The crocodile attains a length between 6. The crocodiles are known for their aggressive nature and are potentially dangerous to humans. The Cuban crocodile lives in freshwater marshes and rivers and is the most terrestrial of all the extant crocodile species. The reptiles feed on turtles, small mammals, and fish. Like many other crocodilians, the Cuban crocodile is also listed as a Critically Endangered species.
Today, the range of this species is limited to the Isle of Youth and the Zapata Swamp of Cuba although its historic range was spread across the Caribbean. Hunting has been the biggest factor in reducing the numbers of this species to dangerous levels.
The saltwater crocodile Crocodylus porosus or the estuarine or marine crocodile is the most dangerous crocodilian living today. Males grow as long as The saltwater crocodile is true to its name and can survive in marine environments. However, it is usually found in brackish and saline habitat like deltas, mangrove swamps, lagoons, and estuaries. This type of crocodile also has the widest range of other species of crocodiles and is found throughout the Indian subcontinent, Australia, and Southeast Asia.
The saltwater crocodile drowns and swallows its prey as a whole and is a hypercarnivorous predator that can overpower almost any animal in its territory. These crocodiles and known to kill and consume even humans.
The mugger crocodile Crocodylus palustris is called by various names like the Indian, marsh, Persian crocodile or even just mugger. The mugger, the national reptile of Pakistan, is found throughout the Indian sub-continent.
It is medium sized and is observed living in freshwater swamps, marshes, lakes, and rivers. The muggers attain lengths of 13 to 16 feet and has the broadest snout of any living crocodile species. The crocodiles are heavily armored with enlarged scutes around the neck.
The mugger is an apex predator in its habitat. It is an ambush hunter that waits for its prey to arrive and then suddenly attacks the prey. The muggers, despite their strong predatory skills, are not usually aggressive by nature and pose a lesser threat to humans than the saltwater crocodiles.
The American crocodile inhabits brackish or saltwater areas and can be found in ponds, coves, and creeks in mangrove swamps. American crocodiles occur in South Florida and also can be found in Hispaniola, Cuba, Jamaica, along the Caribbean coast from southern Mexico to Venezuela, and along the Pacific coast from Mexico to Peru.
Occasionally, crocodiles are encountered inland in freshwater areas along the southern Florida coast Distribution map data from: Krysko et al. Like alligators, crocodiles are ectothermic, meaning they rely on external sources of heat to regulate their body temperature. Crocodiles control their body temperature by basking in the sun, or moving to areas with warmer or cooler air or water temperatures.
A basking crocodile may be surprised by an approaching person and quickly and noisily enter the water. This behavior might startle the person, but it should not be misunderstood. Crocodiles would normally enter the water quietly; splashing away indicates that the crocodile is frightened. Crocodiles can also be seen sunning with their mouths open, or "gaping. The diet of the American crocodiles primarily consists of small mammals, birds, frogs, turtles, and fish Fishman et al.
Male crocodiles begin courting females in late January and early February. Crocodiles are ectothermic and therefore control their body temperature by basking in the sun, or moving to areas with warmer or cooler air or water temperatures. Courting rituals can be extensive, often lasting for days. Males initiate courting by quickly and consecutively performing head slaps, and the female will raise her snout and arch her tail if she is interested.

Crocs can hold their breath underwater for more than an hour. But don't be fooled by their seeming lack of activity—crocs can swim up to 20 miles per hour 32 kilometers per hour and can run on land as fast as 11 miles per hour Some species are active during the day while other species are nocturnal.
Most crocs prefer to stay in water and can look clumsy on land, coming ashore only to bask on sandbars and river banks or to lay eggs. Yet in the water they are agile swimmers, moving with ease by using their powerful, oar-like tails and strongly webbed hind feet. Many croc species hibernate or go dormant during colder months or long periods of drought, in burrows dug in the sides of river banks. Supper time! Crocs are carnivores and eat whatever they can catch in the water or along the shore.
That includes fish, turtles, frogs, birds, pigs, deer, buffalo, and monkeys, depending on the size of the croc. Gharials and false gharials are specialists, though—with their slender snouts, they tend to stick to eating fish.
Gharials have about slender, very sharp teeth. They hunt near the river bottom, slowly moving about and then making swift sideswipes, snapping up fish that come too close to their jaws. Crocs don't chew their food. They either tear off large pieces and swallow them or swallow the prey whole if it's small enough. The croc has to juggle the food around until it's in the right position, and then toss its head back so the food slides down its throat.
Crocodilians can survive months between meals. When hungry, however, some croc species can eat up to half their body weight in one meal. Male crocs are territorial and may fend off other males from his group of females. Male gharials can produce buzzing and whistling noises through the bulb on the tip of their nose to attract females—a crocodilian whistle of appreciation. Mama crocs. For such ancient, ferocious-looking animals, crocodilian moms take really good care of their hatchlings!
Crocs are one of the few reptiles that watch out for and protect their young until they are old enough to be on their own. The cow female croc looks for just the right place to build a nest to lay her eggs.
Some species make a mound nest out of soil and vegetable material; others dig a hole in the sandy beach for their nest. The mama croc then settles in nearby to guard the eggs from predators—large birds, lizards, mongooses, or even raccoons—that might try to dig them up and eat them. Some croc moms even help their baby by gently biting the egg to open it up more easily.
After the young have hatched, the mother carries them to the water in her mouth and then guards them for most of the first year of their lives. She threatens or attacks any predator that lurks too close; mothers of some species call the hatchlings to swim into her mouth for protection—making it look like the youngsters have been swallowed!
The exception to this parenting style is the gharial, which has a mouth that is too narrow to pick up her young.
