NEW DELHI: A new study claims to have documented the “first” case of an ultrasonic ‘distress call’ made by a Brazilian frog species’ for self-defence.
While humans would be incapable of hearing this scream, researchers said the distress call had an “ear-piercing intensity” for many animals, including predators of amphibians such as bats, rodents and small primates — all of which can emit and hear sounds in the ultrasonic range.
The research team studied the screams of leaf litter frog (Haddadus binotatus), a species endemic to the Brazilian Atlantic Rainforest.
