It helps them swallow their food.
Frogs use the muscles of their eyes and pull their eyeballs down which pushes the pray down. The tongue is rather used for catching and holding the pray. Tongueless frogs (Pipidae) push their food in their mouth with there front legs. This looks strange, as the frogs 'eats with his hands'.
Insects, amphibians, such as frogs, toads and newts, fish, such as lampreys and flatfish which can start with eyes on either side of the body, but then end up with both eyes on the same side, and certain eels.
retract
frogs do live on land. not all species of frogs live in water.
Yes, they do eat frogs.
They retract their eyes down into their throats to push the food down.
It's not so much as how they retract their eyes (im pretty sure they use muscles for that) as to what the eye retraction actually does. Frogs actually retract their eyes in order to swallow. Their eyes get pulled into the sockets and bulge in the top of their mouths, which helps them swallow. It is strange, but true. XD
9578. Last I checked, frogs had two eyes each. Multiply the number of frogs by 2, genius.
big eyes
No.
According to biologists, the protruding eyes of a frog help it to see all of its surrounding day and night. In addition, the eyes are water resistant and the frogs are able to rotate their eyes because they are unable to turn their heads around when detecting approaching predators.
yes
No.
No it stickes
Yes!
You don't make a frogs eye bulge.
No, frogs usually close their eyes when swallowing their food. The muscles related to their eyes help them in the process of gulping food down their throat.
