The Kanohi Kaukau was the Mask of Water Breathing, sometimes called the Mask of Water. It gave its user the power to breathe underwater, albeit only to a certain depth and for a limited amount of time.
Kaukau were carved out of a mixture of Shrink, Regeneration and Remove Poison Kanoka on Metru Nui.
- Great: Gali, Kopaka, Pohatu, and Onua used their Kanohi Kaukau to retrive a Miru hidden underwater in BIONICLE Chronicles 1: Tale of the Toa.
