Three snakes twisted in rare ‘mating knot’ writhe together on fence

Three snakes were seen twisted together in a rare mating knot while wriggling on a fence in Thailand.

Bizarre footage shows the trio of intertwined green tree snakes sliding on the edge of a metal fence in Bangkok on July 25.

Nature enthusiast Nam Fang said: ‘I was walking across our neighbourhood when I saw these snakes. It was weird to look at and then I realised they were snakes.’

The snake mating knot, also sometimes called a mating ball, happens when male snakes converge on a desirable female which has been giving off pheromones during mating season.
