Map turtles of all kinds are avid baskers, spending many hours during the day in the sun. When with other turtles, they also are very communal, sharing space and using each other for predator watching, increasing the odds of surviving an attack by any unwanted animal. But this does not mean that they are social reptiles, turtles are loners.
