Cellar Spider
Don't get too scared!
You ever go near that dark corner in your basement and see a web and hope nothing's in it? Well even if there is something there, it's probably just a cellar spider, often called a "daddy longlegs". These guys don't hurt you, but instead just find the darkest and furthest corner to try and catch any unprepared smaller bugs that they can make their next easy meal.
Tarantula
Another creature from the deep is the tarantula, and although some people might find them cool (like me), these venomous spiders are still pretty scary to see up close. Imagine a fuzzy spider as big as your hand, and on top of being huge, their venom can cause a serious reaction if it bites you. Maybe not enough to kill you, but certainly enough to warrant a trip to the hospital just in case. On second thought, maybe I'll keep my distance from these guys, last thing I need is to get antivenom because a spider with several inch long legs bit me. These things also sound kinda creepy too, take a listen!
