New venomous snake species found


 A new species of the highly venomous snake, the death adder, has been brought to attention of Australian scientists. The newly identified species looks very similar to other death adders, with the same brownish tan color and length of 21 inches long. In Australia, this snake is found in the Northern territory where many other adder species are located. This gave them the opportunity to hide in plain site with their similar patterns and size. The death adders are a unique species in how they hunt their prey. They lure small rodents, lizards or other small animals, by shaking their worm like tail. This makes the small animal think their is food but indefinitely their fate is sealed when the snake sinks in their teeth.
"Maddock made his discovery not by trekking through the Australian outback but by studying the DNA of various death adders, a group of snakes native to Australia, New Guinea, and Indonesia that are among the world's most venomous."
Maddock and his team of scientists were gathering DNA from 8 different species of the death adder and found a strange finding. There were DNA samples that just didn't match the rest. He then analyzed 112 specimens in total, including 32 of the new death adder species. This finding came from a simple coincidence and shows the importance of DNA analysis to identify species.

I found this article very interesting and informing. It's exciting that this snake was hiding in plain sight identifying itself as the death adder even though its a subspecies. The technology we have today has made this possible and I'm sure there will be great discoveries within species identification.
