The pink fairy armadillo (Chlamyphorus truncatus) or pichiciego is the smallest species of armadillo (mammals of the family Dasypodidae, recognized by a bony armor shell), first described by R. Harlan in 1825. This desert-adapted animal is endemic to central Argentina and can be found inhabiting sandy plains, dunes, and scrubby grasslands.
Pink fairy armadillos have small eyes, silky yellowish white fur, and a flexible dorsal shell that is solely attached to its body by a thin dorsal membrane. In addition, its spatula-shaped tail protrudes from a vertical plate at the blunt rear of its shell. This creature exhibits nocturnal and solitary habits and has a diet that is mainly composed of insects, worms, snails, and various plant parts.
