So it can flick the tongue out long to catch prey
Because the saliva on the tongue is very sticky.
Its muscles cause it to curl up into his mouth. The tongue sits at the front of the mouth, rolled up, when not in use. Point worth noting: Not all frogs have long tongues. Ground frogs that eat ants etc. that are close to them do not.

So what do frogs eat? If you intend keeping frogs as pets then it is absolutely vital to know them well. Just like us, amphibians need a healthy diet - one that is nutritious and well-balanced. It is also very important that the right size of food and amount of food is given to your frog at the right time. When a frog is in the water, it is highly sensitive to movement around it, and this movement stimulates feeding. Therefore it is better that the prey offered to the frog (and other amphibians) is live. The terrestrial amphibian's tongue is sticky and is located at the front of it's mouth, and so it is able to shoot it's tongue out quickly to catch it's prey on the sticky tongue. Tree frogs and other amphibians stalk their prey and actively seek it. Other frogs will use their camouflage skills and lay in wait undetected until their unsuspecting prey passes their way and then strike!
