Crocodiles can swim at 25mph just with the help of their powerful tail. Farmed crocodiles can reach 1.5 metres (5ft) in length in just one year. When crocodiles sit on river banks with their mouths opens, it's not aggression. They're trying to cool off as they sweat through their mouths. Crocodiles display increased aggressiveness during the mating season, which is linked to the monsoon. Each crocodile jaw has 24 teeth that are meant to grasp and crush, not chew. They swallow stones that grind food inside their stomachs, and also act as ballast. Find this video where a fight between crocodile and snake is featured.
