? 1. Oviparous: Most lizards reproduce in an oviparous manner, usually at the end of spring and the beginning of summer. Specifically, when lizards are fertilized, they use internal fertilization. When the breeding season comes, male lizards will mate with female lizards with copulatory organs to complete the fertilization process. Because sperm activity is relatively high, female lizards can lay eggs many times after mating, sometimes even for several years in a row. Next comes the process of laying eggs by female lizards, which first find a warm, moist and hidden place that is not easy to be found by natural enemies, and then lay eggs. The number of eggs laid by female lizards varies from one to a dozen at a time.
2. Ovoviviparous: There are many species of lizards, not all of which are oviparous, and some species have different reproductive patterns, which are ovoviviparous. The process of fertilization is similar to that of oviposition, but the fertilized egg develops inside the female. Nevertheless, ovoviviparous is not viviparous, and the nutrition of the young is not provided directly by the placenta of the mother, but by the egg itself. The mother's body can provide a suitable environment for the development of fertilized eggs, so the probability of survival of larvae is relatively high.
? 1. Look at the tail: the tail of male and female lizards is different. Males tend to have longer and thicker tails, while females have shorter tails.
2. Look at the abdomen: The abdomen of the two is also different, especially after sexual maturity, it is easy to distinguish the male from the female from the abdomen. Male lizards have a narrow abdomen, while females have a more rounded abdomen.
3. Look at the reproductive foramen: The size and shape of the reproductive foramen of male and female are also different, which can be observed during the breeding season. The gonopore of male lizards is relatively small and round in shape, while the gonopore of female lizards is relatively large and square.
4. Look at the color: The color of lizards of different sexes is also different. The male color is more beautiful and gorgeous, while the female color is darker.
