Abstract
  • We investigated the species identity and local use of cetaceans on the Gilbert Islands, Republic of Kiribati. Working with the Kiribati Ministry of Environment, Lands and Agricultural Development and Fisheries Division, we visited the islands of Tarawa, Tabiteuea (North), Butaritari and Onotoa from June to July 2009, and collected 24 bones, bone fragments or teeth attributed to recent strandings. The mitochondrial DNA control region or cytochrome b was successfully amplified from 12 bones or bone fragments and used to identify four species: Mesoplodon sp. representing a new species or subspecies of beaked whale, the dense-beaked whale Mesoplodon densirostris, Cuvier’s beaked whale Ziphius cavirostris and the pygmy sperm whale Kogia breviceps. This is the first confirmed identification of the dense-beaked, Cuvier’s and pygmy sperm whales from the Gilbert Islands. All specimens were reportedly used for human consumption.
