Detailed explanation-1: -Elephants are the largest land mammals in the world, so it’s perhaps not surprising that they have the longest pregnancy of any living mammal: African elephants are pregnant for an average of 22 months, whilst for Asian elephants it’s 18 to 22 months.

Detailed explanation-2: -How long an elephant is pregnant for depends a little on the species. African elephants are pregnant for up to 22 months, while Asian elephants are pregnant for 18-22 months. This is actually the longest gestation period of all mammals, which makes sense when we think about how big elephants are.

Detailed explanation-3: -Intelligent, long-lived species often have lengthy pregnancies, which allows ample time for fetal development. The African elephant has the longest pregnancy, at a whopping 22 months.
