Hippo sweat to be turned into sunscreen. Key part is this:
After analyzing the hippo sweat under a microscope, the researcher found that there were two types of crystaline structures in it – banded and non-banded. He pinpointed that the banded ones were “characterized by concentric dark rings,” which seemed to be the key to the liquid’s amazing properties. “The rings are the result of a structural periodicity that occurs on a scale comparable to the wavelengths of visible light. This means that the sweat is an effective scatterer of light, so that it combines both sun-blocking and sun-screening properties,” Viney stated.
So basically they are saying that hippo sweat is, like, a cloaking device. Which means that hippopotami could be Predators if they ever bothered to get out of the damn river. We are extremely lucky that hippos are lazy.
