Some frogs scream at an ear-splitting volume for other animals but its frequency is inaudible to humans, scientists have discovered.<\/p>\n

While out in the Amazonian jungle studying frogs, researchers in Brazil<\/a><\/strong> noticed something strange.<\/p>\n

Small leaf litter frogs were arching their backs, throwing back their heads and opening their mouths wide.<\/p>\n

They looked like they were screaming but the scientists could hear nothing.<\/p>\n

When they recorded the frogs using high-frequency audio recorders, the scientists captured the first documented case of “defensive ultrasound” being used by amphibians.<\/p>\n

The scream is a response to predators, according to researchers from Brazil’s State University of Campinas.<\/p>\n

It could be a call to arms to attract another animal to attack the predator.<\/p>\n

The researchers recorded the distress call on two occasions.<\/p>\n

When they analysed the sound using special software, they found that it had a frequency range of 7 kilohertz (kHz) to 44 kHz.<\/p>\n

Humans cannot hear frequencies higher than 20 kHz, which are classed as ultrasound.<\/p>\n

A researcher on the team, Mariana Retuci Pontes, says she saw frogs exhibiting similar behaviour on a different research trip but didn’t have the right technology to record the ultrasonic sound.<\/p>\n

Bats, whales, rhinos, dogs, pigeons, cuttlefish\u2026 all sorts of animals use infrasonic and ultrasonic frequencies to communicate, and humans can hear none of it.<\/p>\n

So the next time you’re enjoying a peaceful walk, all around you there could be a cacophony of noise.<\/p>\n<\/p><\/div>\n
