deliver venom to its prey.
