Lizards (reptiles) and newts (amphibians) belong to completely different classes. To distinguish them you need to try hard and take a closer look. Outwardly, these two animals are strikingly similar in the elongated shape of the body, head and tail. Both have a three-chambered heart, there are 2 circles of blood circulation, however, in lizards an incomplete septum appears and a second ventricle is secreted. The head is the same and resembles the head of a snake with eyelids, the tail is long, different colors of the body of these animals adapt to the environment, there may still be a crest on the back in some species. This is where the similarities end and the differences begin, which are much more. Skin: lizards have scales, newts have smooth, mucus-covered skin. Breathing in newts is carried out by the gills, skin and lungs, and in lizards only by the lungs.
