SIGNAL WORDS NG
Alligators and crocodiles, along
with their relatives the caimans
and the gavials, are very much
alike. These crocodilians are
reptiles with long snouts, long
tails, four short legs, tough skin,
and sharp teeth. There are some
differences, however. Gavials
have the longest snout and the
most teeth. Some people say that
alligators and crocodiles differ in
the shape of their snouts and the
positioning of their teeth.
Zookeepers say that crocodiles
move faster than alligators and
have nastier dispositions.
