14.Papua New GuineaL<strong>and</strong> Area (km 2 ): 462,243Sea Area (EEZ) (thous<strong>and</strong>s of km 2 ): 3,120Papua New Guinea encompasses the eastern half ofthe isl<strong>and</strong> of New Guinea, as well as the BismarckArchipelago, the Trobri<strong>and</strong> Isl<strong>and</strong>s, Samarai Isl<strong>and</strong>,Woodlark Isl<strong>and</strong>, D’Entrecasteaux Isl<strong>and</strong>s, theLouisiade Archipelago, <strong>and</strong> the northernmostSolomon Isl<strong>and</strong>s of Buka <strong>and</strong> Bougainville.Two dedicated marine mammal surveys have beenconducted in Kimbe Bay, West Britain, to investigatediversity within this region (Munday 1994, Visser2003). Munday’s work summarized previous sightings<strong>and</strong> <strong>report</strong>s as well as his own records to produce apreliminary cetacean checklist of sperm whale, shortfinnedpilot whale, orca, false killer whale, melon-headedwhale, bottlenose dolphin, <strong>and</strong> spinner dolphin. Inaddition anecdotal <strong>report</strong>s of humpback <strong>and</strong> pygmy killerwhale were documented. Sightings <strong>and</strong> acoustic datataken by Visser (2003) in a similar region during April2003 confirmed seven species: pygmy sperm whale,Cuvier’s beaked whale, bottlenose dolphin, Indo-Pacificbottlenose dolphin, pantropical spotted dolphin, spinnerdolphin <strong>and</strong> Risso’s dolphin. Preliminary work conductedby Visser identified an additional four species (i.e., melonheaded,false killer whale, short-finned pilot whale, <strong>and</strong>orca). Tentative identifications of Blainville’s beakedwhale <strong>and</strong> rough-toothed dolphin were also made.Bryde’s whales were documented to receive discoverytags around the PNG region (Ohsumi 1978). Largenumbers of both Fraser’s dolphins <strong>and</strong> melon-headeddolphins were sighted between New Guinea <strong>and</strong>Micronesia in the mid 70s (Miyazaki <strong>and</strong> Wada 1978)<strong>and</strong> more recently Fraser’s dolphins have again beensighted (Odyssey web logbook 2001). Irrawaddydolphin may frequent Papua New Guinean waters, asincidental takes in the Gulf of Papua have been noted(Dawbin 1972, Stacey <strong>and</strong> Arnold 1999) <strong>and</strong> this specieslists PNG within its geographic range (UNEP-WCMC2003). Papua New Guinea is also listed as part of thegeographic range of the southern right whale dolphin(UNEP-WCMC 2003), almost certainly erroneously.The presence of the Indo-Pacific humpback dolphin inPapua New Guinean waters is a unique addition to thePacific Isl<strong>and</strong>s cetacean fauna (Dawbin 1972, Jefferson<strong>and</strong> Karczmarski 2001, UNEP-WCMC 2003). However, itspresence has been documented in areas of close proximityto Papua New Guinea rather than directly in the EEZ.15.Pitcairn Isl<strong>and</strong>sL<strong>and</strong> Area (km 2 ): 39Sea Area (EEZ) (thous<strong>and</strong>s of km 2 ): 800The Pitcairn Isl<strong>and</strong> group is a British overseas territoryin the south-central Pacific Ocean <strong>and</strong> includesPitcairn, Henderson, Ducie, <strong>and</strong> Oeno <strong>isl<strong>and</strong>s</strong>.Very few records exist for the four coral <strong>isl<strong>and</strong>s</strong> thatconstitute the Pitcairn group. A relatively recentbiodiversity <strong>report</strong> for this UK territory did not list anymarine mammals for the region (Proctor <strong>and</strong> Fleming1999).
