Wild fish can recognize individual divers

Wild fish have the ability to recognize individual divers using visual cues, such as different wetsuit colors. A study found that fish could learn to identify divers based on their appearance, especially when rewards, like food, were involved. In experiments, fish began to follow a diver wearing a specific colored vest and were able to differentiate between her and another diver when they wore different gear. This behavior showed that fish actively learned to associate specific visual traits with their experiences, supporting the idea that they can recognize humans in the ocean.
