Fish are often not given the credit they deserve for their intelligence. However, recent studies have shown that fish are not only capable of complex behaviors, but they also have excellent problem-solving and cognitive abilities. Here are five incredible facts about the intelligence of fish.
Fish Can Recognize Faces
Studies have shown that some species of fish, such as the archerfish and the cleaner wrasse, have the ability to recognize individual faces. The archerfish, for example, can recognize human faces and will spit water at the faces of people they have seen before. This ability to recognize faces is remarkable and shows that fish have a greater understanding of their environment than previously thought.
Fish Communicate with Each Other
Fish have complex communication systems that allow them to communicate with each other. They use a variety of signals, such as visual cues, body language, and sound, to convey messages. Some species of fish even use specialized organs to produce sounds that can be heard over long distances.
Fish Can Solve Problems
Fish are capable of solving complex problems, such as navigating through mazes and using tools to obtain food. In one study, researchers found that octopuses could learn to unscrew a jar to obtain food. This ability to solve problems shows that fish have a high level of cognitive ability and are capable of adapting to their environment.
Fish Have Long-Term Memories
Fish have long-term memories and are capable of remembering things for extended periods. For example, some species of fish, such as carp, can remember the location of food sources for up to a year. This ability to remember and recall information is remarkable and shows that fish are capable of complex thought processes.
Fish Can Use Tools
Several species of fish have been observed using tools to obtain food. For example, some species of wrasse use rocks to crack open shells to access the meat inside. This ability to use tools requires a high level of cognitive ability and shows that fish are capable of complex behaviors.
