The African elephant holds the title for the longest gestation period among animals, lasting approximately 22 months. This extended pregnancy period allows the developing fetus to grow to a size that will enable it to thrive in the wild after birth. The long gestation is essential for the calf's physical development and ensures a better chance of survival in the harsh habitats where elephants reside. Typically, calves are born weighing around 200 pounds and are able to stand and walk shortly after birth, quickly integrating into the herd under the guidance of their mothers and other family members.
