They don't have ears like ours that stick out on the sides of the head. But they actually have 3 "ears", 2 little holes in the sides of their head and one on the nose. And they have an auditory nerve that signals the brain. They don't hear as we do but sense vibrations and learn from them. Turtles have very strong senses of smell and vision and rely mainly on those senses, making hearing not as important.
