Through Skin..
it dies and lives again.
Tadpoles breath through their gills.
Spring time.
because they go hibernation
frogs usually sleep under rocks,deep lakes or maybey a pond!.....=/
frogs breathe through there skins. but the frog has lungs but no ribs! They don't. Frogs can hold their breath for a very long time but they still have to come to the surface to breath air.They don't, they hold their breath like we do, they can just do it a long time. During their tadpole stage, they breathe under water through their skin, using internal gills. When they mature into frogs, they develop lungs and then can only breathe air using their lungs.
on land , frogs breathe with the help of lungs , and in water , with the help of gills.
Actually frogs dont breathe from their lungs. They have lungs but they don't use them because their skin is so thin that they can breathe from it.
Frogs and Toads need to hibernate to escape the winter so they dig into the ground up to 3 feet down to avoid the frost during the winter. Some frogs try to find a deep enough body of water that wont completely freeze solid and they can hibernate under the ice. Toads on the other hand will always dig into the ground and are great at digging. It's all to prepare for hibernation because insects don't come out during the winter so there's no food for toads and frogs. They start preparing to find a place during the fall.
Frogs have lungs just like you do. Tadpoles, however, have internal gills until they turn into frogs. Frogs breathe by pulsing their throat to suck air into and out of their lungs.
The difference between hibernation and estivation. Hibernation - when animals such as mice and bees and chipmunks and such sleep during winter and live off of fat and food energy that they store for when they go into a deep sleep. Estivation - when animals such as frogs and toads go into a deep sleep when it gets too warm.
Frogs Do live underwater because as tadpoles and froglets, they live under water until their gills disappear
I would think they breathe with there mouth underwater.
