The Yami were the only Formosan aborigines to use armor in combat. This armor for the body armor is beautifully made with rattan and fish skin sewn into coconut bark and wood. Once dried, fish skin can be tough enough to protect against strikes and even an attack from a spear. No other Austronesian people have been known to use fish skin in this unique way. Unlike other Taiwan aborigines groups, the Yami were not head hunters, though they frequently fought amongst each other to settle a dispute or avenge an insult. Family squabbles could quickly involve the community and lead to inter-village fighting.
