2. Turtle


Although turtles don’t carry live young during their version of pregnancy, they do develop and carry around eggs. This x-ray image shows the location of the eggs in a turtle, where they will remain until momma digs the perfect whole for her nest. The gestation period depends on the type of turtle, but scientists say it ranges from seven weeks to two years. Two years is a long, long time to carry around some babies. The eggs then incubate for around 60 days.
