Most people are familiar with the snakes in the genus Ringed Snakes are mainly silver-ringed snakes and golden-ringed snakes, mainly because these two snakes are widely distributed in the southern part of the continent and are well known, the other is the Indian ringed snake, the Indian ringed snake is known to everyone may be because they are one of the four major poisonous snakes in India, the four major poisonous snakes in India are the main player of snake injuries caused by India, and the other three major poisonous snakes in India are the Indian cobra, the saw-scale viper and the round spotted viper. The black ring snake is a relatively unfamiliar venomous snake for most people, and they can be said to be a black horse in the genus Ring snake.
The black ring snake is a medium-sized venomous snake, generally about 1 meter in length, and the longest can grow to about 1.3 meters, and they are widely distributed in the terrain, from coastal mangroves to the southern foothills of the Himalayas at an altitude of about 1500 meters. The black-ringed snake is black all over, with no obvious ring stripes, and its belly is yellowish-white. Black ringed snakes are mainly distributed in northeast India, eastern Nepal, Bangladesh, Bhutan and other countries, the venom of the black ringed snake is unique in that in addition to containing a large number of neurotoxins, their venom contains a lot of muscle toxins.
The ringed snake genus is the most lethal snake species for humans, and some of them have the world's top poison, such as the silver-ringed snake, the Sindhi ringed snake and the Indian ringed snake. Ringed snakes are widely distributed in Asia, from southern China, to Southeast Asia and South Asia, and even Iran in West Asia. At present, there are a total of 16 species in the genus, which are the Malay ring snake, the Indian ring snake, the silver ring snake, the Sindh ring snake, the golden ring snake, the Hishan ring snake, the Sri Lankan ring snake, the Suzhen ring snake, the Andaman ring snake, the black ring snake, the red-headed ring snake, the Burmese ring snake, the Worth ring snake, the red river ring snake, the Iranian ring snake and the black ring snake.
At present, a total of 6 cases of black ring snake bites have been recorded in the literature, of which 3 cases died, it can be said that the fatality rate of black ring snake is 50%, if the fatality rate of poisonous snakes is estimated according to the literature records, then the black ring snake can be said to be the highest fatality rate of poisonous snakes in the genus Ring snakes, although their toxicity is a more stretched one in the genus Ring snakes.
In the 3 deaths of the death, the longest of the injured persisted for 47 hours, the shortest only lasted 8 hours, the death time in these deaths is far less than the time of death caused by the silver-ringed snake and the Sindh-ringed snake, generally speaking, the silver-ringed snake bite usually dies within 3-5 hours, the injured person will be bitten by the silver-ringed snake within 40-120 minutes The human body will have respiratory paralysis, respiratory failure and other complications, if not treated in time, the patient will die due to respiratory failure after 3-5 hours, The most poisonous Sindh ringed snake will have less time for the injured.
According to the existing literature in 6 cases of black ring snake bites, of which 3 cases died, on paper it can be understood that the fatality rate of black ring snakes is 50%, but this data is not rigorous enough, after all, the number of people bitten by black ring snakes is still relatively small, these data do not have much reference, in terms of toxicity, the toxicity of black ring snakes is still not as good as most of the ring snake genus of poisonous snakes.
According to relevant records, the lethality rate of the silver-ringed snake in the mainland is about 28%, and the Indian ringed snake has a strong neurotoxicity. In a small bite case study, 9 people were bitten by an Indian ring snake, resulting in 8 deaths, with a mortality rate of nearly 90%; In another study, 35 people were bitten and 27 people died, with a mortality rate of 77%.
