Tiger snakes secrete strong neurotoxins, coagulants, hemolysin, and snake-specific muscle toxins. Different types of tiger snakes have different half-lethal doses of snake venom. From the 0.4-half dose of Chapel Island tiger snake species to low The peninsula tiger snake to 0.12. Being bitten by a tiger snake can quickly lead to respiratory paralysis, and even 60% of cases will lead to death.
Tiger snake (scientific name: Notechis scutatus) is a genus of reptiles in the scaly cobra family. Tiger snakes are poisonous snakes, mainly distributed in southern Australia, including the coast of South Australia and Tasmania. This type of snake has a variety of body colors and body patterns, with shades of shades and twists and turns, just like the markings on a tiger, hence the name. Tiger snakes are protected animals in many countries. The maximum fine for those who kill or harm tiger snakes is US$4,000.
The body of a tiger snake is generally 1.45 meters long, with wide body lines and a clear gap between light and darkness. The body color of tiger snakes is roughly olive, dark yellow, orange-brown, and black, and the snake belly is relatively light. Tiger snakes kill their prey with toxins, and they can also bite fiercely on the invaders, possessing lethal abilities. They can tolerate low temperatures, but for tiger snakes, the best time for activity is warmer nights.
A female tiger snake can give birth to 12 to 40 young snakes at a time. The only record is that an Oriental tiger snake gave birth to 64 young snakes in the past, which is a rare example. Generally speaking, tiger snakes are not strongly aggressive, and if they can do it when they are threatened, they will first escape instead of attacking actively. If the threat is imminent, they will slowly flatten their muscles, raise their heads, and prepare to snap at any time; sometimes they will make a hissing noise to intimidate their opponents.
Although tiger snakes are abundant in southern Australia, they are actually widely distributed. Here are a few main varieties:
Generally, common tiger snakes have a larger head and a thicker body. Their strong muscles allow them to flatten their bodies more effectively and be more flexible when moving or enjoying the sun. Usually the body length is close to one meter, and there are a variety of body colors, mainly brown, gray, and olive. Sometimes, species without tiger stripes are found on the body. The scales are prominent, like overlapping shields, especially the scales near the neck are denser.
The Western tiger snake also has a strong body and a huge head, with a maximum length of two meters. The body pattern on the back is steel cyan and black, and the yellow stripes form a tiger pattern. Some species without obvious body patterns can be found occasionally, and the abdomen is yellow.
The Chappell Island tiger snake is the largest species in the tiger snake genus, with an average length of two meters. The back texture is olive to black and the abdomen is also lighter. This species has a complete staggered body pattern at the young snake stage. The Peninsula tiger snake has an average body length of about 1.1 meters, and its body size is relatively small in the tiger snake genus. The scales near the mouth are white, and the back body lines are black. In the Kangaroo Island area, the peninsula tiger snake has a variety of body colors and rich body structure.
Tiger snakes are mainly distributed on coasts, wetlands or streams, etc. They have the habit of deliberately occupying territories. Some areas inhabited by a large number of frogs or other prey are even more concentrated areas where tiger snakes often live. In addition, there are many seagulls living on the islands occupied by tiger snakes. Tiger snakes will also prey on the babies of these seagulls. However, many larger tiger snakes will be blinded by seagulls pecking. The distribution of tiger snakes extends from southern Western Australia to South Australia, Tasmania, Victoria and even New South Wales. In addition to coastal areas, tiger snakes also frequently appear in inland waterways, and the Murray River. In addition, some tiger snakes that live in wetlands have been affected by the development of the local suburbs in recent years. The number of tiger snakes’ main food sources such as frogs has been greatly reduced, which directly affects the ecology of tiger snakes.
Tiger snakes secrete strong neurotoxins, coagulants, hemolysin and snake-specific muscle toxins, and their venom is among the strongest snake venoms in the world. After being bitten by a tiger snake, in addition to the severe pain of the wound, the toxins extending from the vicinity of the wound will cause pain in the feet and neck. The body will feel numb and sweat, and then breathing will become difficult and local limbs will be paralyzed. Even if there is an effective anti-venom, the fatal rate is still as high as 45% if it is not treated immediately.
The treatment for being bitten by a venomous snake in Australia is roughly the same. Generally speaking, in order to effectively inhibit the spread of snake venom in the lymphatic system, the initial treatment will use the “Pressure Immobilization Method”. During treatment, a wide bandage is tied around the bite wound, and the entire limb (hand or foot) is tightly wrapped and fixed with a wooden board. If there are traces left near the wound of the snake bite, the snake venom may be confirmed and targeted treatment can be applied. The presence of antivenom (or serum) greatly reduces the fatal rate of being bitten by tiger snakes. The current number of deaths caused by tiger snake bites has been surpassed by another type of poisonous snake, brown snake.
Snakes are considered by everyone to be one of the most terrifying animals. Just hearing someone say a snake, you might imagine its hissing sound, or even some goose bumps. What makes us think that snakes are so terrible, besides they will attack you, more importantly, most of them will release highly poisonous. Only a little bit can make you fatal. Today I will introduce you to the ten deadliest snakes in the world. In this list, we will judge the ten most venomous snakes in the world by showing the amount of poison needed to kill the experimental mice in the laboratory. This is the so-called LD 50 or 50% lethal dose. The lower the dose, the more deadly the snake.
