According to Paw Nation, crocodiles have powerful tails that they use to lash any attackers that cross their paths. They also protect themselves with loud, vocal cries while their tough hide provides an evolutionary defensive mechanism, states the Museum of Zoology at the University of Michigan.
However, Animal Spot adds that crocodiles are apex predators. Since they are stronger than other animals in their habitat, humans are their only real threat. The San Diego Zoo Global Library explains that to fend off danger, young crocodiles also protect themselves by diving into the water upon hearing their mother’s vibrating muscles around her rib cage.
