An illustration of a pichiciago, a small burrowing armadillo. The front half of the animal is covered in the endoskeleton. The back half of the animal is stripped of the outer skeleton so that the exoskeleton or dermoskeleton can be viewed. The scientific name of the pichiciago is <i>Chlamydophorus truncatus</i>.

"A joint involving the principle of the shackle. Specifically, in anatomy, a kind of articulation found in the exoskeleton of some fishes, formed by the passing of a bony ring of one part through a perforation of another part, the two being thus movably linked together." &mdash;Whitney, 1889 <p>This illustration shows the shackle joint of a large spine with a bony plate of the skin of a siluroid fish.
