There are many different varieties of salamanders. Most of these salamanders have both gills, and lungs. There are also some that have gills, but then lose them as they get older. They then use lungs for breathing.
Salamanders
salamanders have both
Those are its gills (e.g. for breathing). Salamanders such as the Axolotl have external gills, unlike internal gills found in fish.
With their gills and skin, although some species of salamanders have lungs.
Amphibians, such as frogs and salamanders, begin life with gills for underwater breathing and later develop lungs to breathe on land as they mature. This transition from gills to lungs is part of their metamorphosis process.
be restricted to smaller and/or thinner body plans.
salamanders have both
Not all amphibians do, some salamanders are live-bearers and some frogs lack a larval stage, they leave their egg as a small frog. Most amphibians do have a larval stage with gills, some will never drop the gills (neonetism) and most frogs and some salamanders will develop lungs. Most salamanders dont have lungs and breathe through their skin. There is no specified reason for having gills and lungs at different stages of their life cycle; apparently it is a good strategy. If it wasn't, frogs would be extinct ;)
Most salamanders lay eggs. Almost all amphibians do.Nearly all salamanders lay eggs. However, there are a few salamanders that give birth to live young.Some salamanders lay eggs in water. These eggs hatch into salamander larvae with gills. Other salamanders lay eggs in land. Usually these eggs hatch into tiny terrestrial salamanders that do not have gills.
Mudpuppies and waterdogs are large neotonous salamanders (salamanders that retain their gills in adulthood). Often used for bait in fishing they are generally green or brown in color. Mudpuppies are Necturus maculosus of the family Proteidae and remain neotonous. Waterdogs can mature into tiger salamanders.
Salamanders undergo a process called metamorphosis, starting from eggs laid in water. The eggs hatch into larvae, commonly known as "tadpoles," which have gills for breathing underwater and often possess tails for swimming. As they mature, larvae gradually develop lungs, lose their gills, and undergo physical changes such as the development of limbs. Eventually, they emerge from the water as fully formed adult salamanders, capable of living on land.
No,salamanders are only in wet areas and Egypt is very dry and has scarcly any water so salamanders wouldn't survive there.
