The world is full of wonders. We used to think that multi-headed animals such as two-headed dragons, three-headed dogs, and hydras all came from fairy tales. But when I saw the blunt-tailed two-headed snake for the first time, I was almost frightened by its two heads. (Inner words: Hasn’t the nuclear wastewater been discharged yet? Why do mutant animals appear?)

Fortunately, its size is relatively small, and it doesn't look aggressive, so the editor got close and observed it. It turns out that its other head is not the real head, but the shape and pattern of the head and tail are very close, which is easy to misread. Speaking of which, is everyone's curiosity attracted by the blunt-tailed two-headed snake? Then don't miss this popular science~

I. Morphological characteristics

First of all, let's talk about its appearance. The blunt-tailed two-headed snake with a total length of only about 35 cm looks very small and flexible. Its body thickness is similar, the tail and head are the same blunt circle, and both ends have similar yellow and black markings, plus its facial features are buried in black scales, if you don't look carefully, it's really It's hard to see where the face is...

Only when it crawls (snakes generally only crawl forward) or spits out letters, we can find its head.

2. Living habits

1. Habitat: So where do such short snakes usually live? Of course it's a cave~ According to research, most of the snakes that live in caves are small and medium-sized snakes. They have the talent to dig holes, but they are generally not poisonous, so they choose to bury them underground to ensure their own safety. The blunt-tailed two-headed snake is one of them.

2. Diet: Because they live in burrows, they mainly feed on neighbors earthworms. In order to find plentiful food, they are also picky about their habitat and often choose to burrow in moist soil.

3. Defending the enemy: In the burrow, their actions are also very secretive, and it is not easy to be discovered by natural enemies. But when going out of the hole, if they encounter natural enemies such as ferrets, badgers, hedgehogs, etc., they have no ability to fight, because it is not poisonous, and the other party is not afraid of biting. At this time, they can only fight for speed. If they can quickly find the hole and drill back to the ground, they will have a chance to survive.

III. Population status

1. Value: Since the blunt-tailed two-headed snake likes to hide in the burrows, it is difficult for us to find it in the wild. whereabouts. And their numbers are very rare, and the research value is very high, so they have long been classified as national protected animals.

2. Distribution: They are mainly distributed in China and Vietnam, and are more common in the central and southern regions of China, such as Jiangsu, Hunan, Sichuan, Guangdong and other provinces, but are less common in the north.

All in all, the blunt-tailed two-headed snake is a very rare species. If you encounter it in the wild, you must not catch it without authorization~
