Avian Serpentes, or Kailos, dwell in the caves of the Amazon Rainforest. Kailos are poisonous and aggressive creatures. The species is unique and does not have any DNA in common with other animals.

With a snakelike body, Kailos slither to catch prey off the forest floor. On windy days these carnivores spread a pair of feathered wings and can be seen gliding over the trees.

According to Dr. Mafesto, a tenured professor at Vultar University, adult Avian Serpentes weigh 230 kg, reach up to 22 meters in length, and have a 40 meter wingspan. He goes on to say, “Kailos are masters of camouflage, they have evolved a sophisticated layer of scales which can make them invisible to the human eye. The scales help the Kailo hunt without being noticed.”

Laura Fishborne has been the president of the Kailo breeding progam at San Angeles Zoo for over a decade. She states Kailos only breed on February 29 in dark caves. “Before the breeding starts they get very violent. The females often attack the males to see which male is the strongest. After mating, female Kailos care for the young alone.” Fishborne explains.

Kailos are known for their aggressive behavior towards humans. The Protection of Invisible Dangerous Animals Agency, or PIDAA, handles an average of 1000 Kailo attacks on humans annually. According to PIDDA’s website, the cause of Kailo-Human attacks is the scent people emit when sweating. When exposed to the scent Kailos become violent and attack the closest moving object.
