Chinese Frog and Ultrasonic Communication

The first non-mammalian species known to use the ultra-high frequencies that humans cannot hear has been discovered. The pride of place goes to a rare Chinese frog, Amolops tormotus. In the mammalian world Bats, whales and dolphins use it to communicate. Kraig Adler, a biologist at Cornell University in New York, first noticed the frog with no external eardrums while surveying amphibians in China. Detailed study and confirmation regarding use of ultrasonic waves was done by Professor Albert Feng of the University of Illinois
