Some methods can be used to detect it. Find a sharp object and gently touch its creaking nest. If it reacts, it means it is not dead yet.

1. Natural death: Although it is said that the turtles are eighty thousand years old, the life span of turtles is far from so long. Generally, Brazilian turtles can live for about 15-25 years, so if they have been raised for so long, they may die naturally. If it is properly raised and managed, it can also live longer.

2. Disease factors: If the tortoise is not treated in time, it will also die. There are many diseases that threaten it, such as white eye disease, skin rot disease, nail rot disease, pneumonia, etc. Generally, after it is found to be sick, it needs to be dry raised, soaked in water several times a day, and treated with drugs at the same time.

3. Environmental change: Environmental change will also lead to the death of Brazilian tortoise. For example, water quality deterioration, temperature fluctuation and other factors will affect its survival. Therefore, we must pay attention to changing water and controlling temperature at the same time, and the minimum temperature should not be lower than 5 ℃, so that it can grow healthily.
