Pedes bite and some are highly poisonous. I hold some of my tarantula's (the one's that tolerate it-some will bite and some will kick hairs) if I need to move them or something but I don't really hold them to just hold them though. I am like that with all my animals though. Most of the really poisonous tarantula's are old world but I don't keep any of them.
The male tarantula's sadly only live a few years (long enough to mature and do their thing) but the females will live a long time. And no problems about asking all the questions!!! I love answering them
