The evening bat (Nycticeius humeralis) is a species of bat in the vesper bat family that is native to North America. [2] Hunting at night, they eat beetles, moths, and other flying insects. Description
Low-flying bats are vulnerable to crocodiles. [180] Twenty species of tropical New World snakes are known to capture bats, often waiting at the entrances of refuges, such as caves, for bats to fly past. [181] J. Rydell and J. R. Speakman argue that bats evolved nocturnality during the early and middle Eocene period to avoid predators. [179]
A bat wing, which is a highly modified forelimb. Bats are the only mammal capable of true flight. Bats use flight for capturing prey, breeding, avoiding predators, and long-distance migration. Bat wing morphology is often highly specialized to the needs of the species. This image is displaying the anatomical makeup of a specific bat wing.
They are prodigious eaters and can consume up to 2.5 times their own body weight in fruit per night. [97] Megabats fly to roosting and foraging resources. They typically fly straight and relatively fast for bats; some species are slower with greater maneuverability. Species can commute 20–50 km (12–31 mi) in a night.
The term echolocation was coined by 1944 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. [1] [2] As Griffin described in his book, [3] the 18th century Italian scientist Lazzaro Spallanzani had, by means of a series of elaborate experiments, concluded that when bats fly at night, they rely on some sense besides vision, but he did ...

They live in South Asia, Southeast Asia, Australia, East Africa, and some oceanic islands in the Indian and Pacific Oceans. [3]
