Is the Inland Taipan Aggressive? Why the Fierce Snake Is Shy

Where does the name “fierce snake” come from?

The nickname is misleading. When the inland taipan was described for the second time, in 1882, the naturalist William John Macleay named it Diemenia ferox, and ferox is Latin for “fierce.” The scientific name was later dropped, but “fierce snake” stuck as a common name.

Today the name is usually explained as a reference to the extraordinary strength of its venom, which is the most toxic of any snake in laboratory tests on mice. It says nothing about the snake’s temper. Other common names, such as inland taipan, western taipan and small-scaled snake, describe where it lives and its fine scales instead.

How does an inland taipan behave?

In the wild, the inland taipan spends most of its life hidden. It shelters in deep cracks that open in the clay soil of dry floodplains, and in holes and old mammal burrows. It comes to the surface mainly in the early morning, basks briefly, hunts rats near burrows and then retreats underground for the rest of the day. In cooler weather it may also be active in the afternoon.

When it senses a person nearby, its usual reaction is to flee or to stay still and hope not to be noticed. Snakes sense ground vibrations well, and a person moving quietly is less likely to alarm one. Many experienced reptile keepers describe the species as placid to handle compared with other large Australian elapids, although they also stress that it must always be treated with extreme caution.

The S-shaped warning display

If an inland taipan is cornered, provoked, handled or prevented from escaping, it changes its behavior. It raises the front of its body in a tight, low S-shaped curve, with its head facing the source of the threat. This posture is a warning, and it also puts the snake in position to strike.

If the warning is ignored, the snake may strike with great speed and accuracy, sometimes more than once. In defensive bites it usually injects venom. This is why the species is shy but not harmless: it avoids trouble when it can and defends itself very effectively when it cannot. Anyone who sees one should keep well away and leave it alone. Anyone bitten should seek emergency medical help immediately (000 in Australia, 911 in the US, 112 in the EU or 999 in the UK).

Why it rarely meets people

The main reason inland taipans almost never bite anyone is where they live. The species is found in the Channel Country of central-east Australia, on the border of southwestern Queensland and northeastern South Australia. This is one of the most thinly populated parts of the country, made up of huge cattle stations, gibber plains and floodplains with very few roads or towns.

Even within that range, the snake is above ground for only a few hours a day, mostly in the morning. Its main prey, the long-haired rat, also lives in burrows and soil cracks, so the snake has little reason to come near houses. Unlike some other venomous snakes, it is not drawn to farms, sheds or gardens.

As a result, medical records are very thin. A review of documented cases found only 11 well-recorded envenomings, and just two of those involved wild snakes. Most bites happened to herpetologists, snake keepers and venom collectors working with captive snakes. No death has been conclusively linked to an inland taipan since antivenom became available.

How it compares with the coastal taipan

The inland taipan’s closest relative, the coastal taipan (Oxyuranus scutellatus), has a very different reputation. It lives in northern and eastern Australia and southern New Guinea, often in sugarcane fields, grassland and the edges of towns. It is generally described as more nervous and, when it is confronted and cannot escape, it defends itself vigorously with fast, repeated strikes.

The coastal taipan’s venom is less toxic per milligram than the inland taipan’s, but it delivers more of it, and it lives much closer to people. Before a specific antivenom was introduced in the mid-1950s, its bites were often fatal. For these reasons the coastal taipan, not the inland species, is usually considered the more dangerous of the two in practice.

Are any snakes really aggressive?

Most herpetologists avoid calling snakes “aggressive” toward people. Snakes do not hunt humans, and almost all bites happen when someone steps on, picks up, corners or tries to kill a snake. What differs between species is how nervous they are and how quickly they move from warning to biting. Some, such as the black mamba, have reputations for aggression that are mostly exaggerated, as explained in is the black mamba the deadliest snake?

The inland taipan sits at the shy end of that range. It is a powerful hunter of rats with a venom designed to stop prey in tight tunnels, but toward people it is a retiring animal that would much rather hide than fight.
