What does the trianle or pyramid mean in a hawaiian tattoo?

Answer 1

NIHO-MANO TATTOO - The niho mano is a pattern of triangles used in traditional Hawaiian tattooing. Sometimes arranged in a row, in opposing rows, or stacked in a pyramid, the niho mano is very likely a representation of shark teeth.

In Hawaii, the art of tattoo was called kaka u i ka uh i, or to "strike on the black." As in other parts of Polynesia, tattooed designs enveloped the body with genealogical and spiritual power, and transformed living bodies into dwelling places for the gods and protective ancestors called 'au-makua.
