6. Orangutan
This orangutan’s face is quite funny; it’s like she’s pondering what’s to come and can’t wait to get back in shape. Although, let’s get real, orangutans usually look pregnant because they always have giant bellies. The gestation period is around 274 days and they only give birth every seven to nine years, so when they do it’s rather special. They take special care of each one and continue to nurse them for 5 years.
