Which statement best describes a distinguishing feature of the Nile crocodile?

• A. Venomous bite.
• B. Excellent swimming ability and spends most of its time in freshwater.
• C. Lives in saltwater environments.
• D. Primarily terrestrial hunter.

Answer: (B)

The main idea here is that Nile crocodiles are highly adapted to a life spent in water, especially in freshwater habitats. They are superb swimmers—their powerful tail propels them with great speed and efficiency—so they spend the vast majority of their time in rivers, lakes, and floodplains. This combination of excellent swimming ability and a strong preference for freshwater environments is what clearly distinguishes them. Venomous bite is a common misconception; crocodilians don’t have venom that they inject with a bite. Saltwater environments aren’t the hallmark of the Nile crocodile, which can tolerate brackish waters but is not primarily a saltwater species. And they aren’t mainly terrestrial hunters; they rely on ambushing prey from the water, so their hunting is tied to their aquatic lifestyle.
