When the humans and animals made the agreement that they would eat and hunt each other, the ocean goddess did not expect the animals of the sea to be included in the agreement. However, she began to notice humans and animals started eating fish and making them into food. She even saw some of her precious dolphins become food when people hunted them with spears. The Lady of The Waves did not appreciate her creations being hunted, so she made some animals that were not friendly and some that were scary and would discourage humanity from bothering the innocent fish. She created stingrays, piranhas, and sharks. Even though humans were not their main source of food, they were still scary enough to persuade humanity to stay away from them.
