Which of the following his sensitive Ultrasonic waves
Answers
I think u want to know which animals can produce ultrasonic waves!! (assuming 'his' as 'has' and unable to find any options)
In that case, Bats(Chiroptera); Dolphins(Delphinus); Whales(Balaenidae & others); Moths; Mice; Frogs; Grasshopper(Caelifera) are the living creatures which produce ultrasonic waves. Although the purpose of the sound production may differ, but the sound produced by each helps them to survive in various ways.
The sound in the form of waves that humans cannot hear as the frequency is more than human hearing forms the ultrasound waves.
The ultrasonic waves or the sound begins above 20000 HZ which is the benchmark for a human hearing ad they cannot hear it.
Some animals like dogs, dolphins, and frogs can hear ultrasonic sounds.
