EARS Although these may not be obvious, tortoises do have ears. Look along outside of-the neck on each side of the head; there should be two dark circular markings. These should be smooth - any lumps or swellings could indicate an ear abscess. http://www.britishcheloniagroup.org.uk/caresheets/advice.htm Turtles and tortoises do not have ears like ours, but they can feel vibrations and changes in water pressure that tell them where food, or a predator, might be. http://www.sandiegozoo.org/animalbytes/t-turtle.html

Turtles have more of a sound vibration locator, though I guess technically that is what all ears do. But there's is way in their heads.They can hear in the 200 and 800 hertz range. Scientist don't know why they hear, of what benefit it has for them becasuse they have acute sight and smell. That's how they really 'see' the world around them. I remember when we used to try to sneek up on some turtles sunning on a huge log at the pond next door. We thought that if we were as quiet as can be, they wouldn't all plop off the log. No matter how quiet we were, didn't matter, they'd plop in and swim. THen we found out that it wasn't hearing at all. That actually they could smeel us from a far. That was why it always seemed to happen at the same place. THey'd catch a whiff of us. But I wonder still why turtles needed such swift radar because they seem to have so few predators in fresh water once they are big. Must be leftover from their 'little' stage.
