Crocodile vs. Alligator

The Snout Test

If you spot a giant, armored reptile lounging on a muddy riverbank, you might struggle to name it. While they look like twin monsters from the age of the dinosaurs, crocodiles and alligators are very different creatures.

The easiest way to tell them apart is to look them right in the face. Alligators have wide, U-shaped snouts like a shovel. This shape is perfect for crushing hard-shelled prey like turtles. Crocodiles have narrower, V-shaped snouts built for snatching quick fish and mammals.

Next, check out their teeth. When an alligator closes its mouth, its upper teeth fit neatly over its lower jaw, hiding them from view. A crocodile has a messy, snaggle-toothed grin. Its lower jaw is narrower than its upper jaw, meaning that when its mouth is clamped shut, a massive fourth tooth on the bottom jaw sticks straight up over its upper lip.

Built-In Desalination Plants

Their internal biology also sets them apart. Crocodiles have active salt glands (organs that filter salt out of the body) on their tongues. This biological filtration system lets them live in saltwater habitats like oceans and mangrove swamps. Alligators have these glands too, but they do not work. This limits gators to freshwater environments like lakes, rivers, and golf course ponds.

Their skin color matches these habitats. Alligators are dark gray or black, which helps them blend into murky, muddy freshwater. Crocodiles are lighter, sporting olive, tan, or grayish-green skin that camouflages them in sunny, salty coastal waters.

Timid Gators vs. Short-Tempered Crocs

If you ever encounter one, their behavior is the ultimate difference. Alligators are generally timid and prefer to swim away if humans get close. Crocodiles have a notoriously short fuse. They are highly aggressive and much quicker to strike.

Both reptiles are top-tier predators, but the crocodile wins the strength contest. A large saltwater crocodile can slam its jaws shut with 3,700 pounds of force. That is three times stronger than the bite of a grizzly bear, easily crushing bones and armor alike.” and armor alike.”
