Visual markers

- Relatively small ears that do not reach the eye when gently pressed forward on a specimen.
- The stockier build and short thick tail help separate it from the more slender ship rat.

Where
Not established in this record.
Identification notes
- Ship rat: A ship rat is more slender, with larger ears and a tail longer than its head-and-body length. Compare dossier.
- Kiore: Kiore are smaller and more delicately built; uncertain specimens require measurement or expert examination. Compare dossier.
Keep in mind: Perspective can obscure tail-to-body proportion. Do not rely on coat colour alone.
