vibrating and croaking after mate

Female are attracted to the male that makes the loudest call. Just like humans and other animals,they creates sound by blowing air out of its lungs. This thrust of air moves the frog's vocal cords (two pairs of folded tissue in the throat), causing air molecules to vibrate back and forth resulting a sound wave.

Imi place aceasta fotografie, apa da rezonanta- face valuri cu sunetul scos de broasca! Claritatea nu este perfecta, dar ca document, poza are o valoare deosebita!
