Theoretically, frogs could stay underwater their whole lives... Though they have lungs to breathe atmosphere, they are also able to glean O2 out of the water through what is called cutaneous gas exchange, otherwise known as breathing through their skin.
I guess the exact time probably depends on the type of frog. Most frogs can stay completely submerged underwater for long periods of time. They absorb the oxygen in the water through their skin which allows them to breathe under there.
My small bull frog can stay under for 3 minutes at the maximum, the big one [3 in] on the other hand, can stay down for up to ten. It might depend how big the frog is.
3 hours for sure
Up to like 45 min. Max
For a long time because if the frog is larger it absorbs more oxygen than a small frog does
Depending on the frog, my frog never went up to air he lived for like 9 weeks then froze, I live in alaska, it was during the winter when he froze, and he was next to the window...
It deppends what kinda frog mine lives under water and can not go on land
A long time
I don't know but I have to find out because I have a frog the size of my pinky nail.
Maybe it depends on the kind of frog but they are just like fish they can hold it for a long long long time!!! I think!1
