Singing frog’s ‘ultrasonic croak’
A rare Chinese frog has entered the record books as the first amphibian known to communicate using ultrasound.
Until now, only a few mammals – such as bats, whales and dolphins – have been found to use the very high frequency sound to contact each other.
The frog may have evolved the mechanism to be heard above the babble of running water, scientists tell this week’s edition of the journal Nature.
