Badgers shelter underground. Some are solitary, moving from home to home, while others are known to form clans.

Their lower jaws are articulated to the upper by means of transverse condyles firmly locked into long cavities of the skull, so dislocation of the jaw is all but impossible. This enables the badgers to maintain their hold with the utmost tenacity, but limits jaw movement to hinging open and shut, or sliding from side to side without the twisting movement possible for the jaws of most mammals.
