I've got rhythm, I've got rhythm, I've got rhythm, who could ask for anything more? Possibly a contact microphone used for sound amplification. Great and weird stuff from nature. And this:
Jumping spiders use their legs to communicate courtship interests to potential mates. The miniscule impacts of spider legs tapping against the ground surface are detected by nearby spiders. This "drumming" cadence signals the spider's reproductive interests. The female detects the low frequency vibrations through her legs. She responds by allowing the male to mount her.
