How does the attachment of pangolin scales differ from the armor of armadillos?

Answer

Pangolin scales are not attached to the bone, unlike armadillo osteoderms.

Pangolin scales lack attachment to the bone, which grants them greater flexibility necessary for curling completely into a defensive sphere, unlike the bony plates found in armadillos.
