7. My favorite snake: its shape and how to eat. My favorite animal is a snake. It is a reptile and a carnivore.
They have no limbs and long bodies. The newborn snake is one centimeter long, and the largest snake is about two meters. Their mouths are big enough to swallow animals two or three times taller and sometimes an alligator.
A snake can eat more than 1000 mice a year, but poisonous snakes can also hurt people, so snakes are both good and bad for human beings. Snakes are divided into two categories: non-poisonous snakes and poisonous snakes. Non-poisonous snakes and poisonous snakes are easy to distinguish. Let me tell you two first. The snake head is triangular, and the non-toxic snake head is oval.
The head of the golden ring snake in the poisonous snake is also oval, which is not easy to identify. Whether it is toxic or not, we should cherish it.

8. The composition of snakes A child my age must be afraid of snakes. I don't know why, but I'm interested in this reptile. Today, my grandma and my mom went to the snake house in the zoo.
Maybe it's because snakes like dark and humid environment. The snake house is gloomy, and the walls on both sides are inlaid with transparent glass cabinets. This is the home of snakes. Some of these snakes are hiding in small rockeries and sleeping soundly; Some dishes are lazy and motionless on the branches; Some open their mouths as if yawning; Some people stare at the outside as if they were curious about the tourists. Some snakes have protective colors. Even if I put my eyes on the glass, it's hard to find. Maybe that's why snakes are a little scary.
There are two kinds of snakes: poisonous snakes and non-poisonous snakes. Poisonous snakes, which are harmful to people, have fangs in their mouths and shoot venom when attacking other animals. The most poisonous snake in the world is the Australian fine scale snake, and its drop of venom can kill thousands of small mice; The longest snake in the world is 7 meters long, while the smallest blind snake is only 15 cm long. There is also a flying snake. This is a tree snake. The snake with the biggest appetite is the python. The biggest python can swallow a zebra or a wild boar at a time. I once saw a story about the animal world on TV. A python lay in ambush in a pond for four days to catch its prey, and finally caught an antelope and swallowed it whole. It is said that this snake can stop eating in the next year.
There are many kinds of snakes. Through this visit, I found that I still don't know much about the kinds of snakes. It seems that my knowledge is really endless.
9. Write an article about the shape, special skills and living habits of pythons. The main characteristics of pythons are large size and long length. They are the largest primitive snakes in the world, with traces of bands and hind limbs. There is an obvious distance between the degenerated cutin of the hind limbs near the male snake, while the degenerated female snake is easy to be ignored. The body is black, with cloud markings, chloasma on the back and a yellow stripe on each side. It is a national key protected wild animal. Python is also the largest snake species in the world, with a length of 5~ 1 1 m and a maximum weight of 50~ 160 kg, belonging to non-toxic snakes. There are countless kinds in the world. We should be kind to them and learn how to protect ourselves from them.
Python belongs to arboreal or aquatic snakes, living in tropical rain forests and subtropical humid forests, and is an omnivorous snake.
The feeding habits of pythons
Pythons often feed on muntjac, wild boar, rabbits, squirrels and poultry. Have a large appetite and can swallow animals that are equal to or overweight at one time. For example, Wuzhou Foreign Trade Warehouse in Guangxi bought a python weighing 10 kg at 1960 and swallowed a domestic pig weighing 15 kg. Strong digestive ability, except the animal hair of prey, it can be digested, but it can be eaten for several months when full. [ 1]
Diet style
Pythons catch prey, big or small, and swallow it without chewing. This swallowing style of pythons mainly comes from the special structure of their jaws. Their lower bones are composed of two independent parts, which can move alternately. In order to eat better, the python will bite its prey with its mouth wide open, then close its upper and lower jaws and let each jaw move alternately. If a creature attacks it at this time, it will immediately swallow the food it has vomited and then run away.
Bite the prey by surprise attack, and tightly entangle it with the body, forcing the heart of the prey to stop blood flow, leading to blood flow and death (even if the heart of the prey fails, leading to blood supply) (the conclusion is that the python entangled its prey and died because it stopped the blood flow of the prey, and it has this ability, rather than suffocation as mentioned above).
Python is a carnivore. When attacking prey, the first step is to wrap the upper body. Python's body is very special. It can feel the heartbeat position of its prey. It will do its best around the heartbeat. Tighter and tighter, the prey can't supply blood or oxygen. Respiratory failure, cardiac arrest!
The peak of reproduction rate is from late April to late May, and spawning occurs. The female lays eggs 12~50 at a time. The eggs are white and weigh about 30 grams. Female pythons have the habit of crouching on the egg pile. At this time, they don't eat, their bodies are hot, and their body temperature is several degrees higher than usual, which is conducive to the hatching of eggs.
Agkistrodon halys has 22-44 small poisonous snakes per fetus, which directly gives birth to snakes.
