How much does a Summit rat weight?

It is hard to guess what a Summit rat weights. But we have the answer:

An adult Summit rat (Rattus baluensis) on average weights 107 grams (0.24 lbs).

The Summit rat is from the family Muridae (genus: Rattus). When reaching adult age, they grow up to 19 cm (0′ 8″).

As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.

The average adult weight of a Summit rat is 107 grams (0.24 lbs)

The summit rat (Rattus baluensis) is a species of rodent in the family Muridae. It is found only on Mount Kinabalu and Mount Tambuyukon, Malaysia, and has been recorded at altitudes of between 1,524 and 3,810 m.. The rat populations from these two peaks were connected in the Holocene. However, nowadays they are genetically isolated despite they are only 18 km apart. With current predictions of Global warming, the suitable habitat for Rattus baluensis is expected to shift around 500 m upwards. This will put the population in Mount Tambuyukon at risk. However, the population in Mount Kinabalu will likely survive in its upper slopes.The summit rat has a mutualistic relationship with a species of giant pitcher plant, Nepenthes rajah. Like the treeshrew Tupaia montana, it defecates into the plant’s traps while visiting them to feed on sweet, fruity secretions from glands on the pitcher lids.
