Posted by How long can frogs breathe underwater? Believe it or not they can actually stay underwater up to 24 hours without coming up to breathe again. A frog is an extremely fast swimming creature that is capable of swimming faster than the majority of all sharks and dolphins can swim. An adult male frog can normally hold its breath up to 4 hours while an adult human can usually hold their breath up to twice that.
Do salamanders have lungs? Salamanders and some turtles can breathe both underwater and on land. They do not have lungs like all amphibians, though; in fact all amphibians lungs are underwater. The lungs of salamanders and turtles are filled with tissues that help them carry oxygen in and oxygen out of their bodies while they are breathing and while they are resting.
How do frogs breathe through their nostrils? All frogs have small holes in their noses known as their olfactory pits and these pits can be used to detect food. However, the structures behind the olfactory pits are completely different from those of humans and all other amphibians. In humans and many other amphibians, the structures are located inside the nasal cavity, and they are connected to the respiratory system.
Can frogs go into a protective bubble when they are threatened? Yes, all frogs can breathe underwater, but only for a short period of time. The amount of time that a frog can stay underwater depends largely on the oxygen content of the water in which the frog resides. Fishes and snails that live in low oxygen water will often stay in a protective bubble and then retreat back to the deeper parts of the body of water where they will get more oxygen. On the other hand, most frogs can go right up to the surface of the water and breathe completely underwater.
Why don’t frogs have lungs like us? There is one factor that really helps. The small bumps on the side of their head (called pinnae) serve as their respiratory organ. Just think of a tiny flower that has tiny pins sticking out of its head – that is the tongue. When the frog sucks air (which it does when it’s frightened or stressed), it uses its tongue to push air down its throat and into its lungs. The same mechanism applies to the mouth.
Why do some frogs (head-nose breathers) have no apparent trace of underpasses? The reason is rather simple – they use their skin breathing process, also called respiration, to stay submerged. Oxygen is carried to their mouth by tiny hairs called cilia. As these cilia move over the skin on their head, they pull oxygen molecules up into the air where the dissolved oxygen mixes with water vapor to create carbon dioxide. The rest of the body, including the lungs, takes in carbon dioxide, breathing atmospheric air, and exhaling carbon dioxide (and oxygen).
