This 2016 video is called Why Australian snakes are so venomous.
Another video, no longer on YouTube, used to say about itself:

A new snake thought to be among the 10 most venomous in the world has been discovered in north-Western Australia. The Kimberley death adder is 50cm long with a pear-shaped head and orange-brown in colour.
From daily The Independent in Britain:
Scientists have discovered a deadly new species of ‘death adder’ in Australia
Wednesday 16 September 2015
Scientists have discovered a new type of snake – the comfortingly-named Kimberley death adder – in an isolated region of Western Australia.
The snake was discovered by a group of scientists from the UK and Australia, and measures around 50cm long.
The death adder is already a known species in Australia’s North Territory, and it was believed that the snakes found further west were simply the same species.
However, the group discovered that the snake found in these regions is a different type, unique to that area.
Death adders truly live up to their name. They’re ‘sit and wait’ predators – hanging around waiting for an unlucky animal or human to pass them by, rather than actively hunting on the move.
Their venom is incredibly deadly to humans, and can cause death from total paralysis and respiratory system in around six hours. It is estimated that around 50 per cent of bites from these snakes were fatal before antivenom was introduced.
Despite this fearful bite, the snake is at significant risk from humans, due to habitat destruction and the introduction of new species.
Speaking to The Guardian, Paul Doughty, curator of herpetology at the Western Australian Museum, said it was “a surprise” to find that this death adder was a completely new type.
He also revealed their unsettling hunting techniques – they dangle their tails like a lure, tricking lizards and birds into coming close.
When they’re within striking range, they lash out and kill their prey.
So the next time you’re in Kimberley, Western Australia, and you see something rustling in the undergrowth – run.
