The turtle doesn’t have a voice in the way we usually think of a voice. but many turtles, such as the giant land turtle, can hiss, crunt and even roar loudly.
Turtles are animals that are easy to recognized by their shells.
If you own a pet turtle, you have probably noticed that the turtle never seems to “talk”. You may wonder if it has a voice at all.
In the way we usually think of a voice, the answer is “no”, as far as most turtles are concerned.
Turtles seldom emit sounds, except during the nesting season. Even then many can do little more that make a feeble piping sound or grunting to loud roaring, which can be heard for a quarter of a mile.
Some turtles hiss loudly when they are alarmed.
A few sea turtles can five a loud cry of anger or a “plea for mercy” when captured by an enemy.
Most turtles apparently have good eyes sight and a good sense of smell and taste. However, turtles do not hear well. Some kinds may be deaf. – Dick Rogers
