Interesting things about snakes

Smelling with a tongue, possessing teeth but not chewing, the ability to fly in the air is one of the interesting things about snakes.

About 3,000 species of snakes exist on the planet, of which about 450 are poisonous. 250 venomous snakes are powerful enough to kill people.

The largest snake is the anaconda snake (often called the python) that is up to 12.3m long, and the smallest snake is the blind-blue snake (brahminy blind snake) that is only 0.9cm long.

The snake has 2 lungs, the liver is as long as a stick, the kidneys and intestines are long. A quarter of snakes have small anus, with scales and a tail that is a bone.

Smelling is the most sensitive senses of snakes. They smell with tongues. Thanks to the fork shaped like a fork, snakes can determine the direction of the smell. Although not audible, snakes can sense sound vibrations. The vision of snakes is very poor.

The snake micro-pe and python have heat-sensing organs on their heads, helping them realize the temperature change to 0.002 degrees Celsius, making them capable of hunting without looking, even in the dark. All snakes are good swimmers. Sea snakes do not have gills and rarely float to the surface. They use oxygen dissolved in water to breathe.

Most snakes have teeth, with two rows in the upper jaw and two in the lower jaw. But snakes do not chew because the teeth are inward. These teeth bite and hold the bait very tightly. Only poisonous snakes have fangs .

The lower jaw of the snake is very flexible. The two jaws of most snakes connect directly to the skull, allowing them to increase their mouth size to swallow larger prey than their trunk diameter. A snake can swallow its prey four times its width.

Usually calves once a year. Many snakes reproduce by laying eggs. Some species keep fertilized eggs in the body until they hatch into a baby and lay. Snakes often choose warm places to lay eggs. Baby snakes use their teeth to break the eggshell to get out. Parental snakes even though the snakes live on their own. Own tiger with gods nest and take care of eggs.

The female serpent only needs to have sex once and accumulates sperm that are large enough to be used gradually over the next 10 years.

The solid heart can slide from 1 to 1.5 times out of its normal position so that the prey can enter the stomach, because there is a bag around the heart.

Snakes move by contracting and stretching muscles along the body. They move quickly, about 12 km / h, so they can't catch up.

Some snakes have the ability to launch or fly more than 13m in the air. During the launch / flight process, the body of the snake snake is in an S-shape. Most flying snakes belong to the genus Chrysopelea .

Snakes do not have eyelids . Replacing the lash is a clear flake that protects the skin. Sleeping snakes open their eyes and curl up. If you eat well, snakes can sleep all day, even weeks. Solid winter sleeps for months.

Snake venom is made up of many enzymes and proteins. It may be a neurotoxin or blood toxin. When it enters the animal's body, the snake's toxins spread quickly and destroy the nervous system or the circulatory system. King cobra can kill elephants with a bite.

Most snakes release poison when biting. But some species, such as cobra, can launch venom to a position 1.5 to more than 2m away from them.

Poisonous snakes contain toxins in the glands near the eyes. The poison that the snake releases does not damage the skin, but can become dangerous to the eyes and open wounds.

The number of people killed by snake bites per year is up to 100,000 people.
