A "large animal" typically refers to any animal that is significantly bigger than average-sized animals within its species. This category includes mammals like elephants, giraffes, and whales, as well as birds like ostriches. Large animals often have unique adaptations that help them survive in their environments, such as thick skin for protection or long legs for running. These animals can be found in various habitats, including forests, savannas, and oceans. Their size can influence their role in the ecosystem, as they may be predators, prey, or even keystone species that help maintain the balance of their environment.
