X-RAY VISION

摘要

Bees see the world in a very different way to humans. They have five eyes that cover much of their heads, and each eye has a region that is sensitive to polarised light. The light of the sky is polarised relative to the position of the sun, and bees use this information to navigate. We now know that some rainforest-dwelling bees possess the tools necessary for complete polarisation analysis: accurate measurement ot both the angle and extent of polarisation.
