Crocodilians are large, lizard-shaped reptiles with four, short legs and a long, muscular tail. They have a rough and scaled hide. Once you get the hang of distinguishing between the two, it’s easy to spot the difference between alligators and crocodiles. The most common species of crocodile in the United States is the alligator.
Alligators can be found in all parts of the country, but they are most commonly found along the Gulf Coast and in Florida, Louisiana, Mississippi, Alabama, Arkansas, Tennessee, and Kentucky. They are also found as far north as Canada and south to Mexico and Central America.

Is lizard same as crocodile?
Although saltwater crocodiles and monitor lizards do share certain similarities, these creatures are special in their own ways and exhibit very different characteristics and traits. When you see something moving in these animals’ habitat, look for their body shape, size, and color. Saltwater crocodylians are the largest reptiles on the planet. They can grow up to 6 feet in length and weigh as much as 2,000 pounds.
This is a huge difference from the monitor lizard, which can only grow to about 1.5 feet long and weighs less than 100 pounds, according to the National Oceanic and Atmospheric Administration’s (NOAA) National Marine Fisheries Service (NMFS). The difference in size can be attributed to a number of factors, including the amount of salt water they are exposed to, as well as the size of their stomachs.
In fact, the salt content of a crocodile’s stomach can determine how big it is. For example, if the stomach is full of water, it will be much larger than if it was empty.
Are crocodiles reptiles or lizards?
Reptiles are turtles, snakes, lizards, alligators and crocodiles. Unlike salamanders, reptiles have dry, flaky skin that prevents them from drying out. Reptiles can live for hundreds of years. Their venom is powerful enough to kill an adult human in a matter of minutes. The venom can also cause paralysis and death if it is injected into the bloodstream.
Is a crocodile part of the lizard family?
Crocodiles are members of the Reptilia taxonomic class with other creepy crawlers, including snakes and lizards. Birds are also lumped in that group according to paleontologists. “The crocodile is a member of a group of reptiles that includes alligators, crocodiles, caimans, and alligator-like reptiles,” said study co-author and University of Texas at Austin professor of geology and geophysics David Evans, in a statement.
“It is the only reptile that has been found in the fossil record from the Cretaceous period, which began about 65 million years ago.” The fossilized remains of Crocodylus aegyptiacus, a crocodilian that lived in Africa.
Crocodiles have been around for a long time, but it wasn’t until the mid-20th century that scientists began to realize that crocodilians were actually a distinct group, Evans told Live Science in an email. That’s when he and his colleagues began studying the fossils of crocs and other reptiles in order to better understand the evolution of these animals, .
Why are crocodiles not considered lizards?
Crocodile scales don’t overlap while a lizard’s does, their hearts are different, crocodiles have a secondary palate, and lizards have a second set of teeth. Well, they’re both reptiles, but iguanas are more closely related to humans than to other reptiles.
That’s because they share a common ancestor with humans, which means they have the same genes that make up the human genome. So, if you’re a human and you’ve got a reptile in your family tree, you’ll be able to tell them apart just by looking at them.
Are crocodiles just big lizards?
No, crocodiles are not lizards. Although crocodiles and lizards have the same body shape, they are not related. Crocodilian order includes crocodiles, alligators, and caymans. Diprotodontia has lizards on the other side.
Is Komodo dragon a lizard?
Komodo dragon is the largest living lizard in the world. The largest verified specimen of a wild dragon reached a length of over 10 feet and weighed more than 300 pounds. Males are larger and bulkier than females. Komodo dragons live in tropical and subtropical rainforests in Indonesia, Papua New Guinea, Borneo, Sumatra, and the Philippines.
Why are lizards and crocodiles kept in the same category?
Lizards and crocodiles are kept in the same category because they are cold-blooded. A lizard is a reptile that lives in water, while a croc is an animal that can live on land. Some of the most common species are: loricariids (crocodiles), piscivores (mammals), and cetaceans (whales, dolphins, and porpoises). arthropods (such as insects and arachnids), mollusks, cephalopods, fish, amphibians, reptiles, birds, mammals, etc.
