Alligators and crocodiles are both known for living in or near water, but alligators are freshwater animals and crocodiles live in saltwater. Their behavior regarding water is very similar. During the day and at night, both crocodiles and alligators are active in the wetlands and on the coast.
Alligators have been known to swim in the water to escape predators. They have also been observed swimming in shallow water. In addition, they can be found in swamps, marshes, rivers, lakes, ponds, creeks and other bodies of water throughout the United States.

Are alligators and crocs genetically related?
Ray said alligators’ and crocodiles’ genetic structure is 93 percent similar. He said that the pair looked very much alike after they diverged from the evolutionary trail about 90 million years ago. “They’re very similar to each other,” Ray told Live Science in an email. “They have a lot of the same genes, and they share a common ancestor with crocodilians.” Alligators and crocodylians are both reptiles.
Alligators are the largest land-dwelling reptile in the world, with a body length of up to 4 feet (1.2 meters) and a tail that can grow to more than 10 feet long (3 meters). They are found in tropical and subtropical regions around the globe, including the United States, Mexico, Central and South America, Australia, New Zealand, South Africa, the Caribbean and the Pacific Islands.
What animal is similar to a crocodile?
The family of reptiles includes Alligators, Crocodiles, Caimans, and Crocodylomorphs. The largest alligator ever caught was a 10-foot-long (3.5-meter) specimen caught off the coast of Florida in 1995. Alligator meat is considered a delicacy in parts of Africa and Asia.
What is the difference between alligator and crocodile skin?
Alligator skin has smaller scales that are smoother than a crocodile’s. The scales are larger in the middle and smaller as they move outside. The tile pattern in a crocodile is symmetrical and rectangular.
The skin of an alligator is thick and tough, but it is not as tough as that of crocodiles. Alligators have a thick layer of fat on their skin, which helps keep them warm. Their skin is also covered in scales, giving them a more reptilian appearance.
Can crocodiles and alligators mate?
Owlcation, crocodiles and alligators are not related enough to be considered the same species. “Alligators are the most closely related of all reptiles to crocodilians,” the site explains. “Alligator and crocodylians share a common ancestor that lived in the Cretaceous period, about 65 million years ago.
Crocodilia, on the other hand, evolved from alligator-like reptiles, which lived during the Triassic period (about 65 to 65.5 million) and the Jurassic Period (65 to 66 million).
Which is bigger crocodile or alligator?
Crocodiles are the larger species and fully-grown will be up to a metre longer than even large alligators. They have long, v-shaped snouts and are a lighter colour. crocodiles have a toothy grin because of this v-shaped snout. crocodiles can\’t close their snouts to hide their teeth, which is why they are referred to as “grizzly bears”.
The crocodile is also known as the ‘king of the jungle’ because of its ability to live in almost any environment. It is found in tropical, subtropical and temperate regions of Africa, Asia, Australia, South America, Europe and North America. The largest crocodilian species is the African Crocodylus acutorostratus which can reach a length of over 2.5 metres (8 feet) and weigh over 1,000 kilograms (2,500 pounds). .
Do alligators and crocodiles share DNA?
Scientists can better understand birds if they understand the crocodilian genome. DNA in alligators, crocodiles and gharials is about 93 percent identical to that found in birds, according to a study published last year in the journal Genome Biology and Evolution.
“This is the first time that we’ve been able to sequence the entire genome of a reptile,” said study co-author Dr. David Reich, director of the Center for Comparative Genomics at the University of California, San Diego.
