Answer 1

Crocodiles have 64 teeth, yet they are continually being supplanted. A crocodile can experience more than 3,000 teeth in a lifetime. Every tooth is empty, with new ones becoming inside the old ones.

Complete Answer:

Crocodiles are among the biggest hunters on the planet; in outstanding cases, they may surpass a 22 feet long body and have a 2200 pounds body. Crocodiles are trap hunters who use disguise and persistence to go after creatures as different as fish, warm-blooded animals, and fowls. Crocodiles utilize their extraordinarily long teeth and solid jaws to clip down on prey, guaranteeing it can't escape. Crocodilians, though belonging to Class Reptilia, possess several unique characters present only in the members of the order loricata, and teeth are one of them. Teeth in crocodilians are homodont i.e all teeth are similar in shape and thecodont i.e. embedded in the socket. Each tooth is fixed individually in a pit-like socket present both in the upper and lower jaw. Saltwater crocodiles (Crocodylus porosus), the biggest living species, have colossal canine teeth, surpassing 44 crawls in enormous examples. Hatchling crocodiles have sharp, little teeth, close to a quarter-inch long, which helps them to grasp tricky frogs, fish, and worms. Crocodiles supplant their teeth persistently, as they lose numerous in fights with prey and conspecifics.

The muscles that are near the jaws are fit for producing huge force. They can pulverize turtle shells easily, and an enormous Saltwater Crocodile holding a pig's head can smash the skull by utilizing the muscles from a "standing beginning". However, the muscles that open the jaws have little quality. For instance, an elastic band around the nose of a 2 m long crocodilian is adequate to forestall it opening its mouth. Conversely, two tough individuals outfitted with a collection of switches are needed to constrain open the mouth of a 1 m long crocodilian against the activity of the muscles holding it shut.

Therefore, the correct answer is option (A).

Note: Although crocodilian jaws are equipped for huge force, they are additionally fit for fragile and delicate activity. Huge grown-ups can get and roll unhatched eggs between their jaws, delicately crushing them until they incubate. Most types of crocodilian convey recently incubated youth down to the water in their mouths.
