Inland taipan

The inland taipan (*Oxyuranus microlepidotus*) is a highly venomous snake.

It is found in the semiarid regions of central east Australia. Many people call it the western taipan or the small-scaled snake. It is also known by the name "fierce snake." This name refers to its powerful venom rather than its behavior. In fact, the snake is usually shy and reclusive. It prefers to escape from trouble whenever it can.

The venom of the inland taipan is considered the most toxic of all snake venoms. Scientists measure this potency using LD50 tests on mice. In these tests, the inland taipan is the most toxic of all species tested. Its venom is even more potent than that of many sea snakes. This high toxicity is because the snake is a specialist hunter of mammals. Its venom is specially adapted to kill warm-blooded species. One single bite contains enough venom to kill more than 100 men of average size.

When the snake bites, the venom affects the body in specific ways. It can cause coagulopathy, which is a condition affecting how blood clots. This can become well established within 30 minutes of a bite. The venom also causes neurotoxic paralysis. This paralysis usually takes between 2 and 4 hours to become clinically detectable. During an attack, the snake is extremely fast and agile. It can strike with extreme accuracy and often strikes multiple times in one attack. In almost every case, the snake envenomates its target during these strikes.

The history of this snake is full of mystery. Frederick McCoy first described the species in 1879. He called it *Diemenia microlepidota*. Later, in 1882, William John Macleay described a specimen as *Diemenia ferox*. For 90 years, the scientific community knew very little about the snake. No new specimens were found during this long period. It was not until September 1972 that the snake was rediscovered. Herpetologists Jeanette Covacevich and Charles Tanner traveled to the Channel Country in southwest Queensland. They found 13 living specimens near Windorah.

Taxonomy, or the science of naming and classifying organisms, has changed for this snake. In 1896, George Albert Boulenger placed both earlier descriptions into the genus *Pseudechis*. In 1956, J. Roy Kinghorn suggested the genus *Parademansia*. Later, in 1963, Eric Worrell suggested the inland taipan was the same species as the coastal taipan. After the 1972 rediscovery, researchers like Covacevich and Wombey worked to clarify its classification. The snake's name has shifted as scientists learned more about its true identity.

Despite its deadly venom, the inland taipan is not the deadliest snake to humans. This is because it lives in very remote locations. It rarely comes into contact with people. Most people will never encounter one in the wild. However, it is still a very capable striker. It will defend itself if it is provoked or prevented from escaping. This makes it a significant subject for researchers studying venom and biology.

The inland taipan provides important connections to the study of biochemistry. For example, its venom is the most toxic of any reptile when tested on human heart cell cultures. In these tests, the venom killed over 60% of heart cells within the first 10 minutes. This demonstrates how specialized the venom is for its role in the ecosystem. By studying these chemical processes, scientists can better understand how toxins interact with living cells. The study of the inland taipan helps us understand the complex relationship between predators and their prey.
