Frog mouth move with croakbladder that can blow you up
Did you know? That frogs have a croakbladder? Maybe you've been to a pond where the frogs give a loud croak concert. One frog makes almost even more noise than the other. What a croakbladder is? It is a strong stretchable skin. The males frogs have 1 or 2. Or they have a 1 throat bladder and otherwise 2 cheek blowing. They have these to find other females and thus be able to lure. The blowing is getting very big and it looks like the frog is about to explode! Luckily, that doesn't happen, but when you hear the noise of their croaking..
When croaking, air is fed along the larynx, bringing the vocal cords into vibration. So that gives the specific sound. And then every species has its own sound.
Now it is of course also nice to make such a frog. We mimic it with a plastic bag as a croakbladder. At the BSO has Nathalie Mensink prepared this for the children so that they can make their own frog. Read how it was made?
