LOOK CAREFULLY, BECAUSE you're probably not going to get the chance to see this little guy up close any time soon. This is the Dampier Peninsula monitor (Varanus sparnus) – the smallest known species of monitor lizard in the world, weighing just over 16 grams and stretching to around 23cm from snout to tail in adulthood.

That's pretty impressive when you consider that the monitor group of lizards also includes the native Australian perentie (Varanus giganteus), which grows to more than 2m long, and the notorious Indonesian Komodo Dragon (Varanus komodoensis) – a force to reckon with at more than 3m long and more 80kg, which makes it the largest lizard in the world.

Only just discovered late last year, the Dampier Peninsula monitor is thought to live exclusively in the Dampier Peninsula of the Kimberley region, north of Broome in Western Australia.

These reptiles are so rarely seen – and active when they are, so good luck getting a useable photo if you do – that the name sparnus is taken from the Greek word for 'scarce'.

And it might be rare and very tiny, but this little lizard knows exactly what it's doing. The researchers that discovered it suspect its species hasn't changed all that much in the past six million years.

"We estimate from the genetic information [that the species] diverged roughly about the same time that chimpanzees diverged from human beings," Paul Doughty from the WA Museum Curator of Reptiles and Amphibians, told Katrin Long at the ABC.

The pretty lady in the photo above is 'Pokey' – picked up in the wild in the Kimberley and brought back to the WA Museum to be raised in captivity. She was put on display late last year so the public could get a glimpse of the newly described species, but according to Doughty, she wasn't too pleased about being cleaned up for the occasion.

"She was shedding over Christmas so I had to tidy her up; she was getting a bit stroppy with that," he told the AAP.

An estimated 5.4 million people are bitten by snakes each year, leading to between 81,000 and 138,000 deaths and many more amputations, according to the World Health Organization. Snakes with very potent venom aren't always the most dangerous to people, however. Most just want to be left alone and won't seek out encounters with humans. From the colorful-but-deadly blue Malayan coral to the sometimes indistinguishable cottonmouth, here are 20 of the world's most venomous snakes.  Inland Taipan Ken Griffiths/ Getty Images Considered the world's most venomous snake, Australia's rare and reclusive inland taipan ( Oxyuranus microlepidotus ) mounts rigorous self-defense when provoked, striking with one or more bites. What makes the inland taipan particularly deadly isn't just its high toxicity, but an enzyme that helps accelerate the venom's absorption into the victim's body. Luckily, the inland taipan is rar...
