Singing Frog
Chinese frog that squeaks like a mouse
A frog that sings like a bird has been found to have another unusual trait - it can communicate in high-pitched squeaks that are inaudible to the human ear. The frog lives in the fast-moving streams and waterfalls of east-central China and uses ultrasonic calls to make itself heard above the noise of running water.

Very interesting! It is amazing the variety of exotic animals you can find around the world, just the fact a frog can "sing" it's just beyond imagination. This is also a very interesting part of the article:

The human ear cannot hear sounds with frequencies higher than 20 kilohertz but the frog has been recorded emitting sounds higher than 128kH which can carry above the noise of splashing water. |
