The most powerful animal on earth is the crocodile. The crocodile is the largest of the 23 crocodile species and the largest reptile on earth. The Gulf crocodile is also known as the sea crocodile, saltwater crocodile, hooray, man-eating crocodile, estuarine crocodile, Malay crocodile, naked-necked crocodile, etc. It is a crocodile of the family Crocodileidae and is located at the top of the wetland food chain.
Adult crocodiles are 2-7 meters long and weigh 600-1,000 kilograms. Records show that the world's largest crocodile is 7 meters long. The crocodile has 16-19 teeth on each side of its upper jaw and 14-15 teeth on each side of its lower jaw. Because the crocodile is the only crocodile without large scales on its neck, it is also known as the "naked-necked crocodile".
Crocodile, like other crocodiles, also belongs to the dinosaur family. From its appearance on the earth more than 200 million years ago until now, the appearance of the crocodile has not changed significantly. They mainly feed on mud crabs, turtles, monitor lizards and water birds. Some larger adults will even prey on buffalo, livestock, wild boars and monkeys. They will also prey on sharks in the sea. In Australia, the crocodile has been recorded as eating people and even attacking ships, so it is also called the "man-eating crocodile".
The ferocious appearance of the crocodile when hunting makes it a "cold-blooded killer" in people's eyes. The most deadly weapon of the "Killer" is its long, narrow and bloody mouth. This large mouth, which occupies one-sixth of the body length of the crocodile, has a huge bite force, about 200 kilograms per square centimeter, which is more than 10 times stronger than a human bite. However, the crocodile's teeth cannot bite or chew food. It often uses its large mouth to catch prey, drags them to rocks or tree trunks on the water bank, and beats them violently until they are broken or soft, and then eats them bit by bit. . Because the crocodile's teeth cannot chew food, it has a special stomach with the strongest gastric acid among vertebrates. This makes its digestive function very good and can digest any food, including bones. Bay crocodiles sometimes eat some sand and gravel to help themselves digest.
The greatest economic value of the crocodile is the use of its hide to make leather, which is one of the most precious leathers in the world. Crocodile meat is edible, and Burmese people are fond of crocodile meat. Thai people are not fond of crocodile meat but cherish crocodile gallbladder as a treatment for women's infertility. The distribution area of crocodiles is wide and the output is large. In addition to eating meat, Nanyang people also tan crocodile skins to make leather shoes, belts, boxes, handbags, etc. The grains and colors are beautiful, and they are precious decorative leather products. Very high craftsmanship value. As a large reptile, the crocodile also has great ornamental value and is one of the important resources for the development of tourism.
