Snakes are a very frightening animal. They often come out and come behind their prey without knowing it. Once they attack, they rarely miss their hands. There are various kinds of venom in their bodies, which are used to poison and paralyze opponents.
Although everyone knows that snakes are scary, they often don't know much about snakes, so I will share with you the knowledge about snakes.
Today, I will introduce you a kind of snake, its name is Red Chain Snake.
Red chain snakes are very common in East Asia. They spread from the Far East to the south and southwest of China.
The main difference between this snake and the black-browed snake is that in such a wide area, there are only two subspecies of the red chain snake, which indicates that all subspecies other than the Waltman subspecies are distributed on Ishigaki Island in Okinawa.
Although they have no subspecies, there are certain differences in the morphology of the red chain snakes between the north and the south.
The red-chain snakes in the north are more distinguishable. They are significantly redder and smaller. Only a few red-chain snakes are more than one meter long.
The red chain snakes in the south will be very large, especially in Jiangsu and Zhejiang.
Regarding the diet of red chain snakes, they have a very extensive diet, even more extensive than king snakes.
Such as fish, frogs, etc., as well as some rodents and birds, are one of their food.
The red-chain snakes in the northern mountains are even more peculiar. They even choose to eat coleopteran insects, and they are not limited to young snakes.
The red snakes in the northern mountainous areas of Beijing are very small, and an adult female that can lay ten eggs at a time is not even larger than the thickness of an adult's thumb.
The eyes of snakes are also very interesting. Although almost every animal has eyes, the structure of the eyes of animals is actually quite different.
Human pupils can freely change the focal length, but snakes have only one focal point, so when they see very far or very close objects, these objects are virtual in their line of sight, and the eyesight of snakes is not their main sensory organ .
In addition, snakes also have a third level pupil. Like the eyes of goats, the representative species is the fine green snake. Studies have shown that this level of pupil can slightly change the focal length, so snakes with this pupil have a higher accuracy in biting animals.
This is the characteristic of red chain snakes. If we go out to play, we must pay attention to these animals to avoid being injured by them to our personal safety.
