Crocodiles use defense mechanisms like camouflage and distress calls that alert nearby crocodiles of danger, both of which help protect themselves against predators. Their hard, scaly exterior also provides a protective barrier against attacks, as well as their own aptitude to attack and drown a threat or prey.
A crocodile's ability to blend into its environment not only makes it difficult for predators to spot, but it also positions the crocodile for ambush attacks. When under attack by a large animal, a crocodile will likely latch onto its neck and drag it into the water to drown it. The crocodile may also flip the animal onto its backside to dismember it, as stated by the University of California Museum of Paleontology.
