Do you want to know where to see crocodiles in the wild? Not to be confused with its distant cousin the alligator, Crocodiles are large semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. Crocodiles are a living link with the dinosaur-like reptiles of prehistoric times and are the nearest living relatives of the birds. A large variety of crocodilian fossils have been discovered that date back 200 million years to the Late Triassic Epoch.
Types Of Crocodiles
Crocodiles come in 13 distinct species, exhibiting considerable variation in their sizes. The smallest type is the dwarf crocodile, measuring about 5.6 feet (1.7 meters) long and weighing between 13 to 15 pounds (6 to 7 kilograms). Conversely, the largest species is the saltwater crocodile. We have covered the most commonly encountered 8 types of crocodiles.

About
The crocodilian form is adapted to an amphibious way of life. Its body is elongated, and its long, muscular tail is well suited to rapid swimming. They have evolved to be one of the most resilient predators in existence through their highly developed sense; Crocodiles have acute senses, an evolutionary advantage that makes them successful predators. The eyes, ears and nostrils are located on top of the head, allowing the crocodile to lie low in the water, almost totally submerged and hidden from prey.
Crocodile Teeth
Crocodiles can go through 4,000 teeth over a lifetime. They are able to replace each of their 80 teeth up to 50 times over their lifespan.
Distribution & Habitat
Crocodiles, sizable reptiles, dwell within the tropical regions of the Americas, Australia, Africa, and Asia. They are not naturally found in Europe, making it the sole continent where they do not inhabit. Crocodiles are inhabitants of swamps, lakes, and rivers, although some species make their way to brackish water or to the sea.
Behavior
Some species of crocodiles are active during the day, while others are nocturnal. They mainly hunt at night, relying on their carnivorous nature and superior senses of hearing and eyesight. Crocodiles are aggressive ambush predators, patiently waiting for their prey to approach before swiftly attacking.
Diet
A crocs diet mostly includes other animals, reptiles, birds and fish. Some species like the freshwater crocodile will mostly eat fish, while larger species like the saltwater crocodile or the Nile crocodile, will consume buffalo, zebra, deer and wild boar.
Breeding and Lifespan
The timing of the breeding season differs depending on the crocodile species and their geographical whereabouts. Freshwater crocodiles typically breed in the dry season, which falls around mid-summer in the southern hemisphere and mid-winter in the northern hemisphere. In contrast, saltwater crocodiles tend to breed during the opposing wet season. All crocodiles lay hard-shelled eggs, which may weigh 50–160 grams. Crocodiles in captivity are known to have lived up to 70 years. The longevity of crocodiles in the wild is poorly known.
Crocodile Speed, Intelligence, and Communication
Crocodiles are extremely fast in the water, swimming up to speeds of 35 kilometers per hour (22 mph). The land speed record for a crocodile is 17 km/h (11 mph) measured in a galloping Australian freshwater crocodile. Crocodiles vocalize to communicate. The young of some species squeak and grunt, while adult crocs can growl, hiss or roar at each other. Crocodiles are capable of complex behaviors. They are often curious and show evidence of rapid learning. Captive individuals of some species are known to recognize their keepers and show neither fear nor aggressiveness. They can observe and use patterns of prey behavior, such as when prey come to the river to drink at the same time each day.
Conservation
Throughout their range, crocodile populations have declined as human occupation and land use change has reduced their habitat. Many crocodilian species have been greatly depleted by overhunting for their valuable skins—which provide leather for handbags, shoes, belts, and other articles. Sustainable harvesting, regulated trade, and education have become valuable components of crocodilian conservation.
How Old Are Crocodiles?
Crocodiles have evolved over 200 million years but the species first appeared 95 million years ago in the Late Cretaceous period. They are the closest living relatives of birds; the two groups are the only known survivors of the Archosauria.
Difference Between Crocodiles and Alligators
To most people, alligators and crocodiles look similar. While they do share many of the same features, they couldn’t be any more different to a trained professional. Typically, crocodiles are more aggressive than alligators, which makes crocodiles more dangerous than alligators. Alligators are opportunistic feeders. They do not hunt unless it is necessary. However, that certainly doesn’t mean that you should swim with them. Caution should be exercised at all times near alligators and crocodiles. Alligators have a wide, rounded, u-shaped snout, while crocodiles have long, pointed, v-shaped snouts. Crocodiles are different from alligators in this sense, where both upper and lower jaws of a crocodile are the same size, exposing their teeth as they interlock, creating the look of a toothy grin.
Is it Safe to See Crocodiles?
The larger species of crocodiles are very dangerous to humans, mainly because of their ability to strike before the person can react. The saltwater crocodile and Nile crocodile are the most dangerous, killing hundreds of people each year in parts of Southeast Asia and Africa. Always keep a watch for crocodiles. They will see you before you see them. Never provoke, harass or interfere with crocodiles, even small ones. Never feed crocodiles — it is illegal and dangerous. even in areas where proactive crocodile management is well-established, ultimate responsibility for your safety lies with you.

Summary
These prehistoric reptiles are a privilege to witness in the wild. Importantly, safety is foremost the biggest concern, and it is up to the tour guide and tourist to be as informed of protocols as possible. Many thrilling and educational tours exist to keep viewers amazed at a safe distance. Likewise, for their relatives the alligators, there are many tours offered. In a while crocodile!
As a little kid, I fell in love with nature, wildlife, and animals. Living in the USA, South Africa, Italy, China and Germany gave me the opportunity to discover the world's Wildlife. My favorite animals are Mountain Gorillas, Siberian Tigers, and Great White Sharks.
I'm a certified PADI Open Water Diver, went to Everest Base Camp and Trekked Gorillas in Uganda. I hold a Master of Science in Economics and Finance.
