Some creepy-looking and yet amazing new species have been found in the Greater Mekong River area in Southeast Asia! Among the most eerie creatures among the 1,068 finds are a pink millipede that can shoot cyanide, and what is probably the world’s largest spider–it boasts a legspan of up to 12 inches (30 centimeters). Check out pictures of these spectacular creatures on National Geographic News.
