Turtles are adjusted to living in all types of [[environment]]s. [[Freshwater]] turtles can be found in [[pond]]s, [[lake]]s and [[river]]s, [[marine]] turtles in the [[ocean]]s and [[sea]]s, and [[terrestrial]] turtles on [[land]]. There are also turtles that cross the borders between these environments, making them ''semi-terrestrial''.
