The mouth of crocodile depends on the size of the crocodile. Large crocodiles tend to have huge mouths that can easily engulf the head of a man. On the other hand, the dwarf crocodile is about 5.5 feet and has a small mouth.
Crocodiles do not chew their prey. They swallow it whole if the prey is small, and when the prey is large, they tear it apart. The saltwater crocodiles of Australia are some of the largest in the world, with an average length of 13 to 15 feet. They weigh almost 2,000 pounds and have very large mouths with razor-sharp teeth.
