Golden orb spiders aren't dangerous to humans as far as I know. They're definitely beautiful though, especially with webs so strong they can catch birds.
Lala, they feel vibrations most strongly through their bottom jaws. Some suggest they can "hear" sounds through vibrations in the air as well, since there's evidence they have inner ears, but they don't have an opening to be able to hear sounds, so to speak. I can't find any definitive research on the matter, but an interesting theory nonetheless.
