Deadly Sydney animals

Deadly Sydney animals

Deadly Sydney animals may not be front of mind when you think of Sydney. Possibly, you may think of our Opera House, Harbour Bridge, New Years Eve Fireworks or possibly, cute and cuddly animals. Whilst Sydney is all of these thing. It is also home to some of the world’s most deadly animals.

Deadly Sydney Snakes

Of the most deadly Sydney animals, 21 of the 25 most toxic snakes in the world live in Australia. Sydney is home to 4 of these. These are normally in bushlands in and around Sydney. When hiking in the bush around Sydney, ensure that you wear enclosed footwear and walk on the tracks rather than through think grass where possible. If walking through areas where you cannot see your feet, make plenty of noise as this will normally scare off the snakes. Never place your hands into tree hollows where you cannot see what is there. Snakes normally only attack when cornered or someone tries to pick them up or walk on them.

EASTERN BROWN (COMMON BROWN) SNAKE

The eastern brown snake (Pseudonaja textilis), aka the common brown snake, is a highly venomous snake. Considered the world’s second-most venomous land snake after the inland taipan, it is responsible for about 60% of snake-bite deaths in Australia.

EASTERN TIGER SNAKE

Tiger snakes (Notechis scutatus) are a highly venomous snake species. These snakes are highly variable in their colour, named after the banding like those on a tiger. Tiger snakes account for about 17% of snake bite deaths in Australia.

DEATH ADDER

The common death adder (Acanthophis antarcticus) is a species of death adder native to Australia. It is one of the most venomous land snakes in Australia and globally.

RED BELLIED BLACK SNAKE

The red-bellied black snake (Pseudechis porphyriacus) is a species of venomous snake endemic to the city and its surrounds. Averaging around 1.25 m in length, it has glossy black upper parts, bright red or orange flanks, and a pink or dull red belly. It is not an aggressive species and generally retreats from encounters with people, but can attack if provoked. Although its venom is capable of causing significant illness, no deaths have been recorded from its bite, which is less venomous than many other Australian snakes. It is the most commonly spotted snake in Sydney.

Deadly Sydney Spiders

Arguably the 2 most dangerous spiders in the world call Sydney home. Never pick up a spider. Sometimes spiders can live in shoes that are left outside. If leaving your shoes outside always check inside before putting them on. Funnel webs can often be found in swimming pool filters.

SYDNEY FUNNEL WEB SPIDER

The funnel-web spider (Atrax robustus) is often regarded as the world’s most venomous spider. Its bite is capable of causing serious illness or death in humans if left untreated. They are widespread throughout Sydney and are often found in swimming pool filters. They can live underwater at the bottom of swimming pools for up to a week by carrying their own pouch of air. The Sydney funnel-web has a body length ranging from 1 to 5 cm. They are glossy and darkly coloured.

RED BACK SPIDER

The redback spider (Latrodectus hasselti), also known as the Australian black widow is a species of highly venomous spider. The adult female is easily recognised by her spherical black body with a prominent red stripe on the upper side of her abdomen and an hourglass-shaped red/orange streak on the underside. Females usually have a body length of about 1 cm, while the male is much smaller, being only 3–4 mm long.

Sydney’s Deadly Sharks

The world’s 3 most dangerous sharks are found in the waters in and around Sydney. Most shark attacks in Australia are at dusk and dawn and are on surfers whom the shark mistakes for seals. With this in mind, it is best not to go swimming at these times in unprotected swimming areas.

BULL SHARK

The bull shark (Carcharhinus leucas) is commonly found worldwide in warm, shallow waters along coasts and in rivers. It is aggressive in nature and lives in warm, shallow, brackish and freshwater systems including estuaries and rivers. Bull sharks thrive in both salt and fresh water and can travel far up rivers.

GREAT WHITE SHARK

The great white shark (Carcharodon carcharias), also known as the great white, white shark or “white pointer”, is notable for its size, growing to 6.1 m in length. They can live to 70 years or more. Great white sharks can swim at speeds of 25 km/hr for short bursts and to depths of 1,200 m. The great white shark has no known natural predators other than, on very rare occasions, the killer whale. It is arguably the world’s largest-known extant macropredatory fish, and is one of the primary predators of, up to the size of large baleen whales. It is responsible for more recorded human bite incidents than any other shark.

