Baby alligator (note the tiny teeth), Arthur R Marshall Loxahatchee National Wildlife Refuge, FL. Alligators have no molars, so they cannot chew their food. They feed by swallowing prey whole or tearing off a chunk they can swallow.
A recent Florida State University study found that mature American alligators exert twice the bite force that enables a wolf to crack an elk leg bone. And while mammals will not bite with full force if it might injure their teeth (Cats, for example, have proprioceptive sense in their canines to tell them when they are biting between vertebra.), alligators like sharks are replacing teeth all the time. They always bite with maximum force.
