Meteorologists and biologists have been left
baffled by earthworms raining from the sky over Southern Norway.According to Norwegian news service
The Local, the most recent phenomenon was discovered by biology teacher Karstein Erstad while he was skiing in the mountains.
"I saw thousands of earthworms on the surface of the snow," he said.
"When I found them on the snow they seemed to be dead, but when I put them in my hand I found that they were alive."
He thought they might have crawled through the snow, but rejected this idea, as the snow was over half a metre thick across the mountains.
This is not the only time an area experiencing worms raining from the sky in Norway, with other cases found in Molde and Bergen, both in the south of the country.
One popular theory on random animal rain suggest that the worms may have been lifted up by a violent air pocket and then brought back down miles away from where they started.
Another theory says water spouts, weather systems similar to tornadoes, can travel from seas onto land and pick up vegetation, debris, and small animals, carrying them miles away from where they started before they blow themselves out.
Comment: Of the 200 South African rhino hunts in 2013, only 15 were genuine hunts. The rest were rhinos shot by mostly Vietnamese 'pseudo hunters', who pay for the privilege of trophy hunting but have no intention of ever mounting their trophy on a wall. The economics are simple: the cost of hunting is about US $20,000, but the 3.5 kg horn is worth many times more when ground up into a fine dust, for sale as a 'medicinal' product. Current prices are estimated at up to US $75,000 per kg. It is now known that rhino horns have no medicinal value at all; chemically they are indistinguishable from horses' hooves and human toenails. But Vietnamese traffickers are fuelling demand by marketing new 'benefits' of rhino horn, as an aphrodisiac or a cure for hangovers, or cancer.
