Piercing ears was also very common. The Aleuts pierced holes around the rim of their ears with dentalium shells (tooth shells or tusk shells), bone, feathers, dried bird wings or skulls and/or amber. Materials associated with birds were important, as birds were considered to defend animals in the spirit world. A male would wear sea lion whiskers in his ears as a trophy of his expertise as a hunter. Worn for decorative reasons, and sometimes to signify social standing, reputation, and the age of the wearer, Aleuts would pierce their lower lips with walrus ivory and wear beads or bones. The individual with the most piercings held the highest respect.
