Aw. Spides are actually shy creatures. They are just as, if not more, afraid of us as we are of them. Did you know that tarantulas can shed? They can shed if they're anxious. So if a tarantula gets handled enough by strangers, pretty soon it can end up being a scared and bald tarantula.
They're also venomous and generally creepy. A large enough portion of people are arachnophobic, like me.
And I thank God for those tarantula wasps.. You know, those wasps that attack tarantulas and lay their eggs in them, for their baby waspies to eat the host spider. biggrin
