A bee tells her whole hive exactly where the flowers are by dancing a figure eight

Karl von Frisch discovered that returning worker bees perform a 'waggle dance' whose angle points toward a food source relative to the sun, while how long the dance runs encodes the distance. Decoding this dance language earned him a share of the 1973 Nobel Prize in Physiology or Medicine.
