As Sonny is famous for having a major dislike for creatures like sharks, spiders and snakes the team jokes with him that the Congo has a huge spider that can jump two feet. The largest jumping spider in the world is actually the Hyllus giganteus (giant jumping spider), it lives in Australia and Indonesia. It is small compared to other types of large spiders like tarantulas, but is large for a jumping spider with a body length of about one inch, they usually are able to jump distances of 8-10 inches.
While there are no known dangerous spiders in the Congo, the Congo water cobra can be found there, they are a rather large snake with an average length of 3.6 feet, but can grow to be over 7.5 feet long. The water cobra possesses a dangerous neurotoxic venom, with a median lethal dose of 0.12 mg/kg it has one of the most potent venoms of the cobra family, by comparison the king cobra's venom has a median lethal dose of 1.644 mg/kg. Water cobras do not inject nearly as much venom as king cobras, and they do not encounter humans nearly as often, so they aren't considered to be as deadly as a king cobra, however there is no specific antivenom for water cobras which can make their bite potentially more dangerous than most other cobras.
