Hello,

Me and my friends have been wondering for a while now about following photo. I found this beauty in a narrow passage I had to get through while visiting Machu Picchu in Peru. I had no idea if it was poisonous or dangerous in any way but it looks very ominous.

A friend of mine sais Brazilian wandering spider but in my opinion it looks nothing like that. Does anyone have an idea what spider this is and if it was dangerous or not?
