Animals That Communicate Using Infrasonic Sounds
Bats Bats aren’t really blood-sucking, blind vampires, although they are often portrayed that way. But bats do use echolocation for hunting and for navigation. Echolocation is when bats emit very high-pitched noises, which bounce off of objects and their prey and bounce back to their ears.
Moths Completely surprised to know that moths have such acute hearing. In fact, the Greater Wax Moth probably has the best hearing in all of the known animal world. Their hearing is so good that they can hear bats’ echolocation and escape from being a bat dinner.
Praying Mantis Moths aren’t the only bugs on the ultrasound list! Praying mantises, once thought to be completely deaf, actually have a single ear located in their thorax or chest area. And according to the National Wildlife Federation, they can hear sounds as high as a bat’s chirp, giving them the chance to escape being preyed upon.
Dolphins Dolphins can also use echolocation to communicate, but they are able to send out two frequencies simultaneously. Science Daily believes that dolphins must have two distinct sound-producing organs, rather than just one. They use these sounds to communicate with each other.
Frogs and Toads Frogs and toads also make use of ultrasonic noises. For example, the torrent frog lives among noisy waterfalls that make it hard to hear lower-pitched sounds.
Tarsiers Tarsiers are tiny primates that use ultrasonic sounds to find their dinner and hide from predators. Tarsiers dine on insects such as katydids, which also use ultrasonic noises.
Cattle Cattle have extremely sensitive hearing and can hear frequencies much higher than even a dog whistle can produce. When nervous or scared, they can produce pheromones in their excrement, which tells other cattle there is danger.
