Inland Taipan - World's Most Venomous Snake is Not the Most Dangerous

People have been arguing over the most venomous snakes for as long as I can remember (and I've been keeping and researching snakes for more than 20 years).

The reason there is so much dispute over the most venomous snakes in the world is because people judge them by different criteria, and this inevitably leads to arguments.

For example, some people build their lists of the most venomous snakes by using the LD50 test. LD50 stands for lethal dose 50 percent. In the case of snake venom LD50 is a scale used to measure the potency of a snake's venom. It refers to the amount of venom that, when given all at once, kills 50 percent of the animals tested (mice, in this case).

Other people create lists of the most venomous snakes in the world by considering the venom yield, meaning the amount of venom the snake can produce with a given bite.

Thus, you can probably find dozens of lists that claim to contain the "Top 10 Most Venomous Snakes" in the world, and many of these lists will conflict with each other.

Most Venomous Does Not Mean Most Dangerous

While I'm at it, I'd like to clear up another important point regarding venomous snakes. Many people create lists of what they claim are the "most dangerous" snakes in the world, and they will simply list ten of the most venomous snake as ranked by the LD50 tests mentioned above.

But there is a big difference between a highly venomous snake and a highly dangerous snake. Many snakes that are high on the venom charts are shy and reclusive, and therefore account for very few human fatalities. How could you put such snakes on a list of the world's most dangerous snakes?

On the flip side of that coin, there are certain venomous snakes that, while they do not rank in the top-ten most venomous, still account for a large number of human fatalities each year. This might be because that particular snake is found in highly populated areas far from medical care, that the snake is comparatively more aggressive toward humans, or a combination of these factors.

A good example of this would be the saw-scaled viper (Echis carinatus), which accounts for a relatively high number of deaths in Sri Lanka. While it is certainly highly venomous, the saw-scaled viper does not appear on any top-ten lists of "most venomous snakes." However, it accounts for more deaths than any other snake within its range, largely because of its habit of hiding itself in areas trafficked by humans.

My point is, you cannot make a list of the most venomous snakes in the world and refer to them as the "most dangerous" snakes ... nor the opposite. They are two separate things, and they need to be treated as such.

To echo that sentiment, here's an excerpt from a Princeton University Press interview with Mark O'Shea, snake expert, TV personality and author of the book Venomous Snakes of the World:

"The most dangerous snake is not the most venomous. The most venomous snakes are taipans, Australian brown snakes and sea snakes but they have small venom yields and few snakebites to humans and few human fatalities in the scheme of things ... with that in mind I have encountered many dangerous snakes from rattlers to cobras, sea snakes to desert vipers but I regard the most dangerous snake I have encountered to be the Sri Lankan Russell's viper..."

Most Venomous Snake - Meet the Inland Taipan

Despite all of the semantic arguments and scientific disputes, there is one fact that most people seem to agree on. The most venomous snake, measured by the LD50 test or any type of criteria, is the inland taipan snake of Australia.

The inland taipan (Oxyuranus microlepidotus) possesses the most toxic venom of any snake in the world. But here again, that does not necessarily mean that the inland taipan -- also known as the fiece snake -- is the "most dangerous" or deadliest snake in the world. As we discussed, most venomous does not always translate to most dangerous.

In fact, the inland taipan proves this point for me. Worldwide, more than 40,000 people die each year from venomous snakebite. But Australia only has 2 - 3 snakebite deaths each year. So how can a continent with the world's most venomous snake, the inland taipan, have such a relatively low number of snakebite deaths each year? The answer, of course, is that the inland taipan, while highly venomous, is not one of the deadliest snakes in the world.

Sure, it has lethal venom with the potential to kill humans, but there is a world of difference between potentiality and reality. The inland taipan is the world's most venomous snake by most standards, but is by far NOT the world's deadliest snake.

Are Sharks Stalkers or is It Another One of These Shark Tales?

Shark tales have been partly responsible for Selachophobia which is an obsessive and uncontrollable fear of sharks through the years. Lets just say that movies such as Jaws and Deep Blue Sea also contributed to this phobia and the amount of people that are now affected by it. One of the main problems that the Hollywood versions contributed to is the image of sharks as stalkers and cold blooded killers.

As the fact that sharks are considered being cold blood killers, well, lets analyze this statement to figure out if it is an active member of the shark tales or if it is mainly based on facts. First of all, most sharks are cold blooded, to the exceptions of certain shark species such as the Salmon shark which in some cases make this statement a fact. So, I guess Jaws is cold blooded as it was a great white shark.

