Dolphins have long played a role in human culture. Dolphins are common in Greek mythology, and many coins from ancient Greece have been found which feature a man, a boy or a deity riding on the back of a dolphin. Four countries – Chile, Costa Rica, Hungary, and India – have declared dolphins to be « non-human persons » and have banned the capture and import of live dolphins for entertainment. Of the five freshwater species of dolphins in the world, the pink Amazon River dolphin, Inia geoffrensis, or « bufeo colorado” as they are known in Peru and “botos » as they known in in Brazil, are considered to be the most intelligent. Dolphins appear to have a darker side, according to scientists who suggest they can resort to rape to assert authority. So here is the revenge, spreading on street walls.
