Fishy business

The video explores how fish use polarized light to camouflage themselves in the ocean. Researchers at UT Austin discovered that certain fish can manipulate polarized light to hide from predators. This ability is due to microscopic structures in their skin that scatter light differently. The research has potential applications for the US Navy in developing ocean camouflage. The video concludes with a humorous exchange about a fish story and a debt.
