Crocodilians Quiz – Ancient River Hunters

Crocodilians include crocodiles, alligators, caimans and gharials, about 26 species in all. Their ancestors lived alongside the dinosaurs, and modern crocodilians have changed relatively little in tens of millions of years.

They are ambush predators, waiting in water with only their eyes and nostrils showing. Saltwater crocodiles have the strongest bite ever measured, while gharials use slender snouts to catch fish. Despite their fierce reputation, they are caring parents.

Many crocodilians were hunted for their skins, pushing species like the American alligator to the edge. Protection helped alligators recover strongly, but gharials and Chinese alligators remain critically endangered because of habitat loss.
