Giant Yellowleg Centipede
This centipede is the only Scolopendra that can kill a human being. It is also the largest, averaging around 26 cm in length. It feeds on lizards, frogs and birds. Although it rarely attacks humans, its bite may cause sharp pain, severe swelling, chills, fever, and weakness. The venom from this centipede has also been used in the past as a cure for rheumatism, kidney stones, some skin diseases and severe scars. While not a true insect, centipedes are arthropods, which are related.
