I knew they were not actual spiders, yet I couldn't find their actual name, they just got the name Camel Spider from people. The only reason to fear one is just because its a big stinking spider! They don't attack humans, but what your should truly fear is African ants, they eat more accumulative animal flesh than lion or tigers.
The Siafu ants do not care about your size, they are the only recorded insects that eat humans. Granted they eat infants or the infirm but that is still a very scary thought.
The saifu ants with colonies up to 22 million recorded individuals, use the larger ants with the pincers to break open their victims flesh then the smaller ones get inside and eat it from the inside out.
