After reading the recent IMHO thread on Huntsman spiders, OneCentStamp commented:
Which reminded me of a video I had just seen.
A male jumping spider is jumping, tapping and flexing to attract the attention of a female (who doesn’t respond much). Early on, very faint sounds can be heard, but they get louder until they sound almost like a motorcycle revving by the end.
Now, my work computer doesn’t have much of a sound card so it’s impossible to tell for sure from here. Can anyone confirm whether the sounds with this video are actually coming from the spider? And if so, how? Tapping? Rubbing? Actual vocal cords?
Great, now I’ve got creepy-crawly sensations going over the back of my neck.
