I'm new to this forum, and never been to Africa yet. I do like to hunt and fish, out in CA, hunting is more like gleaning. However I have read a fair amount and some of it was about the creepy crawlies.

Africa has very large tarantulas (ground spiders), called Baboon or Imperial Baboon Spiders (they are approximately 8" across) who are very aggressive. They probably live in Savanah, jungle, and/or desert areas.

Another critter in the desert is the camel spider (not really a spider) that moves very fast and has been known to chew up people when they sleep. I read one article about someone who had 1/2 their nose eaten off when they were sleeping. http://www.snopes.com/photos/bugs/camelspider.asp#photo

You all know about scorpions, but the centipedes are also really nasty and have a noxious poision that can swell your leg or arm like a sausage with it's bite. They get to be around a foot long, and are very aggressive. I saw several similar centipedes in the Carribean, the West Indians got very animated and usually scattered when they saw these critters (not as dangerous as a Cape Buffalo, but they were bright red, and the sight of that nasty critter unnerved them).
