Interesting facts about frogs

Do frogs have teeth?



Actually, yes! But not like in this silly picture!
Most frogs do in fact have teeth of a sort.
They have a ridge of very small cone teeth around the upper edge of the jaw. These are called Maxillary Teeth.
Frogs often also have what are called Vomerine Teeth on the roof of their mouth.
They don't have anything that could be called teeth on their lower jaw, so they usually swallow their food whole. The so-called "teeth" are mainly used to hold the prey and keep it in place till they can get a good grip on it and squash their eyeballs down to swallow their meal.
Toads, however, do NOT have any teeth.



Can frogs hear?

Frogs can hear using big round ears on the sides of their head called a tympanum. Tympanum means drum. On some frogs, the ear is very hard to see!
Ever wonder how frogs that can get so LOUD manage not to hurt their own ears? Some frogs make so much noise that they can be heard for miles! How do they keep from blowing out their own eardrums?
Well, actually, frogs have special ears that are connected to their lungs. When they hear noises, not only does the eardrum vibrate, but the lung does too! Scientists think that this special pressure system is what keeps frogs from hurting themselves with their noisy calls!
