Dolphins
Dolphins are known to use tools for hunting; the marine mammals will chase fish into shells that they then bring to the surface, shaking the piscine prey out of their hidey holes. But researchers in the Red Sea recently discovered another way dolphins use their environment to their advantage. In May, a team of scientists published a paper describing how dolphins in the sea will rub their bodies against specific coral species, in what seems to be an act of self-medication. The process is called (brace yourself) zoopharmacognosy, and the scientists believe the dolphins were trying to get the coral to release mucus, which has antibacterial properties.
