A beautiful but deadly 'Tiffany Blue' snake baffled locals when it slithered into a home in Thailand.

The rare turquoise reptile sparked alarm when it was spotted lurking under a tree in homeowner Seubsawat Pakpiboon's garden on May 5.

He called snake expert Ratha Tapianthong, having learned of the snake's potent venom on the local news last year.

Footage shows Ratha combing through the greenery and fearlessly plucking the serpent barehanded. She placed it inside a small mesh sack to be released into the forest.

Ratha said: 'Tiffany Blue snakes are green pit vipers that turn blue. They carry a venom that is dangerous to the nervous system.

'They are similar to cobras, which, when albino, transition from their usual black hue to white.'

Seubsawat said he had first seen the snake after the New Year, lingering among his potted plants. However, it later disappeared before it was seen again this week.

Another 'Tiffany Blue' snake was caught in Ratchaburi province, Thailand, last October. A superstitious Thai pensioner named Gosorn, 62, saw the reptile and thought it was a lucky omen because of its unusual colour.

She claimed she won the lottery because of it, and had it captured by her grandson Adisak, 27. The family now keep the snake as a lucky charm in their garden, allowing it to coil around tree branches and occasionally feeds it insects.

Tiffany Blue snakes are not specific species but a nickname given to certain snakes with an unusual blue color caused by a genetic mutation.

The green pit viper carries a powerful venom that causes bleeding, pain, swelling, nausea and vomiting. In severe cases, victims can lose their limbs or die.
