Top Ten Of Australia’s Most Dangerous Reptiles

The Most Deadliest Of The Reptile Animals in Australia

When we talk about Australia, we usually consider it the mighty continent with admirable landscapes, wonderful beaches, and beautiful biodiversity. It rarely comes in our mind that Australia is also famous for being home to deadly animals. This bad reputation of Australia has come in front of the world after a stingray killed our crocodile hunter, Steve Irwin. But that does not mean, we will stop dreaming about Australia. Everything comes with a package of pros and cons. Deadly animals are considered as one of the cons of the natural biodiversity of Australia. Some of the most dangerous Australian reptiles are discussed here.

1. Eastern Brown Snake

Eastern Brown Snake is known to be one of the most dangerous reptiles in the world. This snake is held responsible for most of the snake bite fatalities in Australia. The Eastern Brown snake can be spotted all across the continent. It has a length of nearly a meter and some adults can grow as long as two meters. It is a very nervy snake, as soon as you come close to the snake, it can bite you very quickly and then you have very few options left. More than 60% of fatal snake bites in Australia are that of the Eastern Brown Snake. This species of snake is very swift as well as aggressive. These snakes are known to be the second most venomous terrestrial snakes. If the snake feels threatened, it might raise its body above the ground and forms an ‘S’ shape, so who is the heir of Slytherin? The bite of this snake is painless initially, so it is difficult to diagnose. Here comes the problem, because if you are bitten by this snake, you need medical treatment urgently. The venom might be the cause of paralysis and uncontrollable bleeding.

2. Estuarine Crocodile or Saltwater Crocodile

Snakes are not the only dangerous reptiles in Australia. It would be good information if you come to know that the crocodiles are equally interested in killing you. If you are in North Australia, fear crocodiles more than snakes. The saltwater crocodiles or commonly known as Estuarine crocodiles can be found in ocean and estuaries. Sometimes you can also locate them in freshwater. If there is any cautionary sign, or any local tells you about crocodiles, take it seriously, otherwise the crocodile might mind it. These crocodiles are very famous in ambushing their prey. If they might be unable to get you, they can attack your dog, which you have chained up outside your tent. Luckily, unlike snake bite, in this case you can easily know that it has gotten you because its sharp teeth might be clamped around your leg. This species of crocodile is the largest living reptile and measure up to 7 meters. It has a weight of more than 2000 kilograms. These crocodiles are the most dangerous type of animals when it comes to humans, they surely are more dangerous than their friends, alligators. You should always avoid contact with this crocodile because the crocodile might forget it, but you will never. They have such high speed, that running in front of them, may do no good to you. With this power and aggressiveness, humans are their most favourite prey. So when in Australia, and there is a warning for crocodile, take it seriously, very seriously.

3. Coastal Taipan

Another type of reptile, if encountered will not leave you good, is the Coastal Taipan. Scientifically known as Oxyuranus scutellatus is a fatal aggressive snake. Its average length is more than 2 meters. Although this snake is not as aggressive as the Eastern Brown Snake, still it is very active in defending itself and if it considers you a danger, then you are in danger. The snake is very fast and possesses an accurate strike. However, Coastal Taipan is nothing in front of the Inland Taipan. The good news here is, there is a very small chance of your encounter with this snake species, and better news is, there haven’t been any known deaths with its bite. The venom of Coastal Taipan works on mammals by attacking the nervous system and blood. If this species bights you, you might bleed internally and get symptoms like headache, nausea, and vomiting.

4. Common Death Adder

As the name suggests, when encountered with this species of snake, you are not coming back alive. This snake is very common in the Sydney bushland. When you come across this snake, know one thing, make one wrong move and you are gone. This snake, being different from others does not bite you, up till the time you make it bite you. It prefers being camouflaged rather than contacting and preying humans. Unlike other snakes which bite when you come across them, the Common Death Adder freezes. If you are walking in the bushy area and step on one of the death adders, then it might bite you. It has such long fangs which can penetrate deeply in you and might cause paralysis. The Common Death Adders’ bite venom results in loss of motor and sensory neurons that may cause numbness, you will start losing breath, become paralyzed and finally you die. Remember it usually exists in the lead litter, and its tail is a lure for its prey.

5. Western Brown Snake

Scientifically named as Pseudonaja mengden is not as poisonous as its cousin Eastern Brown Snake. The Western Brown Snake is commonly known as Gwardar and is a very common snake species in Australia. The snake can be found in dry habitats, eucalyptus forests, woodlands, grasslands, or we can say any place they might like to. Although its venom is not as fatal as Eastern brown, it still bites with three times as much venom as the eastern brown snake. The snake bite might result in nausea, headache and abdominal pains in humans. If your dog or cat might encounter this snake, the poor soul can get paralyzed.

6. Tiger Snake

Coastal areas, wetlands, and creeks of Southern Australia are home of Tiger Snakes. You would be lucky if you come across any of the family members of Tiger Snakes and it leaves you. These large and poisonous snakes have many cousins around in Australia. Every group of Tiger Snakes is slightly different from others. Some of the Tiger Snake species include Common Tiger Snake, Tasmanian Tiger Snake, Western Tiger Snake, King Island Tiger Snake, Chappell Island Tiger Snake, and Peninsula Tiger Snake. If you are unlucky to be bitten by a Tiger Snake, remember you just have few options to survive. And the best option is to seek medical help urgently. Because, the tiger snake-bitten people, if remain untreated, hardly survive. Although they have different colours and patterns and hence are difficult to identify, all of these are stripped. Their venom is neurotoxic. Amazingly the Tiger Snakes is a protected species in Australia and while they can kill you, you are not allowed to kill them.

7. Inland Taipan

Scientifically known as Oxyuranus microlepidotus, the Inland Taipan has so much venom which is enough to kill more than 100 people. And we are even not kidding, it is the most venomous snake in the whole world. However, if you come across to the Inland Taipan, you might get lucky, because they usually do not have the desire to kill you. It is a reclusive and placid organism that might not be interested in biting you. Also, it is very rare and found in just remote semi-arid regions of Queensland and South Australia. An encounter with an Inland Taipan is so rare that you might encounter a shark on land rather than this snake. It is so rare that till 1972 these snakes were known to the scientists as a mysterious species.

10. Small Eyed Snake

Although they are very small in size and measure only 50 centimetres on average, we should never underestimate their capabilities. The venom of Small Eyed Snake possesses a long-acting myotoxin. This thing penetrates inside the muscle and keeps on attacking for days after the bite. These snakes are very common in the mesic hinterland region of eastern Australia.
