Aves
-
Amphibia
-
Mammalia
-
Reptilia
The characteristics of salamanders are as followed:
- They have soft, wet skin like a frog to adapt in a wet environment.
- They lay spawns where the tadpoles will hatch like frogs.
- Also, they have gills, lungs for respiration in water and land respectively.
- These are main characteristics that Amphibians show.
Aves are birds and salamanders aren't one of them. Salamanders lay eggs so they can't be grouped under Mammalia. Reptiles have no wet skins, respiration is through lungs(absence of gills).
So, the correct answer is 'Amphibia'.
