Crocodiles have a streamlined body which enables them to swim really fast. Another feature of crocodiles which help them to swim speedily is that they tuck their feet to their sides while swimming. By this water resistance is reduced and enables them to swim faster.
In water as well as out of water, crocodiles are very fast over little distances. Crocodiles grab and hold onto their prey while eating. They have developed sharp teeth for holding on to the prey and tearing flesh. Their jaws have powerful mussels that close the jaws and hold them shut. However their jaws are opened by a very weak set of mussels.Crocodiles can be transported or subdued for study very simply because of these weak mussels. They could be handled by taping their jaws or holding the jaws together by large rubber bands cut out of automobile inner tubes.
Their teeth are sharp-pointed, inter-locking and are perpetually replaced. A single croc might grow up to 3,000 teeth in its lifetime. How amazing is that? A small bird hops right into the prehistoric estuarine Crocodile's mouth and clean its teeth.
Stay away from infested waters. This is the simplest way to avoid a crocodile attack. Ask local authorities or residents about the presence of crocodiles in lakes and rivers in your area and don't go swimming outside the designated swimming areas. These animals actively hunt at night when they are hardest to see, so avoid swimming at dusk or at night.
