These turtles spend most of their time in ponds and streams. However, because they are ectotherms - meaning they get their energy from the sun - they come out every once in a while to bask in the sunlight. During the winter time when there is less sunlight, these turtles sink to the bottom of their habitat and become inactive, eating sparingly. This is called brumation and is very similar to hibernation. Due to their strong legs and webbed feet, Red Eared Slider Turtles are very good swimmers and can hold their breath underwater for long periods.
