The spiderweb is tuned to particular frequencies, indicating a selective response to vibrations rather than any vibration.

“Not just any vibration, right? You know, there's the idea that there's any vibration, I know I've got, you know, food somewhere, I should go to that food source, but instead it's something that if I experience a threat or something, I'm going to behave. And that is a more selective, you know, response that I've tuned it towards.”
