Measured by weight, the world’s biggest snake is the green anaconda. It can weigh over 200kg, and the biggest can have the circumference of a tractor tyre. For length it is outcompeted by the reticulated python Python reticulatus, from South-East Asia, which is the world’s longest snake, growing up to 10 metres long, and sometimes found lurking in drains in Singapore.
But the anaconda is surely the king of snakes. The largest one ever found was a female shot in southern Brazil in 1960.
