A naked man suffered burns to one-fifth of his body when he tried to set fire to a spider at a nudist resort.
The 56-year-old Sydney man tried to kill what he thought was a funnel web spider by pouring petrol down the spider's burrow and igniting it with a match.
But the fuel exploded and the man was left with burns to 18 per cent of his body, on the upper leg and buttocks.
