Summary:

• **Sea turtles have tiny ears that can hear underwater sounds.** Scientists discovered that the world's smallest sea turtle, called the speckled paddle-tail, uses special hearing abilities to navigate and find food in the ocean, even though their ears are very small and hidden inside their heads.

• **Ocean noise from ships and humans is a big problem for sea turtles.** Loud sounds from boats and other human activities in the ocean can confuse and hurt sea turtles, making it harder for them to survive and find their way around in the water.
