using their skin :})
They do indeed. I should also point out that crocs are reptiles, not amphibians.
Crocodiles have lungs and breathe air like humans. When a crocodile is submerged underwater, it can hold its breath for long periods of time by slowing its heart rate and relying on stored oxygen in its blood and muscles. When it surfaces, it quickly exhales and inhales, replenishing its oxygen supply.
Crocodiles have specialized muscles that allow them to open and close a flap in the back of their throat, called the glottis, allowing them to breathe while submerged underwater. They can hold their breath for extended periods of time by slowing down their metabolic rate and conserving oxygen.
For sure the young do and also alligators.
Crocodiles and alligators breathe in the water by raising their head and snout above the waters surface. Since they do not have gills, they have to hold their breath underwater. When hunting, only their eyes and snout are visible, making them look like a piece of driftwood.
they may have gills
they close it
They don't, any aquatic reptile needs to return to the surface to breathe after a while, the only creatures that can breather underwater are fish (and all their variants ie: sharks, stingrays etc)
Through their lungs ! The breathe air just as we do.
Crocodiles live in rivers, lakes and dams in parts of America, Asia, Africa and Australia. Crocodiles cannot breathe underwater: they breathe air, just like people. They can hold their breath for a maximum of about two hours underwater.
Birds, reptiles and most amphibians breathe through lungs.

Crocs don't breathe underwater. They have lungs and Breathe air pretty much just like you and I. They hold their breath when they dive.
No, birds and other reptiles like crocodiles also breathe air. Insects absorb air through their skin.
Many lower animals don't have noses and breathe through their skin.
they aren't born yet so they don't need to breath.
Through their lungs - just like every other air-breathing animal.
