Which of the following animals cannot stick out its tongue?
Anteater
Giraffe
Crocodile
Kangaroo
Fact: Unlike most animals, crocodiles cannot stick out their tongues because the tongue is held firmly in place by a membrane attached to the floor of the mouth. While the tongue can move slightly inside the mouth, it cannot extend beyond the jaws. This unique adaptation helps prevent water from entering the throat while the crocodile is submerged and makes it easier to grip struggling prey. Crocodiles have survived with this unusual feature for more than 200 million years, making them one of Earth’s oldest and most successful predators.
Correct Answer: Crocodile
