Wholesale Small Empty Red Eared Slider Turtle Shells in bulk.  They measure between 2-1/2 and 4 inches in length (some may be a little larger).   These turtle shells are real - not replicas.    Some may have a little dried algae on them.  The shells of the red eared slider turtle are used in Native American crafts.  The red eared slider is a cold-blooded animal and will usually be found during the day sitting in the sun on a rock, log, or any stumps that are near the water. Some red eared sliders can even be found up to three high basking in the sun. While the red eared slider is very hard of hearing they are sensitive to vibration they are very alert while they are basking. These vibrations allow the red eared slider the time to make their hasty retreat into the water if they feel threatened in any way.
