Madagascan rousette of the genus "Rousettus", these bats reside within cave roosts, suggesting the use of echolocation. These bats are a part of a larger group of fruit bats within "Rousettus" which consists of 10 different species. The Madagascan rousette primarily resides on western Indian Ocean islands. The habitat of the Madagascan rousette is generally found to be associated with forests. They will roost well beyond the time of twilight. Many roosts have been found within caves however some bats have been found without a known cave roost, suggesting that the Madagascan rousette may sometimes roost within tree holes or other alternatives.
Animal echolocation rats can use echolocation to navigate mazes. Echolocation systems are susceptible to interference known as echolocation jamming or sonar jamming. Jamming occurs when non-target sounds interfere with target echoes. Jamming can be purposeful or inadvertent and can be caused by the echolocation system itself, other echolocating animals, prey, or humans. Echolocating animals have evolved to minimize jamming; however, echolocation avoidance behaviors are not always successful. "Galleria mellonella" exhibits predator avoidance behaviors such as dropping, looping, and freezing when emitters sent out ultrasound waves, indicating that "G. mellonella" can both detect and differentiate between ultrasound frequencies used by predators or from
