19. Zebra
The expressions on these animals keep getting better and better, and this zebra takes the cake. Not only does this photo show just how wide a zebra gets while pregnant, but her expression shows us just how it feels too. Pregnancy for a zebra isn’t as great as it is for some animals on this list because it’s actually a rather dangerous time; they are very vulnerable during both the pregnancy and birth. The pregnancy lasts up to 12 months and usually results in one baby.
