Nile crocodiles are apex predators and their clever usage of tools to capture prey has significant implications. This tactic presents an added challenge for prey species, influencing their population dynamics.

Crocodiles are ambush predators, relying on stealth and patience to catch their prey. They often lie motionless in the water, waiting for an unsuspecting animal to come close before launching a lightning-fast attack.

They are agile predators and wait for the opportunity for a prey item to come well within attack range. Even swift prey are not immune to attack. Like other crocodiles, Nile crocodiles have a powerful bite that is unique among all animals, and sharp, conical teeth that sink into flesh, allowing a grip that is almost impossible to loosen.

Nile crocodiles have long and powerful jaws, which perfectly fit catching and holding the prey. Due to a special valve, found at the back of their throat, these crocodiles can move underwater with an open mouth, and grab and hold prey without ingesting water. Nile crocodiles are grey-olive in color and have yellowish bellies.

Nile crocodiles are aggressive when they are encroached upon and have the strongest tendencies to treat humans as prey. They are estimated to kill hundreds of humans each year, which is more than any other crocodile species including the larger saltwater crocodile.
