The leaf frog (Haddadus binotatus) is the most common frog species in forest communities. Although they are numerous, they are small. The largest of them is the female, and their length barely reaches 64 millimeters. When they are attacked, they cannot fight back, so they scream by emitting an ultrasonic danger signal as a way of defense.
We have long known that some frogs use their mouths to signal distress, warning and alarm, and although several studies have found that frogs can emit ultrasound, this new study is the first to confirm this.
Some potential predators of amphibians, such as bats, rodents, and small primates, can produce and hear sounds at this frequency, which humans cannot. One of our hypotheses is that the distress signal is sent to some of them. [тварин]but it is also possible that it is universal in the sense that its wide frequency band scares away as many predators as possible.
– says Ubirata Ferreira Souza, who studies animal behavior from the State University of Campinas in Brazil.
This cry is part of a series of defensive actions in which the leaf frog arches its back and lifts the front of its body. Then he opens his mouth wide and finally lets out a high-pitched scream with his mouth partially closed.
While humans can only hear sounds at frequencies of about 20 kilohertz and below, the software Souza and his team used to record the frog’s cry showed that: Varies from 7 to 44 kilohertz.
Scientists believe that such a wide frequency range, as well as the frog’s intimidating stance, are intended to deter a wide range of predators from coming into contact with this small creature. This behavior may be more common than we think, as other frogs capable of such powerful calls have been discovered elsewhere in the world.
The exact mechanisms by which screams deter predators are unclear, but they suggest it may be either a direct auditory deterrent or even attract the predator’s natural enemies. So in this way, a frog can call an owl, for example, to attack a snake that will eat the frog.
