The animal famous for having a long neck is the giraffe. Giraffes are the tallest land animals, with adult males reaching heights of up to 18 feet (5.5 meters). Their long necks, which can measure nearly 6 feet, help them reach leaves and fruits high in trees, primarily acacia species. Moreover, their long necks play a role in intraspecific competition among males, known as "necking," where they use their necks to strike each other in battles for dominance and mating rights. Giraffes are native to Africa and are recognized for their distinctive spotted patterns.