Now, lets look at the killer part of the term cold blooded killer. When you consider the fact that sharks must kill living beings, big or small, from plankton to seals, their main purpose being to feed themselves for survival, then I would call them killers just the same as humans who will kill animals to feed themselves.

If on the other hand, you mean to use the term cold blooded killer when talking about sharks, using this term as killing for the purposes of power and taking a life just because they enjoy killing well, you are wrong. In fact, hunters and prize fishermen correspond to this category compared to sharks.

In reality, the facts about sharks that have been discovered by experts show that the brain of the shark is not able of thinking things through, revenge or just to be proud of killing a prey of a certain size like humans do. Humans are the only ones that even show off the head of their prey on the wall.

In fact, sharks do not care for the bony humans. While unprovoked attacks do happen, while rare, they are mainly caused either to protect themselves or simply by confusing humans with a favorite prey such as a seal. So, now we can confirm the fact that sharks are not cold blooded killers, they mainly feed to survive. As a result, we can consider this statement as another one of these shark tales.

Now, are sharks stalkers or is it another one of these shark tales? Well, if you think of hunting for food as stalking, well I guess that you would say that sharks are stalkers as they are stalking their prey. If on the other hand you mean that sharks are stalking humans like the great white shark did in the movie Jaws and its sequels then I would say no. Why? It is simply because sharks brain is not designed for the thinking process or even seeking revenge, it is just too small. Hollywoods magic is responsible for this attribute in their sea monster. In some of Jaws sequels, the storyline even implied that the shark or sharks were seeking revenge. Well, when you consider only the facts and the shark anatomy you know that these attributes are coming from human imagination, not reality.

My name is Sylvie Leochko. The movies Jaws and Deep Blue Sea are amongst the Hollywood creations that made people believe that sharks can be stalkers. Is this another one of these shark tales?

How To Perform A DNA Sample Collection for DNA Testing

DNA testing is most accurate method for confirming biological relationships between individuals. The most common form of testing nowadays is DNA Paternity testing, which is done to confirm the relationship between an alleged Father (and sometimes Mother) and a child.

If you are planning to do a DNA Paternity test, or any other DNA Relationship test, the following article provides you information on how to go about taking a sample of your DNA for DNA testing purposes.

The object of the exercise is to obtain a sample of cheek cells from which the scientists at the lab can extract DNA to match and identify genetic relationships. To do this, you're going to need to take a swab sample from all of the parties involved, that is the mother, father and the child in a traditional paternity test situation. Don't worry - it's not at all painful and the whole process is very simple and straightforward.

To start with, instruct everyone partaking in the DNA test to avoid eating and drinking for at least half an hour prior to giving their sample to avoid any contamination of the sample that may negatively effect the testing. Additionally, it's also advisable to avoid smoking for a period of one hour prior to submitting the sample for DNA testing.

The samples once collected should be clearly marked, labelling both the name and relationship of the party involved on the envelope provided, as well as in the submission sheet you should be provided with the DNA testing kit. The samples of each person should also be kept separate to avoid any risk of cross contamination which would also negatively the results of the DNA test. Normally the envelopes provided are colour coded to provide some form of differentiation. Clear administration of the samples is of paramount importance in protecting the accuracy of the test; therefore it is critical that you follow all instructions contained within your DNA kit sample pack.

When it comes to actually taking the samples, you will require two cotton swabs per person to ensure that in the event one of the swabs does not work, a second sample is available. With the swab end kept free from contact with anything that may contaminate the DNA, rub firmly against the inside of the cheek and tongue to gather saliva and cells which will contain the vital DNA material. In isolation from potential contaminants, and having refrained from touching the cotton end of the swab, the swab should be allowed a minimum period of around 60 minutes to dry off before it is sealed ready to go to the lab. Repeat this process for all the swabs required for each person taking the paternity test.

Once you've collected all the relevant samples and filled in the necessary documentation, it is time to send the pack off to the laboratory performing the DNA testing. It is normally advisable to send the DNA samples through a postal method that can be tracked such as registered mail or courier to ensure it arrives at the DNA testing laboratory.

Depending on how long your particular choice of testing laboratory tends to take, you could be waiting anywhere from a number of days to a number of weeks for the results of the DNA test to arrive.
