Found this as part of an interesting blog post about social behaviour in spiders. It's one of Otto Jurgen's videos about Peacock Spiders, although this species is more cryptic than most. It also has dance-offs against rival males :)
They're especially adorable waking up from their little sleeping bags in the morning :)
