Proboscis bat

The proboscis bat, also known by various names such as the long-nosed proboscis bat, sharp-nosed bat, Brazilian long-nosed bat, and river bat, or murciélago narizón in Spanish, is a distinctive bat species native to South and Central America. It belongs to the Emballonuridae family and is the sole species in its genus.

This small bat measures approximately 6 centimeters in length and weighs about 4 grams. It is notable for its long, fleshy, pointed nose, soft brownish-grey fur accented with white stripes down its back, and gray tufts of fur on its forearms.

The proboscis bat can be found in lowland areas across the northern half of South America, Central America, and southeastern Mexico. They thrive in wetlands, riparian forests, pastures, swamps, and regions near water, typically below 300 meters in elevation. These bats are nocturnal and live in colonies ranging from five to ten individuals, though some groups can grow to as many as forty. During the day, they roost in a distinctive formation, lining up nose-to-tail on branches or beams.

Proboscis bats rely on echolocation to hunt insects near water sources. They do not have a specific breeding season and form stable harems year-round, with each female giving birth to one young. After weaning at 2-4 months, both males and females disperse. Interestingly, these bats can fall prey to the large spider Argiope savignyi.

With their unique features and behaviors, the proboscis bat is a fascinating species, making it a captivating subject for study within the rich ecosystems of South and Central America.
