I am not afraid of any reptiles, however I do have a healthy respect for those that can inflict serious injury if you do not respect them.
They aren't reptiles, but I do have a silly irrational fear of many spiders... Daddy Long Legs take the cake. I like the little white spiders, and in fact had a whole bunch of them living in my car one summer. Jumping spiders are cute o> Most tarantulas are gorgeous IMO, however they give me a serious case of the heebie jeebies, some more than others. I would really like one as a pet, but I'm not sure how feasible that is...
