It is hard to guess what a Japanese water shrew weights. But we have the answer:
An adult Japanese water shrew (Chimarrogale platycephalus) on average weights 36 grams (0.08 lbs).
The Japanese water shrew is from the family Soricidae (genus: Chimarrogale). When reaching adult age, they grow up to 11.6 cm (0′ 5″).
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 Japanese water shrew (Chimarrogale platycephalus), also called the flat-headed water shrew, is a species of mammal in the family Soricidae. It is endemic to Japan.
