The great fruit-eating bat (Artibeus lituratus) is a bat species found from Mexico to Brazil and Argentina, as well as in Antigua and Barbuda, Barbados, Grenada, Martinique, Saint Lucia, Saint Vincent and the Grenadines and Trinidad and Tobago.
They weigh 10.5 grams (0.37 oz) at birth and grow to 65 grams (2.3 oz) as adults. The heart of A. lituratus contains unique membranous structures not seen in any other mammal. The functions of these differences are still being studied, but may possibly aid in keeping the heart in the correct position while upside down, flight assistance, and energy reservation.
In Panama, it has been found that some Artibeus lituratus fly with 18-23g fruits of Dipteryx panamensis (Fabaceae), which is a third of the animal's body weight, up to hundreds of meters from the parent tree. Reproductive damage within A. lituratus has been linked with the insecticide deltamethrin. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Great Fruit-eating Bat is recorded against all the mammals logged in Rio de Janeiro (6 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.
