Do turtles have a good sense of smell?
Yes they do; they use their sense of smell to find and identify food, mates, territory etc. On land turtles smell things the way we do but under water many have special little bumps or barbels on their chins that contain olfactory (sense of smell) nerve endings to help them find food in dark or muddy water. Tiny Painted Turtles, for example, are born knowing that the smell of a Snapping Turtle means danger and they react to fast movement by diving for cover.
