How do animals primarily use visual signals in communication?

Animals primarily use visual signals in communication through body language, coloration, and physical displays. This method of communication is crucial across many species and can convey a wide range of information, including intentions, emotions, and social status. For instance, changes in body posture can indicate aggression or submission, bright colors can signal warning or attract mates, and specific movements or displays can be used to establish territory or attract partners during mating rituals. This form of communication is particularly important in environments where vocalizations might not be effective, such as in densely vegetated areas or underwater, allowing for clear and immediate visual cues between individuals. Understanding these visual signals is essential for interpreting animal behavior and interactions within their social structures.
