The animal renowned for its intelligence and exceptional problem-solving skills is the dolphin. These marine mammals are known for their sophisticated social structures, ability to communicate using complex vocalizations, and impressive cognitive abilities. Research has shown that dolphins can learn behaviors, recognize themselves in mirrors (a sign of self-awareness), and work collaboratively to solve challenges or navigate their environment. Their intelligence is further evidenced by their use of tools and their capacity for emotional depth, making them a fascinating subject of study in animal behavior and cognition.
