Fisherman, for example, have their own rules when it comes to the boto. Because they are such skilled swimmers, botos have been known to steal fish, leaving behind gapping holes in their nets. But fisherman have a great deal of respect for the creature and regard it as a sacred animal. If a boto is accidentally caught in the net of fisherman, he will do everything in his power to release it or else be cursed forever more. If he is unsuccessful in his rescue, then the boto is a gift from the gods.
Women also have their own standards set by the boto.
They are not allowed to travel on the river during their menstrual cycle for fear the boto may flip their canoe over and put them in danger. In the book, Amazon Emotions, the author shares a story told by a clairvoyant who explained botos come from Sirius, the brightest star in the sky, situated in the Constellation Canis Major. As far fetched as some of these stories may sound. The people of the Amazon region believe in the powers of the boto.
