Are baby turtles on their own when they hatch?

If you are talking about sea turtles, they just head out to the sea even though they never saw anyone do that besides themselves or their brothers and sisters. It is an inherited behavior. They just do it automatically. And pet and freshwater turtles just go inside. They get out of the place they were hatched, and then they go into the water to cool and wash themselves. This behavior is inherited.

Baby sea turtles use the presence of natural moonlight to find their way to the coast at night. This is why coastal light pollution is such a problem because it disorients the baby turtles.
