Next on our list of weirdest animals is the pink fairy armadillo. The pink fairy armadillo is the smallest species of armadillo. You can only find them in central Argentina. They have a carapace like the other armadillo species. However, it is softer, thinner, and more flexible. The pink armadillo has a pink shell because all its blood vessels are close to its surface. 

It grows up to 6 inches long. Pink Armadillos can also control their temperature by pumping blood to their thin shells. This action removes the heat from their bodies and replaces it with coolness. Observing pink fairy armadillos in the wild is difficult because they usually hide themselves. You might only see glimpses of them if heavy rainfall evicts them from their earthly homes.
