Turtles can bask in the sun. For most turtles, it is necessary to bask in the sun, which can not only sterilize and disinfect, but also promote metabolism and benefit calcium absorption. However, some deep-water turtles need less light, so it doesn't matter if they don't bask in the sun. For example, pig-nosed turtles and crocodile turtles live in the water for a long time, and they hardly go ashore except for breeding, so they don't bask in the sun very much.

1. Sterilization and disinfection: The most direct benefit of basking in the sun is sterilization and disinfection. Because turtles are soaked in water for a long time, there will inevitably be some bacteria and fungi in the water, so all the harmful bacteria on the turtle's back can be killed by basking in the sun, preventing the occurrence of some diseases, which is of great help to their health.

2, promote metabolism: The sun can raise the temperature, thus promoting metabolism, which is beneficial to the growth of turtles. And when you bask in the sun, turtles will be more energetic. However, in order to prevent it from dehydration, it is best to prepare a pool nearby so that it can replenish water.

3. Calcium absorption: By basking in the sun, it can also promote the synthesis of vitamin D3 in turtles, which is especially important for turtles because it can accelerate the absorption of calcium, which can prevent soft nail disease and make turtles develop healthily.
