"Essentially, evolution has meant that they have taken everyday molecules and mutated them into toxic molecules," says Dr Graham Nicholson, professor of neurotoxicology at the University of Technology Sydney. "Mutation occurs naturally, and over millions years these organisms Adidas Questar Boost Review

SPURS, TENTACLES AND PROBOSCISES. Australia has its share of potentially lethal stinging species. Ranging from bottom feeders on the ocean floor to air borne insects, these animals inject some of the most potent venom on the planet into their victims.

In addition to similar stinging techniques, venomous species also seem to have commonalities in the toxins they use. In particular, marine species seem to evolve and replicate each other.

As with European wasps, the 1.5cm European honey bee, as unassuming as its seems, is highly dangerous to those who have allergies to their venom. Unlike wasps, however, bees leave their stinging barb inserted in their victim, along with a sack Shop Adidas Crazy 8 Basketball Shoes

1. Box jellyfish Chironex fleckeri

Commonly known as the bluebottle because of the indigo balloon that carries them across the ocean, the Portuguese man of war are known for being some of the peskiest stingers in Australia. The individual 'zooids' are a part of a large colony that makes up one gigantic organism. Each individual has an allocated task for survival and collectively the full colony floats around the ocean, carried by the wind. Like ants, the venom is painful but not usually fatal, unless a severe allergic reaction occurs. Their stinging tails are roughly 15cm long and they cause approximately 10,000 stings every summer.

Associate Professor Bryan Fry, associate professor at the University of Queensland and expert in venoms and associated toxins, has found the same biochemical progress in the venoms of marine species. This evolution has Adidas Basketball Shoes Derrick Rose demonstrated particular closeness between colloids (octopi, squid and cuttlefish), suggesting that is a specific venom that is most effective for a specific prey.

Venom is injected through small receptors along the tentacles and so the severity of the sting correlates to the amount of the tentacle that touches the skin. In addition to being very painful, the venom attacks the muscles around the lungs and heart. As a result, paralysis of both these organs is the main cause of death in untreated cases.

3. Honey Bee Apis mellifera

At nearly 2.5cm long, bull ants are a part of the Australian stinging genus Myrmecia and use their large, pincer like jaws to clamp onto their target and then repeatedly inject their venom with their small stinger. While the venom itself is only painful and not fatal, the allergies of some bite victims require immediate medical attention.

This category of animals differs from snakes and spiders because they don't use fangs to inject venom. Instead, they use various appendages to inject their venom into a victim while hunting or in self defence. Depending on the animal, this venom achieves its purpose by shocking, paralysing and sometime killing the target. As with most venomous species, these animals use proteins to create a toxic and potentially lethal solution.

Bees more deadly than spiders in Australia

Located along the east coast of Australia, European wasps were discovered in Australia in 1959 in Tasmania, and by the late 1970s had migrated to the mainland. Naturally dormant in the European winters, these insects have a particularly long lifecycle in Australia because of the relatively warm temperature. They pack a serious sting when angered. Nesting underground and in the walls of houses, they have been known establish colonies of up to 100,000. Their sting, while painful, is not deadly unless the recipient is allergic to their venom. In these cases, hospitalisation and fatalities are possible.

of venom. This detaches from the bee, killing it. Native Australian bees are much smaller and often don't sting unlike the introduced species. Allergies to the venom are responsible for more annual average deaths than sharks, spiders or snakes separately. Less than three per cent of Australians are allergic to bee or wasp venom.

Approximately one per cent of the global population is allergic to ant venom. These stingers are more dangerous than others not because of the toxicity of the venom, but because of the aggression of Bull ants and how frequently they come in contact with people.

"Selection pressure is what has driven organisms to develop defences that assist them in survival. They will pass those genes on to the next generation," says Graham.

Known for lurking off the coast of Darwin and northern Queensland, the box jellyfish is one of the most potent stingers in Australia. It has been responsible for 70 deaths in the country and takes victims by wrapping its 3m tentacles around the unsuspecting prey. This translucent marine stinger is most prevalent during the summer months and all recorded deaths have occurred between October and May.
