Chapter 1: An Overview of Australia's Venomous Snakes

Are Australia's snakes truly the most lethal in the world? This question requires a nuanced examination, focusing on the context rather than just the venom.

The eastern green mamba may not be the most lethal, but its beauty is undeniable, surpassing even the taipan in appearance. Let's delve into the topic of dangerous snakes. Stay with me, as there’s a larger message to convey.

It's common for those outside Australia to highlight the various deadly snakes, spiders, sharks, and jellyfish present in our environment. Statistically, it's true—20 of the 25 most venomous snakes are found here. The inland taipan, for instance, has remarkably potent venom, far surpassing other snakes.

Interestingly, there are no documented fatalities caused by the inland taipan, as it primarily inhabits remote desert areas and tends to be quite docile.

What does "deadly" truly mean in this context? Here are a few considerations:

• How aggressive is the snake?
• How high can it strike? (Some species can reach high enough to bite your torso, while others are limited to leg bites, giving you more reaction time.)
• What percentage of bites are "dry"? (For example, brown snakes, frequently seen on farms, inject venom in only about half of their bites, whereas black mambas always deliver venom.)
• Is there effective antivenom available? (Even with antivenom, black mamba bites still result in a 14% fatality rate.)
• Do these snakes inhabit areas populated by humans?

Australia boasts one of the highest urbanization rates globally, meaning most snakes are found far from human dwellings. Consequently, those who get bitten are usually near well-equipped hospitals.

So, how lethal are our snakes? In the last 20 years, they have caused 35 fatalities, with 20% of these incidents involving individuals attempting to handle the snake. In contrast, the saw-scaled viper is responsible for around 5,000 deaths annually in India, with more fatalities occurring across Africa, Sri Lanka, and Pakistan. Despite the lower toxicity of its venom, the rural population and limited healthcare access contribute to this staggering figure.

The common krait claims about 10,000 lives each year in India, while the Indian cobra causes approximately 15,000 deaths annually. Although India has a significantly larger population than Australia, the per capita data indicates that the snakes there pose a much greater risk.

The same applies to other deadly creatures.

Since the development of antivenom in 1982, there have been no recorded deaths from funnel-web spider bites, once considered the deadliest globally. The redback spider has caused only one death in the last 60 years. Shark attacks have resulted in 15 tragic deaths over the past two decades, and crocodile fatalities occur roughly every year or two in Australia. However, the Nile crocodile leads to hundreds of deaths in Africa annually. Factors such as human-crocodile interactions and healthcare access play significant roles in these statistics.

The overarching message is that a snake's deadliness isn't solely an inherent characteristic of the snake or its venom; rather, it's a complex interplay of environmental and behavioral factors. This principle applies not just to snakes but to nearly all traits, whether positive or negative. One cannot isolate a characteristic from the system in which it exists.
