No they do not have gills.
Reptiles always breathe with lungs. Amphibians may breathe with lungs, gills or through their skin.
Yes some reptiles do have gills.
Yes, all reptiles breathe using lungs. If they are underwater they have to come to the surface to breathe. Amphibians (frogs, newts, salamanders etc) are NOT reptiles. Amphibians often breathe through their skin.
Elephants breathe with lungs.Most land animals breathe with lungs.All mammals breathe with lungs.All reptiles breathe with lungs .All birds breathe with lungs.Some amphibians breathe with lungs, while some do not.Only fish and marine crustaceans breathe with gills.
Mammals, birds, reptiles and adult amphibians breathe using lungs. Fish breathe using gills, while juvenile amphibians breathe using gills and spiracles.
The main differences between fish and reptiles are:fish breathe through gills and reptiles breathe through lungsFish have scales and reptiles have scaly skinFish must live in water but reptiles are terrestrial (except for turtles)
Fish obtain oxygen through their gills, allowing them to breathe underwater, while reptiles require air to breathe like we do. Marine reptiles, such as sea turtles, have to surface periodically for air.
Most reptiles exchange gases through their lungs. The lungs of reptiles are folded so as to make enough room for gaseous exchange.
Yes they do. The shells of the eggs are permeable - meaning it allows moisture and air to penetrate inside. The growing reptile absorbs oxygen through the egg membrane as it develops.
Only underwater snakes do. Not land snakes.
When amphibians are babies, they have gills, but most adult amphibians breathe with a pair of lungs excluding salamanders.
