Frog hearing and communication. Frogs and toads produce a rich variety of sounds, calls, and songs during their courtship and mating rituals. The callers, usually males, make stereotyped sounds in order to advertise their location, their mating readiness and their willingness to defend their territory; listeners respond to the calls by return ...
Acoustic communication is the use of sound as signals. Acoustic communication is widespread in both aquatic and semi-aquatic invertebrates and vertebrates, [5] with many species capable of using both infrasound and ultrasound for communication. As sound travels faster and over a larger distance in water than in air, aquatic animals can use ...
Frogs can hear both in the air and below water. They do not have external ears; the eardrums (tympanic membranes) are directly exposed or may be covered by a layer of skin and are visible as a circular area just behind the eye. The size and distance apart of the eardrums is related to the frequency and wavelength at which the frog calls.
“If you hear frogs at one of these lakes, it’s the Pacific tree frog,” Knapp said. But that doesn’t mean that they’re not making sound – you just have to stick your head under water to ...

Pipid frogs are highly aquatic and have numerous morphological modifications befitting their habitat. For example, the feet are completely webbed, the body is flattened, and a lateral line system is present in adults. [1] In addition, pipids possess highly modified ears for producing and receiving sound under water.
Animal echolocation. Echolocation, also called bio sonar, is a biological active sonar used by several animal groups, both in the air and underwater. Echolocating animals emit calls and listen to the echoes of those calls that return from various objects near them. They use these echoes to locate and identify the objects.
Bioacoustics is a cross-disciplinary science that combines biology and acoustics. Usually it refers to the investigation of sound production, dispersion and reception in animals (including humans). [1] This involves neurophysiological and anatomical basis of sound production and detection, and relation of acoustic signals to the medium they ...
