In terms of appearance, Dayak's are recognized by two distinct features: one the females have their ears peirced young and get heavy earrings placed on the lobes which cause them to stretch. The second feature is that they get their teeth filed into jagged edges. The reasoning for this is to help better eat meat. Neither the explanation for wearing heavy earrings isn't complicated. It is said that the first dayak who lived in the forest, long time ago, had a unique way to distinguish humans and monkeys, "If has the short ears mean he’s a monkey…" So according to Dayak Kenyah people, ears lobes elongation is used as a marker of their human identity. In line with this, the Ministry of Education and Culture confirmed for the Kenyah and Bahau, people who don't ear length is considered similar to an ape.
