The gray short-tailed opossum (Monodelphis domestica) is a small South American member of the family Didelphidae.

It was the first marsupial to have its genome sequenced. The gray short-tailed opossum is used as a research model in science, and is also frequently found in the exotic pet trade. It is also known as the Brazilian opossum, rainforest opossum and in a research setting the laboratory opossum.
Gray short-tailed opossums are relatively small animals, with a superficial resemblance to voles. In the wild they have head-body length of 12 to 18 cm (4.7 to 7.1 in) and weigh 58 to 95 grams (2.0 to 3.4 oz); males are larger than females. However, individuals kept in captivity are typically much larger, with males weighing up to 150 grams (5.3 oz). As the common name implies, the tail is proportionately shorter than in some other opossum species, ranging... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Gray Short-tailed Opossum is recorded against all the mammals logged in João Pessoa (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