TIGER SHARK

The tiger shark (Galeocerdo cuvier) is a large macropredator, capable of attaining a length over 5 m. Its name derives from the dark stripes down its body, which resemble a tiger’s pattern, but fade as the shark matures. The tiger shark is a solitary, mostly nocturnal hunter. Though tiger sharks are sometimes taken by groups of killer whales. It is considered a near threatened species due to finning and fishing by humans.The tiger shark is second only to the great white in recorded fatal attacks on humans.

Other Deadly Sydney Animals

BLUE RINGED OCTOPUS

Blue-ringed octopuses, comprising the genus are four highly venomous, species, of octopus. They are easily identifiable by their yellowish skin and characteristic blue and black rings that change color dramatically when something threatens the animal. The Blue ringed octopus is one of the world’s most venomous marine animals. They are 12 to 20 cm and are dangerous to humans if provoked. They can inject enough venom to kill a small child.

The advice here is not to be picking up rocks in small rock pools and not to be placing hands in areas of these small rock pools where you can’t see.

HONEY BEE

Of all the deadly animals in the area, the one responsible for more deaths than any of those already listed above. The honey bee (Apis mellifera) is around 15mm long, golden-yellow, oval-shaped with brown bands. Normally 100 honeybee stings can kill a human, however, a single sting can be fatal to someone with allergies which is why they make this list. Whilst not native to Australia, the Honeybee is Australia’s deadliest insect and Sydney’s most deadly wild animal.

Other Deadly Sydney

Sydney is one of the safest cities of its size in the world. It does not have the violent or gun related crime that is seen in many US cities. However, there are a few things that visitors should know to keep safe.

In Sydney, we drive on the left hand side. For international drivers not used to driving on this side of the road, this can cause problems that end in fatalities.

In Australia, most Australians learn to swim at an early age. We also learn about rips in the ocean. These are strong currents that can drag an unwary swimmer out to sea.

Conclusion

Whilst there are more deadly Sydney animals than one would expect in an average city, the chances of seeing any of them in the wild during your visit are next to nil. Even less than that are the chances of dying from one of Sydney’s deadly animals.

87 people die by drowning each year in the whole of Australia

During the period 2000 to 2010 the following shows the number of animal deaths:

  • Horses (77) [incl ponies & donkeys]
  • Cows (33) [incl all bovines, 16 by causing car accidents]
  • Dogs (27) [children under four years old and in elderly people]
  • Kangaroos (18) [mostly related to car accidents]
  • Bees (16) {people with allergies]
  • Sharks (16)
  • Snakes (14)
  • Spiders (0)

As you can see, less than one person per year dies from the teeth, fangs, stingers or tentacles of our deadly Sydney animals on average in the whole of Australia. The chances of dying from one in Sydney are far less.

That being said, if you see a snake in the wild, back away slowly. Don’t try and touch wild animals, especially any on this list. Don’t go swimming at dusk or dawn in known shark habitats. Swim between the flags at patrolled beaches and understand rips.

Not so deadly animals that can cause pain

Apart form the animals listed, there are still blue bottles, mosquitoes, ants and ticks that reside in Sydney that can cause you pain.

Blue bottles live in our oceans and often wash up on our beaches. They have a nasty sting. If stung, best idea is to go to the surf life savers who may have vinegar or similar to put on the sting.

Mosquitoes are common in summer, especially around areas with stagnant waters and are particularly prevalent at dusk and dawn. Whilst those in Sydney are unlikely to cause disease, they can be an annoyance ad their bites can cause pain. There are various insecticides that can be used to warn them away.

Ants can bite and sting and are sometimes found in great numbers. So be careful not to launch your picnic on top of an ants nest.

Ticks are often found in bushy areas. They will find the warmest parts of your body (arm pits, groin, hair). So if walking through the bush, check yourself thoroughly afterwards. Leaving ticks in can cause infection and Lyme disease.
