Animals come in such different shapes and sizes, some of which will make you redefine how you think things works. We live in a world where you can see enormous rabbits and tiny horses. Whether they or astonishingly big or small, some of these animals will make you want to get your eyes checked.

Bright Side brings you some of the most astonishing animals whose size just has to be seen to be believed.

1. There are so many wonders from under the sea, like this giant Leatherback sea turtle.

2. This Flemish Giant rabbit can certainly play with the big dogs.

5. We’re heading to Wonderland!

6. “It’s a bear! It’s a mammoth! No, it’s a giant dog!”

14. This tiny lizard is actually a dwarf crocodile.

Bonus: Sometimes it’s hard to tell if the pony is small or if the dog is just that big.
