Alligator vs. Crocodile
One sees you later, the other in a while. Another difference: Alligators have wide U-shaped snouts, and crocodiles tend to have more pointed V-shaped snouts. Alligators’ upper jaws are wider than their lower jaws, so when their mouths are closed, the teeth in the upper jaws are visible, while the teeth in the lower jaws are not. Conversely, crocodiles’ upper and lower jaws are about the same width, so when the mouth is closed, several lower teeth are visible. There are only two existing alligator species, the American alligator, native to the southeastern United States, and the endangered Chinese alligator, native only to the Yangtze River. There are 23 existing species of crocodile, and they’re found in tropical waters in Africa, Asia, the Americas, and Australia. Can you spot the camouflaged animals hidden in these photos?
Frog vs. Toad
All toads are frogs, but not all frogs are toads. Both are species of amphibians. Frogs spend their lives close to water, but toads are able to venture farther onto dry land. Toads are often brown and have dry, bumpy skin. Frogs are mainly green and are wetter and smoother to the touch. Frogs have teeth; toads don’t.
