This is my first attempt at posting something on a forum, I have no idea if you can actually view the video, but I really tried!
Anyway, I'm really new to tarantulas and am curious why the spider is "wagging" its abdomen back and forth after it catches the cricket. I see her doing this weird movement all the time, typically if I disturb her in some way (open her enclosure, etc.) she moves her abdomen back and forth and moves her spinnerettes around. Is this some normal behavior that I just don't understand?
