Brazilian tortoises bite when they grow up, because their nature is fierce. When they are in the wild, they compete for food and fight fiercely. However, captive Brazilian tortoises generally do not bite, because most of them lose their wildness and ferocity after long-term captive breeding, so they will not bite under normal circumstances. If they are extremely hungry, they may bite. In addition to hunger, they also bite when they are angry. Breeders should pay attention in the usual breeding process, and don't tease them hard, otherwise they may be injured.

If the breeder is accidentally bitten by the tortoise, don't pull hard, so not only people will be injured, but also the tortoise will be injured. After being bitten, you can knock their carapace or poke them in the eye, so that they will let go quickly. After loosening the mouth, the breeder can wash and wipe it with alcohol or soapy water.

To make tortoises obedient, train them when they are fed. But the training is also gradual. First, they can be fed normally, but they can watch while they eat, so that they can familiarize themselves with the existence of their owners. When they know that their owners are no longer hurting them, they start to be bold. At this time, breeders can also feed them with food in their hands. After Brazilian tortoises form conditioned reflex, they can be trained when feeding. For example, let them shake hands and nod their heads.
