The Alligator referred colloquially as gator are amazing animals that have been around for millions of years. Alligators are in the same family as other large reptiles like crocodile but are native to only two countries, which are the southern USA and China. The American alligator are found in the South-eastern USA, throughout all of Florida and Louisiana, the southern parts of Georgia, Alabama and Mississippi, coastal south and North Carolina, eastern Texas, the south-eastern corner of Oklahoma and Arkansas.
Alligator is a solitary predator that is actually surprisingly clunky when moving about on land. They tend to be quite slow, moving themselves by either crawling or sliding along the slippery banks on their bellies.
Alligator are known to be highly territorial animals that make a variety of noises to represent different things, including the declaration of territory, finding a mate and the young warning their mother that they are in danger. An alligator is an apex predator in its environment, known to even hunt animals that are much larger in size.
There are two extant species of alligators that is, the Chinese alligator (Alligator Sinesis) and the American Alligator (Alligator Mississippiensis).

Crocodiles are large semi-aquatic reptiles that live throughout the tropics in Africa, Asia, the America and Australia. Crocodiles are highly carnivorous and formidable predators at the top of the food chain in their natural environments. They are members of the order Crocodilia, which also includes Caimans, Gharials and alligator. Today, there are 13 different crocodile species that are found inhabiting both fresh and saltwater environments throughout the world. Their Semi-aquatic nature has led to them evolving a number of key adaptations that allow them to survive so successfully in their natural environments.
Crocodile’s powerful bodies, strong jaws and immense speed and agility along with their unparalleled stealth, has resulted to them being one of the world’ most apex predators in their natural environments. Crocodiles have scaly skin that is made up of armoured, waterproof plates that booth protects them from potential predators and also prevents their bodies from drying out. These scales come in a variety of colors from dull olive and green, to brown, grey and black meaning that they are very easily camouflaged in the surrounding water and vegetation.
Just like other reptiles, crocodiles are not able to regulate their body temperature themselves and instead rely heavily on the heat of the sun to warm up their enormous bodies. During the hot daytime hours, they bask in the sun on the riverbanks warming their bodies up from a night of hunting.
What You Need To Know About Alligator
- Other than Europe and Antarctica, Crocodiles are found almost everywhere around the world. The largest populations of crocodiles can be found in Central Africa (Nile crocodile) and Asia (Borneo, saltwater crocodile).
- Crocodiles snouts are long, narrow and pointed in other words the snouts are V-shaped.
- Crocodiles appear light brown, green or gray.
- The largest crocodile species (saltwater crocodiles) can weigh averagely 2000 pounds.
- They are larger in length than alligators. They can grow up to 6.2 meters.
- The smallest species of crocodile (dwarf crocodiles) can measure about 5.5 feet in length and weigh about 14 to 20 pounds.
- The average lifespan of a crocodile is between 70-100 years.
- Crocodiles can live in both freshwater and saltwater habitats. Their adaptability makes them more likely to be found throughout the world. Crocodiles have evolved special glands on their tongues which help them excrete excess salt from their bodies.
- Crocodiles eat frogs, birds, fish, gazelles, crustaceans (crab) and large mammals (wildebeest and zebras).
- Crocodiles don’t begin mating until the summer months (July-August).
- Crocodiles lay an average of 10-60 eggs per batch.
- The extinction threat facing alligators is climate change. Climate change threatens the freshwater habitats of alligators as the rise in sea levels can contaminate fresh water sources with salt water.
- Crocodiles are much more bad-tempered and far more likely to attack humans, even unprovoked.
- Crocodiles have a bite pressure of about 3700 pounds per square inch. Therefore, in terms of aggression, crocodiles will win any fight against alligator.
- The crocodile’s lower teeth are predominantly visible. This means that crocodiles have several teeth sticking above their lips which give them a very jagged smile.

- At any given time an average mature crocodile can have upto 68 teeth.
- Sex of the hatchlings is dependent on the average temperature at certain times during egg incubation.
