from "Animal echolocation"

With echolocation, the bat or other animal can see not only where it is going but also how big another animal is, what kind of animal it is, and other features.

Their use of echolocation allows them to occupy a niche where there are often many insects (that come out at night since there are fewer predators then), less competition for food, and fewer species that may prey on the bats themselves.

During approach to a detected target, the duration of the sounds is gradually decreased, as is the energy of the sound.

This specialization is evident from the inner ear up to the highest levels of information processing in the auditory cortex.

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 other members of their species. Members of the Saturniidae moth family, which include giant silk moths, have been observed using their large wings to deflect the ultrasonic signals of microbats.
