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.
Some, yes. They use a combination of up to 3 types of respiration. Pulminary respiration with lungs, cutaneaous respiration through the skin and buccopharnygeal respiration which is through the nostrils or mouth and absorbed at the back of the throat so to speak.
Most salamanders breath through gills when they are young and through lungs when they are adults. Some retain their gills throughout their lives while others breath through thier skin as adults.
No. Salamanders are reptiles, so they have some form of lungs. Only fish have gills.
Yes, they have external gills meaning they can breathe underwater. Salamanders are amphibians not reptiles
yes
yes they do
Salamanders
salamanders have both
With their gills and skin, although some species of salamanders have lungs.
Those are its gills (e.g. for breathing). Salamanders such as the Axolotl have external gills, unlike internal gills found in fish.
be restricted to smaller and/or thinner body plans.
salamanders have both
Many frogs and salamanders start their lives with gills, but when they grow they develop lungs.
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.
No,salamanders are only in wet areas and Egypt is very dry and has scarcly any water so salamanders wouldn't survive there.
They once brathed with gills but have adapted and can be underwater for long time while holding its breathe. So they have lungs
