Source-derived summary

The Polynesian rat, Pacific rat or little rat (Rattus exulans), or kiore, is the third most widespread species of rat in the world behind the brown rat and black rat. Contrary to its vernacular name, the Polynesian rat originated in Southeast Asia, and like its relatives has become widespread, migrating to most of Polynesia, including New Zealand, Easter Island, and Hawaii. It shares high adaptability with other rat species extending to many environments, from grasslands to forests. It is also closely associated with humans, who provide easy access to food. It has become a major pest in most areas of its distribution.

Description

The Polynesian rat is similar in appearance to other rats, such as the black rat and the brown rat. It has large, round ears, a pointed snout, black/brown hair with a lighter belly, and comparatively small feet. It has a thin, long body, reaching up to 15 cm (5.9 in) in length from the nose to the base of the tail, making it slightly smaller than other human-associated rats. Where it exists on smaller islands, it tends to be smaller still – 11.5 cm (4.5 in). It is commonly distinguished by a dark upper edge of the hind foot near the ankle; the rest of its foot is pale.

Editorial summary

Begin with the source’s own compact description: “Polynesian rat” is species of mammal. The dossier treats that line as a proposition to test through Polynesian, species and mammal, not as a finished interpretation.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 212-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Polynesian, species and mammal is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of mammal” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q339418. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.

Three-step research path

  1. Establish the record: confirm the title “Polynesian rat”, its source revision and the description used here.
  2. Expand the search: follow Polynesian rat primary sources, Polynesian rat archive and Polynesian research across catalogues and specialist indexes.
  3. Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.

Questions for further research

  1. Which source most directly establishes the central claim about “Polynesian rat”?
  2. Has classification or technical consensus changed since the cited source?
  3. Is the terminology current, historical or disputed?
