1 of 3 Skin
Lizards have dry skin that is covered in scales, which helps them to retain water in arid environments. Salamanders, on the other hand, typically have moist, porous skin that is permeable to water in the wet habitats where they live.
2 of 3 Claws
With the exception of a few legless species, lizards have claws on their toes, which come in handy in their terrestrial habitats. Salamanders lack claws on their toes.
3 of 3 Ear Openings
Lizards have ear openings; salamanders do not, but still have inner ears.
