When it comes to toxic animals, snakes are the easiest thing to think of. Most of the world’s most poisonous snakes are in Australia. In the arid plains of central Australia, there is a poisonous snake called the Inland Taipan snake, which is recognized as the most poisonous snake on land. The toxicity of its venom is 300 times stronger than that of rattlesnake and more than 50 times stronger than that of King cobra. Despite the appalling lethal weapons, the Inland Taipan snakes are rarely used. They are shy and flee at sight, but this does not affect its title of “the first venomous snake on land”, because it is “no bite, no bite”. Every time an inland Taipan snake bites a victim, the venom discharged at a time can poison 20 tons of prey, which is equivalent to the weight of 200,000 mice, 100 adults or two African elephants.
The most poisonous snake in the world is the Belcher Sea snake, which lives around the reefs of the Ashmore Islands in Northwest Australia. The toxicity of the Belcher sea snake is about 200 times that of the king cobra. Its toxin is quite mysterious, so far, there has been little research on the toxin of this sea snake. This kind of sea snake is mild in temperament, so there are few reports of Belcher Sea snake biting people.
The sea is a concentration of animal toxins, and also in coastal waters near Australia, there is a zooplankton called the Australian Square Jellyfish (also known as box jellyfish). Its tentacles contain super toxins to human beings. If a person touches their tentacles, he will die in 30 seconds. Along the coast of Queensland, Australia, for more than 20 years, the number of people who died from poisoning by Square jellyfish was five times the number who died at the mouth of sharks. Even when humans encounter tiny cells in the jellyfish, they can cause death.
Among animal toxins, tetrodotoxin may not be unfamiliar to us. It is a highly neurolytic toxin that exists in puffers, salamanders and other animals. Tetrodotoxin is about 500 times more toxic than potassium cyanide, and its chemical properties are stable. It can not be destroyed by boiling water at 100 C for 8 hours. Therefore, the general fried, boiled, fried and so on can not reduce its toxicity, so every year there are cases of death due to the greed for puffer delicacy.
Nowadays, the most toxic animal toxin discovered by human beings is sea anemone toxin, which is a toxin isolated from sea anemone coelenterates. It is the most toxic known non-protein toxin, and its toxicity is tens of times greater than tetrodotoxin. In 1989, this substance was synthesized in the laboratory for the first time, which is also the most toxic compound that we can synthesize at this stage.
