Yes.
They have a larval and adult life, have moist skin, larvae have gills while adults have lungs, and they perform amplexus to mate.
In most species Amphibians hatch as aquatic larvae with gills and then undergo metamorphosis into four-legged terrestrial adults with lungs for breathing air.
yes they have lungs to breathe
They grow lungs, and lose their gills.
They grow lungs, and lose their gills.
The life cycle of the Chinese giant salamander begins with the female laying eggs in freshwater environments, often in crevices or under rocks. The eggs hatch into aquatic larvae, which possess external gills and can remain in this stage for several years. As they mature, they undergo metamorphosis, developing lungs and transitioning to a more terrestrial adult form. Adult Chinese giant salamanders typically live in rivers and streams, where they can reach impressive sizes and live for several decades.
the stage is the salamander develops working lungs
Amphibian larvae use gills to obtain oxygen from the water they live in, then during metamorphosis, most amphibians lose their gills, and grow lungs.
frogs undergo incomplete metamorphosis because they do not go through a third stage.In frog development, the eggs hatch and give rise to tadpoles, small aquatic larvae that have external gills and are mainly vegetarian. As the tadpole grows, internal gills and limbs form. Several significant changes occur during metamorphosis into the adult, including growth of a large mouth and tongue, loss of gills, formation of lungs, growth of the front legs, and resorption of the tail. Numerous biochemical changes accompany these morphological changes, such as synthesis of a new visual pigment in the eyes and a new oxygen-binding hemoglobin protein in the blood. The adult is mainly insectivorous and partly terrestrialRead more: Metamorphosis - Amphibians - Adult, Changes, Gills, and Development - JRank Articles http://science.jrank.org/pages/4276/Metamorphosis-Amphibians.html#ixzz2UadIy4hP
the salamander.
Yes, tiger salamanders undergo metamorphosis. They start their life as aquatic larvae with gills and gradually transform into terrestrial adults with lungs. This process involves significant changes in their body structure, allowing them to adapt to life on land. Metamorphosis can be influenced by environmental factors, such as habitat conditions and food availability.
Only underwater snakes do. Not land snakes.
