Dina, a young dolphin, had always been curious about the ocean's secrets. One morning, she noticed that her pod had disappeared without a trace. However, she remembered her mother's words: "Actions speak louder than words." Therefore, she decided to search for them instead of just waiting. She knew that dolphins, like all mammals, must breathe air through their blowholes, so she surfaced often to scan the horizon.
As she swam, Dina used echolocation to navigate the dark waters. She clicked and listened for the echoes that would reveal her surroundings. Suddenly, she heard a distant song—it was the call of a humpback whale. The whale explained that he had seen a dolphin pod heading north on a migration route. "If you follow the current, you might catch up," he said. Dina thanked him and quickly swam away.
