Pink Fairy Armadillo

Pink Fairy Armadillo-Chlamyphorus truncatus

You could live your whole life in Argentina and never see a pink fairy armadillo.  
These subterranean nocturnal sand babies only surface at night or when their tunnels are threatened by rain.  Although small enough to fit in the palm of your hand, they are a terror of the Argentinian desert.

Their distinctive pink coloration comes from a large membrane of blood that runs along the inside of their thin shell.  The theory is that having all that blood near the surface allows for easier heat regulation in their desert home.
In an animated film about desert ants, they would play the part of the stygian nightmare, the Nosferatu.  Placing their lairs next to an ant mound, food is readily in claw’s reach.

When it’s time to move on, the dillo’s massive forearms allow them to plow effortlessly through soil and sand, Tremor-style.
