Senses play an important part in fish communication. Visual communication is important to most fish. Body movements, postures, colors and color patterns are the primary means of visual communication. Sound is also used for communication. Sounds are produced by grinding teeth, flexing or contracting muscles and vibrating the swim bladder. Fish also communicate by releasing chemicals called PHEROMONES. These are chemical signals produced by an animal that, when released, influence the behavior of others of the same species. The sense of smell is important for this form of communication. But fish do not have a language so Finding Nemo can be misleading.
