Crocodile jaws

They are called carnivores because they eat other animals as food.  They do not eat any vegetables or herbaceous plants except meat.  Normally a crocodile can live up to 35-75 years old, you will be surprised to know that they grow 4000 teeth in their lifetime.  But their jaws have 60-110 teeth.  There are certain teeth which are always fixed and always do some important work.  All those teeth are in standby mode anyway.  However, small teeth fall out after a certain period of time.  In this way, their teeth fall out and grow again about 50 times in their entire life.
