The Larger The Size, The Scarier
Even though this is obvious, the larger the crocodile, the more aggressive they are. More than likely this is because they’ve survived based on their acquired survival skills (i.e. aggression, territorial domination, etc.) If you see a two-meter crocodile, you can feel a lot safer than if you see a four-meter one. But if you do see one that’s four meters or longer, you better run for your life. This is because, according to experts “a two-meter croc won’t eat a human, but once you get an animal that is four meters long, humans are certainly on the menu. You do have to take precautions in croc habitat” (The Guardian).
