It is hard to guess what a Cozumel harvest mouse weights. But we have the answer:
An adult Cozumel harvest mouse (Reithrodontomys spectabilis) on average weights 20 grams (0.04 lbs).
The Cozumel harvest mouse is from the family Muridae (genus: Reithrodontomys). When reaching adult age, they grow up to 8.7 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 Cozumel harvest mouse (Reithrodontomys spectabilis) is a species of rodent in the family Cricetidae. It is endemic to the Mexican island of Cozumel off the Yucatán Peninsula. It is nocturnal and semiareboreal, and lives in dense secondary forest and forest edge habitats. Its population is small, fluctuating and patchily distributed. The species is threatened by predation from feral cats and dogs and introduced boa constrictors, by competition with introduced nonnative rats and mice, and by habitat disturbances caused by hurricanes and floods which periodically strike the island.
