The biggest carnivorous fish The biggest carnivorous fish is the rare great white shark. The average adult great white shark is 4.5 meters long and weighs about 650 kilograms. There is evidence that some great white sharks can be more than 6 meters long. Apart from human deaths caused by wars and accidents, half of the most dangerous animals since the Stone Age are attributed to plasmodium carried by mosquitoes belonging to Anopheles. 1997 According to the estimation of the World Health Organization, malaria still causes 150 deaths every year. The most poisonous animal, the sword frog in South and Central America, can secrete toxic substances. The skin secretion of sword frog is the most toxic. Scientists must wear thick gloves when handling specimens. The most poisonous snake in the world is the Belcher Sea Snake, which lives around the rocks in the ashmore Islands in the northwest of Australia. It is many times more toxic than any land snake. The most poisonous snake on land is a small snake in Western Australia, which is 1.3 meters long. The venom of a snake can kill 250,000 mice. The most poisonous fish, puffer fish in the Red Sea, Indian Ocean and Pacific Ocean, has a deadly toxin, which belongs to one of the most powerful non-protein toxins. This toxin exists in the ovary, blood, lung, small intestine and skin of fish, and 0. 1 g is enough to poison an adult within 20 minutes. The stone fish found in tropical Indian Ocean-Pacific Ocean has the largest poisonous gland, and its fin spines contain toxins, which will kill people if they touch it. /kloc-The venom of the most poisonous jellyfish in 0/00 years, the box jellyfish off the coast of Australia, has killed at least 70 people. It is said that if there is not enough medicine, some victims will die within 4 minutes. An effective defense tool is women's stockings. Jellyfish stinging organs cannot penetrate this substance. Toxins released by the most dangerous sea urchins can cause severe pain, difficulty breathing and paralysis. The most dangerous bees are hybrid bees from Africa, which are not more toxic than other bees, but can be fatal when they bite people in groups. The most poisonous centipede Solomon Islands has a dangerous and strange centipede. It is very toxic and can attack people through forelimbs without jaws. It is said that the victim will put the bitten hand in boiling water to relieve the pain. The most dangerous ant, the fire ant, originated in South America and arrived in the United States with an earth-moving ship in the 1920s. 1995 In May, about 23,000 trout died from eating fire ants in Guadalupe River in central Texas. Fire ants like power supply and often bite off insulators, leading to power failure and fire. The most dangerous bear, the polar bear, is the only bear that actively attacks humans. Most polar bear attacks occur at night. Although most of the most dangerous crocodiles are not recorded, the number of people killed by saltwater crocodiles is still as high as 2000 every year. The crocodile attack that caused the most casualties occurred at the end of World War II, on the night of 1945+09-20 February. At that time, the allies who attacked Rangoon Island in Myanmar trapped 800- 1000 Japanese infantry in a swamp on the shore. By the next morning, only 20 Japanese soldiers had survived, and they were sure that most of the rest had been eaten raw by carp. The most dangerous cats, tigers, attack humans more frequently than other cats, perhaps because of the size of people's prey in tigers, and even for old or injured tigers, they are very easy to catch. The most powerful animal meshing force In the experiment conducted by the Marine Biological Laboratory in Bimini Islands, Bahamas, it was measured that the meshing force between the upper and lower jaws of a 2-meter-long dark-black shark was 60 kg, which was equivalent to biting with teeth with a force of 3 tons per square centimeter. Larger sharks, such as the great white shark, may have greater meshing force, but it has not been measured so far. The longest deadly snake is the mesh snake of the keeper of London Zoo in England, which is usually more than 6.25 meters long. They can entangle their prey with their long bodies and eventually kill it. The fiercest fish, sawtooth fish, attacks all injured animals or creates chaos in the water. It is reported that in 198 1 year, an overloaded ship capsized and sank while berthing in Obidos, Brazil, resulting in 300 people being eaten by sawtooth fish. The most shocking fish, the electric eel, lives in the fresh water of Brazil and Guyana. It has two pairs of longitudinal organs, which can emit 650 volts of electric shock, and its energy can light a light bulb or make adults unconscious. The venom in the glands of the most poisonous lizard, Gila monitor lizard in Mexico and the southwestern United States and its close relative, the Mexican spider lizard, is enough to kill two adults. The most dangerous small mammals are mice, which carry more than 20 diseases, including bacteria that can cause bubonic plague or Black Death. References:
