英語聽力：完美捕食—3

Triceratops protects itself with a bony shield called a frill. They can fend off an attacker with a pair of one-meter-long swords.

You’ve got to crush it. The only way to deal with this huge, curved, cantilevered, composite armor is a crushing blow with multiple teeth.

But defeating a Triceratops takes more than just teeth. It also requires power. Triceratops’ most dangerous weapons are mounted on a skull that can swivel 360 degrees.

Triceratops would want to keep that horns and the frill pointed right at T-Rex.

For a T-Rex, the key to defeating a Triceratops is his huge jaws, driven by two sets of powerful muscles. The first runs from the top of the skull down to the bottom of the jaw. These muscles give this carnivore’s bite its spear. The second set are muscles which make up almost 50% of the muscles in the head, and wrap around the lower jaw, tying it to the roof of the mouth. They give T-Rex’s bite its 3 tons of force, twice the biting power of a great white shark. And not only that. Just like a python, T-Rex can dislocate its jaw.

Cranial kinesis is basically the ability to swallow things larger than your own head. That’s because the skull expands as it opens up—snakes swallowing whole chicken eggs. A snake head that’s, you know, much smaller than the egg, and it will swallow that whole egg. There’s not a lawyer in this world that’s too fat that this T-Rex couldn’t swallow him whole.

Tyrannosaurus Rex is a carnivorous monster that uses sheer force to overpower well-defended prey.
