This is a tooth of the sperm whale (Physeter macrocephalus), which is usually attached to a cord of coconut fibre rope. Tabua are used as presentation gifts at weddings, funeral and other important occasions. Acquired by chiefs from European traders in the early 19th century, they became highly important in strategic and dynastic exchanges. Such activities increased the chief’s power and influence. Tabua also acted as shrines and ivory items were normally crafted by Tongan or Samoan craftsmen working under the service of Fijian chiefs.
