What are the similarities between a lizard and a newt? how do they differ?

Both of these creatures are similar only in appearance, but if we look at them closer to us, their difference will immediately become clear.
So, both creatures belong to different classes, the lizard breathes only with the lungs, while the newt also has gills.
The newt spends most of its life in water, and reproduces there.
The lizard is exclusively terrestrial and lays eggs only on land. The lizard can also throw off its tail in case of danger, but the newt does not have such an ability. The newt is covered with smooth, slimy skin, while the lizard has scales instead.
