Where do crocodiles live Where do crocodiles grow?

Freshwater and saltwater are all distributed I know of the largest crocodile is 7 meters long.

Crocodile living habits: 1. Crocodile is a vertebrate amphibian and a reptile. Freshwater crocodiles live in rivers, lakes and marshes, saltwater crocodiles are mainly concentrated in the warm and humid seashore, it is generally 4 meters 5 meters long, the head is flat, there is a very long snout, the whole body is covered with scales, the long tail is flattened, the limbs are short, the forelimbs are 5 toes, the hind limbs are 4 toes, and there are webs between the toes.

2. The image of the crocodile is hideous and ugly, vicious and violent by nature, and its actions are very flexible. It usually sleeps under the shade of the forest or swims underwater during the day, and goes out to forage for food at night. It is an excellent diver and can dive for more than 10 hours.

For example, when encountering predators or hunting food on land, it can jump vertically and catch it, and when it can't pounce, its huge tail can also sweep violently, making it a difficult insect king to deal with.

3. Its regret is that although it has seemingly sharp and sharp teeth, it is a groove tooth, which can grow back quickly after falling out, but unfortunately it cannot bite and chew food. This greatly reduces the function of its strong and long-grown jaws, and since it cannot bite or chew, it can only "clamp" the food like pincers and then swallow it.

4. So when a crocodile pounces on a larger land animal, it cannot bite them to death, but drags them into the water and drowns them; Conversely, when the crocodile pounces on the larger aquatic animals, it throws them onto land, killing the prey from lack of oxygen.

5. When encountering a large piece of food that can not be swallowed, the crocodile often uses its big mouth to "clamp" the food and violently beat it on the stone or tree trunk until it is soft or broken, and then opens its mouth to swallow it.

6. It is precisely because the crocodile's teeth cannot chew food that "God" has allowed it to grow a special stomach. This stomach has a lot of stomach acid and high acidity, which makes the crocodile have the best digestive function. In addition, crocodiles, like chickens, often eat sand and stones, which are used in the stomach to help grind food and promote digestion.

In addition to the seawater, other places are suitable for survival, and generally crocodiles live a little more in Africa and South America, and the crocodiles there are also thick.

Crocodiles like to nest in the shade and hills of the Tamsui River, they like to be about 4 meters away from the river, on the land composed of foliage and thickets, with their tails sweeping out a 7 or 8 meter platform, on which a nest with a diameter of 3 meters is built to place the eggs to be hatched, each nest has about 50 eggs; The eggs are mostly white, each egg is about 80-55 mm in size; When incubating the eggs, the female crocodile waits on the side of the nest, and sprinkles water to wet the nest from time to time, so that the temperature in the ovary is 30 33, and after 75 to 90 days of hatching, the baby crocodile can hatch. Generally, when the young crocodile comes out of the shell, its body length is about 240 mm, it can grow to 480 mm after 1 year, and it can reach 1156 mm in 3 years, weighing about kilograms.

Crocodiles have a fierce and untamed temperament. Adult crocodiles often lurk underwater, leaving only their eyes and nose out of the water to breathe. Crocodiles have sensitive ears and eyes, and when frightened, they will quickly sink to the bottom.

Crocodiles like to surface in the afternoon to sunbathe, and at night crocodiles have bright eyes and young crocodiles have a red glow in their eyes.

Crocodiles mate and breed in May and June of each year, they can mate for several hours in a row, while fertilization takes only 1 2 minutes; July and August are the spawning period for crocodiles. Male crocodiles like to monopolize a piece of their own territory and drive away intruders. In the world of crocodiles, it is usually a male who is a female.

Crocodiles have strong chewing power and can break hard armor, so in ordinary life, crocodiles eat small animals such as fish, frogs, shrimps, and crabs, as well as small alligators, turtles, turtles, and other animals with hard shells.
