Peacock spiders perform their mating dance to a disco beat with the Bee Gees' tune "Staying Alive" from the movie Saturday Night Fever. If this doesn't impress those lady spiders, I don't know what will! They not only dance well, but they display an astonishing variety of colors and patterns on their butts.
Jürgen Otto, also known as Peacockspiderman, dipped into his extensive archives of spider videos and put this awesome music video together. There are 51 different spiders spiders here. -via Tastefully Offensive
