The Mole Cricket

The sound that we often hear, especially on the eastern side of Australia, is this other animal called the mole cricket. They're excrement, they're liquid stuff can fill 300 Olympic sized bulls per day. And after they die, they leave behind over 500 trillion eggs - about a thousand times more than there are stars in the Milky Way. It turns out that male saccatas make noise in the same way that a wobble board does.
