Tool use is often considered a sign of intelligence, and many animals have mastered it. Chimpanzees use sticks to extract termites from mounds, while crows craft tools from leaves and twigs to access food. Dolphins even use sponges to protect their snouts while foraging on the ocean floor.
Elephants, sea otters, and octopuses are also known for their innovative problem-solving skills. These animals demonstrate that intelligence and creativity exist throughout the animal kingdom.
