Crocodiles-Alligators



Beauty Of Animal | Crocodiles-Alligators | Alligators and crocodiles have been considered villainous, man-eating monsters for centuries, but that wasn't always the case. In ancient Egypt, crocodiles were revered and even worshiped, but that worship was tinged with a deep-seated respect for this powerful, awesome creature. Myths sprouted up around these impressive beasts from the earliest time of man, and some persist today. Part of this is due to the fact that crocodiles and alligators have truly ancient roots, going all the way back to the period when dinosaurs still roamed the earth.


The two are often confused, but visually crocs and alligators are quite different. Alligators have a very broad, wide snout, and crocodiles have a narrower snout and jaw. Also crocodiles often have a lower tooth that juts out noticeably, while an alligator's fourth tooth is hidden. WHERE THEY LIVEC rocodilians are a cold-blooded species, and require an average temperature of approximately 80 degrees Fahrenheit to survive. This being the case, they are found on warmer continents that have swampy or humid conditions for at least part of the season.


The American alligator lives almost exclusively in the lower southeast regions of North America, from the Carolinas to Texas. The caiman, a smaller species of crocodiles, populate a large section of southern Mexico, Central and South America. The Chinese alligator lives in the lower Yangtze valley in China. The American crocodile is scattered throughout the Everglades and Florida Keys, and in Mexico and Central America. The African Nile crocodile is one of the most notorious, often growing as large as 16 to 20 feet in length. Southeast Asia has the Indo-Pacific crocodile, which lives in Indonesia, to the Philippines, and Australia.
