Facts about crocodiles

Crocodiles are found in tropical regions of America, Asia, Australia, and Africa. They live in these tropical regions because of their cold-blooded nature. They are aquatic reptiles and they live in a variety of environments such as rivers, freshwater, lakes, saltwater, and other wetlands. They can be in weight from 800 pounds (400 kg) to 2200 pounds (1000kg) and estimated to be 13.1 feet (4.1m) to 17.06 feet (5.2 m) in length.

The largest crocodile is found to be 20.24 feet and 2000 pounds (907 kg) in weight. It is found that there are 13 species of crocodiles in many different sizes. 100 years ago, crocodiles were on the top of the supply chain and but this has decreased over time.

Crocodiles are considered to be carnivorous, as they eat only meat. When they catch their prey they use their jaws to crush them. Its bite is known to be the strongest of any other animal in the world and the teeth are a quick replacement for its previously lost teeth, goes 8000 teeth over time. But instead of chewing the prey into pieces, they swallow them as a whole because the crocodile’s teeth are only designed for grabbing. And so it does a death roll to disable, dismantle and kill the prey. Their jaws are really strong and crocodiles apply high pressure when biting which is 5000 pounds per square inch.

They eat fish, rats, frogs, birds and even locusts and they consume small stones for their digestion process which helps in grinding the food in the stomach. But the fact is crocodiles can even survive even without eating for months. They are fast swimmers and they mostly catch their prey from underwater and can hold their breath for one hour, but they are really slow inland.

They have extremely good vision, smelling, and hearing sense which are a major advantage for them. As crocodiles are cold-blooded animals, they can’t generate heat on their own. And during the cold months, they become inactive and sleep by digging out a burrow until the climate heats. But this aquatic reptile gets no sweat because of its cooling process of keeping its mouth open. When they eat their prey they get tears because their glands called lachrymal secretes a fluid that cleans their eyes and reduces bacteria.

Crocodiles lay 10 to 60 eggs and these eggs take 55 to 110 days to hatch while taking a maximum of 15 years to mature. When the crocodile lays eggs, the temperature of the nest indicates the gender of the baby crocodile whether it is a female or male. If the temperature of the egg is less than 32 degrees, it is most probably a female and if it is above, it will be a male. Moreover, crocodiles have an average lifespan of 40 years.

Crocodiles are facing illegal killing and roadkill threats. Humans kill them to get their skin to make shoes and bags. In many other parts, crocodiles are killed for extinction and to make the place safer to live and some kill it for meat. Some crocodiles die due to drainage, water irrigation, and filling of wetland. The population of crocodiles should be maintained preventing declination.
