Brazilian tortoise and grass tortoise cannot reproduce because they are not the same species of tortoise. Brazilian tortoise is a tortoise of Brazilian tortoise species, belonging to the genus Colored Tortoise, of the suborder Curved-necked Tortoise. The grass turtle is a turtle of the suborder Curved-necked Turtle, the family Turtle, the genus Turtle and the grass turtle. There is reproductive isolation between these two turtles. In principle, the germ cells of Brazilian turtles and grass turtles cannot fit, that is to say, their chromosomes cannot be completely paired. Therefore, even after mating, it is difficult for them to breed offspring. Even if they can reproduce offspring, their offspring can no longer reproduce.

Brazilian tortoises begin to reproduce when the weather warms up. If breeders want them to reproduce, they must put mature male tortoises and female tortoises together and let them pair themselves. After successful mating, the Brazilian tortoise begins to mate. When mating, the male tortoise will lie prone on the back of the female tortoise and put its genitals in the release hole of the female tortoise. At this time, mating is completed.

After mating for some time, the tortoise is ready to lay eggs. Before laying eggs, they will choose a soft land, dig out a pit first, and then lay eggs in it. When they die, they fill the pit with soil and finally leave. Brazilian tortoises don't have the habit of keeping their holes. After they lay eggs, breeders need to take them out and put them into a special incubator for hatching.
