So they can see there prey, insects, and be able to catch them.
Frogs have the eyes and noses on the top of their head so they can see their prey and can see while their bodies are submerged under water.
They don't need to see in order to swallow. The frogs just closes their eyes and swallows. Many animals close their eyes when they are eating live prey. They do so, in order that their prey can't injure their eyes while they are being eaten.
Yes and no depending on which frog ,normally if the frog is poisonous their eyes are big so they can defend their selfs better,And if they are normal frogs There about as big as your pinky nail
I think so they do have Compound eyes which they cannot close there eyes but when they sleep they need to rise up to the surface to get water.
Four-eyed frogs, specifically the species Lepidobatrachus llanensis, do not have four functional eyes. They possess two regular eyes and two additional photoreceptive organs on the top of their heads, which are not true eyes but rather light-sensitive structures. These additional organs help the frogs detect light and shadows, aiding in their environment navigation. So, while they are called "four-eyed," they do not have four traditional eyes.
The nictitating membrane is a translucent third eyelid in frogs that provides protection and helps keep their eyes moist. It acts as a protective barrier while allowing some visibility, enabling frogs to see basic shapes and movements even when their eyes are covered.
Frogs have an important ecological role as eaters of insects. There is also a certain cuteness about them. They are the inspiration for Kermit the frog.
frogs can turn their eyes in different directions to see whats behind,in front and on the sides of them so they can see you from different directions. they can even see you from behind when the frog is facing forward!
it really depends usually 1-2 hours at a time.
Their eyes can go back inside their heads. this is because of the muscle behind their eyelids. A frogs eyes are also located very high on their head so there eyes are almost never in the water.
i think frogs are important to other living things because they eat the insects so the insects won't give us disease that's all what i knowthank you!!!
no one knows even scientist don't. maybe they will, in the future.
