Hector, one of my ml Red Eared Sliders. In this shot you can see were they get part of their name from. That long red spot, which is found on both sides of their heads. One thing you don't see though is any external ear opening. But they do have the auditory nerve and brain center required for hearing. Turtles do not hear airborne sounds as loudly as a person does, but they can sense and interpret vibrations in the environment. A turtles sense of smell and eye sight is very good so it makes up for the lack of good hearing.
