No, lizards aren’t amphibians, they are reptiles. Reptiles are covered with scales, scutes or plates; on the fingers they have claws. Amphibians have moist skin, rich in glands; They do not have claws. Eggs of reptiles are surrounded by a thick hard shell or shell, similar to parchment, which protects the embryo from loss of moisture even on dry land.
The eggs of the amphibians are devoid of a solid protective shell; Amphibians lay eggs in water or in wet places. Young reptiles are miniature copies of their parents (perhaps with the exception of coloring).
Young individuals of amphibians pass through the larval stage (usually aquatic), and then through metamorphosis (change in the shape and structure of the body), turning into an adult. Reptiles include alligators, crocodiles, turtles and snakes. Amphibians include salamanders, toads and frogs.
With some knowledge of the sexual characteristics of lizards, you can easily determine to which sex this or that individual belongs. If we consider basilisks, sailing lizards, water agamas and green iguanas, then a comb immediately flashes into our eyes, adorning the heads and backs of the males.
And if you take the chameleon lizards, then the males can be easily identified by cutaneous outgrowth, located on their heads. Male iguanas can be identified by guttural flaps or by significantly enlarged scales located behind the cloaca.
