American Crocodile - The Life of a Ferocious Predator

The endangered American crocodile can be identified by its snout, which is longer and narrower than that of the American alligator.
The crocodile is one of the Earth's oldest living species and is one of the few remaining animals that link us to the time of the dinosaurs. Is the American crocodile aggressive? Yes the animal can do some damage and bite or even kill when sufficiently annoyed. For the most part, however, the American crocodile lives in protected areas where they can breed and exist unmolested by human beings.

Why are American Crocodiles confused with American Alligators?

As both types of animals often share a habitat such as the American crocodile habitat in South-Florida, the two animals are often confused. American crocodile information shows that alligator adults are actually dark gray or black while crocodiles are lighter. The snout configuration is also a tell-tale difference. The crocodiles always have a longer, narrower snout with the end of the alligator snout appearing somewhat shovel-like.

The Range and Population Level of American Crocodiles

The crocodile is known to live along the east coast of North America. Although it appears this environment is suitable for the crocodiles to breed, their numbers in Florida continue to decline with the current population of 300-400 animals including only 20-30 breeding females. Scientists are divided on the reasons behind this decline but conjecture that the crocodile may not breed well in proximity to human habitation.

Where can the American Crocodile be found?

American crocodiles live in the state of Florida, along the Mexican coastline, and in the still waters of Central American rivers. In Florida they are primarily located in the vast Everglades although they will venture into closer proximity to cities and towns. Consequently, Florida residents have learned to be vigilant about the presence of both crocodiles and alligators.

The Features of the American Crocodile

The following features may help to identify the endangered American crocodile:

The American crocodile are usually light gray-green or olive green and they have long and slender snouts compared to those of alligators that are rounder and wider. The snout of the American croc tapers forward.

An American crocodile hatchling (a crocodile that just came out of its egg) is about 25 cm long. An adult crocodile can be approximately 4.5 meters long. (Some males can be even longer.)

American crocodiles lachrymal glands positioned close to the eyes. These glands help the animal to clean its eyes with tears, washing out any sand if needed.

American crocodiles have a four-chambered heart like most birds. (Birds and crocodiles share the same evolutionary ancestor.) The four-chamber heart has two different functions; pumping blood around the body and pumping blood straight to the lungs. Because of this the crocodile can spend a longer time under water and the heart provides enough blood flow to enable the body to dive when needed. The animal is able to fully control these functions unlike other animals.
