18. Giraffe
This is a one-of-a-kind image, captured at the absolute perfect moment. This pregnant giraffe has to do a little contortion just to get a drink of water! Giraffes usually use their long necks to reach into the water and slurp it up but when they have a big pregnant belly, things get a little tricky. The gestation period for a giraffe is 13-15 months, and they almost always have one baby.
