Meet one of the largest bats in Central and South America: the black mastiff bat (Molossus rufus).

This winged-mammal has a wingspan of up to 22 in (56 cm) and weighs in around 2.5 oz (70 g).

Since this critter doesn’t migrate or hibernate, it spends most of its time roosting. It may even be found in colonies of up to 500 individuals!

The black mastiff bat can travel as much as 250 mi (402 km) in a single night searching for food or water, although it typically stays within 6 mi (9.7 km) of its roost.
