Interesting. From what I read, A. Seemani was considered "intermediate" due to being skittish, fast and not wanting to be handled. But I didn't really see much of the speed when I moved her into the tank, and no tarantula actively likes being handled so, yeah, kind of weird. And this was a big box store so I wasn't exactly expecting any advanced species to be sold there anyway (but I did do my due research beforehand regardless).
You're the second person to suggest she's female, so I guess it's a safe bet that's what she is by now.
