Did you know that some crocodiles haven't evolved since the time of the dinosaurs? This isn't a sign of their antiquity; it's proof that a crocodile is so superior at what it does it doesn't
need to. What it does is pretty self-explanatory; it kills things.
Dwelling in the tropics of Tropics Africa, Asia, the Americas and Australia crocs usually mass in slow moving rivers and lakes. They feed on living and mammals and fish. Yeah tasty. But the croc daddy has to be the saltwater crocodile.
The saltwater is capable of swimming out to sea and is of the most ancient lineage of all. They hunt large creatures such as buffalo but they can also take wildcats, sharks and careless humans with ease. It isn't a constantly active predator, prefering to loiter in the water or bask in the sun through much of the day, typically preferring to hunt at night. When required, however, it is capable of moving with astonishing speed when required, able to cover 10m from a standing start significantly faster than a race horse. It is especially fast from the edge of the water, where both legs and tail are used for propulsion. As an ambush predator, it usually waits for its prey to get close to the water's edge before striking without warning and using its great strength to drag the animal back into the water where it is usually drowned. It is an immensely powerful animal, having the strength to break a large animal's legs with its tail, drag an water buffalo into a river, or crush an animal's skull between its jaws. Its jaws have over two tons of crushing power.
If that's not scary I don't know what is.
