The world of fish hides a fascinating communication system which, although unnoticed by the human eye, organizes life underwater. Contrary to what many imagine, these animals don't rely solely on instincts or automatisms, but rather develop complex silent languages ​​that facilitate their coexistence and survival.
La Communication in fish has been the subject of multiple scientific studies in recent years, because their signals are as sophisticated as they are varied. Although most species lack vocal organs like terrestrial mammals, they have evolved various ways of exchanging information through gestures, colors, movements, the emission of chemical substances, and even water vibrations.
Visual and chromatic signals: the code of colors and movements
One of the most common forms of communication is through changes in the color or patterns of your skin, especially during the breeding season or when they feel threatened. Some species modify their color to show readiness to mate, warn of imminent danger, or claim territory from other individuals. In addition, body movements, such as flapping wings, shaking, or small dances, form a body language which is unmistakable to members of his group.
Communicating through vibrations and subtle sounds
Contrary to popular belief, fish can also generate vibrations in the water or small tapping sounds with different parts of their body or through their swim bladders, creating a kind of "conversation" intended both to attract the attention of potential mates and to warn off rivals. These acoustic signals, almost imperceptible to humans, are used in everyday life underwater and can be key during mating rituals or territorial confrontations.
Chemical secretions and recognition of individuals in the bank
La chemical communication It's another essential mechanism in the aquatic world. Many fish release substances into the water that can change the behavior of other individuals, such as pheromones to attract mates or territorial markers that warn of the presence of a dominant conspecific. This system facilitates recognition among members of the same species and strengthens cohesion within schools, which is essential for protecting against predators and coordinating collective movements.
Recent research and findings on fish communication
In the last times, Scientists have documented new patterns of communication between fish in natural, controlled environments, observing unexpected behaviors in stressful situations or during courtship. These findings are allowing the development of new hypotheses about social codes on the seabed and in lakes, as well as aiding in the conservation of species whose populations depend on the social balance in their ecosystems.
Studying Fish communication is revolutionizing marine biology By opening doors to understanding behaviors that, until recently, were interpreted as mere automatic impulses. We now know that underwater life employs sophisticated interaction strategies that ensure the continuity and adaptation of hundreds of species in the changing aquatic universe.
