Male peacock spiders are fuzzy, strangely adorable, and boast a brilliantly colored abdomen that they flip up and use as a prop for an elaborate (for a spider) mating dance.
In this video, the mating dance of the peacock spider has been helpfully set to music, so you can really see why his abdomen makes female spiders wanna shoop.
This particular specimen is apparently a representative of an as-yet-unnamed species of peacock spider. You can read more about this species, and what makes it different from its cousins, in this paper by Jürgen C. Otto and David E. Hill, who also made the video.
