It is hard to guess what a Santa Cruz mouse weights. But we have the answer:
An adult Santa Cruz mouse (Peromyscus sejugis) on average weights 21 grams (0.05 lbs).
The Santa Cruz mouse is from the family Muridae (genus: Peromyscus). When reaching adult age, they grow up to 9.8 cm (0′ 4″).
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 Santa Cruz mouse (Peromyscus sejugis) is a species of rodent in the family Cricetidae. It is endemic to Mexico, where it is found only on two small islands in the southern Gulf of California. Feral cats on Santa Cruz Island are a threat.
