What is the Difference Between Caiman and Alligator?

🆚 Go to Comparative Table 🆚

The main differences between caimans and alligators are found in their appearance, size, and habitat. Both caimans and alligators belong to the family Alligatoridae and share similar characteristics, but they also have distinct features. Here are the key differences between caimans and alligators:

  1. Teeth: Alligators have round, short, and wide teeth, while caimans have long and narrow teeth. The alligator has a little overbite, and its mouth is beige, while the caiman has a large upper jaw and an orange tint to its mouth.
  2. Snout: Alligators and caimans both have a rounded, U-shaped snout and tend to have an overbite, while crocodiles have a V-shaped snout and no overbite. Caimans have rougher scales on their belly and back, and more scales on their head compared to alligators.
  3. Size: Most caimans grow to four to five feet long, but black caimans can grow up to twelve feet in the wild, which is similar to the size of alligators. Alligators are generally larger than caimans, with the average male alligator measuring 11.2 feet.
  4. Habitat: Caimans are native to South and Central America, as well as some parts of North America, while alligators are found mostly in the southeastern United States, South Africa, and China. The Everglades is the only place where crocodiles and alligators coexist.
  5. Agility: Caimans tend to be more agile and crocodile-like in their movements than alligators.

It is easy to confuse caimans and small alligators due to their similar appearance, but these differences can help distinguish between the two species.

Comparative Table: Caiman vs Alligator

Here is a table summarizing the differences between caimans and alligators:

Feature Caimans Alligators
Snout Shape Somewhere in between the snouts of alligators and crocodiles, with a more pointed snout than an alligator but not as narrow as a crocodile's Broad, rounded snout
Size Most caimans only grow to 4 to 5 feet long, but Black caimans can grow up to 12 feet in the wild American alligators grow between 8 and 12 feet (some individuals reach 13 feet)
Distribution Not native to the United States, found in Central and South America Native to the United States, found in various freshwater habitats, such as swamps, lakes, and rivers
Scales Typically have rougher scales on the belly and on their back, with more scales on a caiman's head Have rounded teeth and are generally larger than caimans
Taxonomy Part of the same family (Alligatoridae) as alligators, but split into a separate subfamily Caimaninae, containing six species in three genera Part of the same family (Alligatoridae) as caimans, with two species of alligator

Both caimans and alligators are closely related and share many similarities, such as being darker in color and having sharp teeth. However, the most significant differences between the species are their distribution, snout shape, and size.
