Which Animal Has the Longest Gestation Period?

Answer – The land animal that has the longest gestation period is the African bush elephant (Loxodonta africana).

Explanation: 

The gestation period is remarkably long, lasting about 22 months, which is nearly two years. During this time, the female elephant carries and nourishes the developing fetus in her womb, which results in a relatively large and well-developed calf.
