Fish communicate underwater using various methods such as vocalizations, visual signals, body language, and chemical signals. Some fish species produce sounds by vibrating their swim bladders or grinding their teeth together. They also use body movements and color changes to convey messages to other fish. Additionally, some fish release chemical signals, known as pheromones, into the water to communicate with nearby individuals. These diverse communication methods help fish interact with each other, establish territories, attract mates, and warn about potential danger.
