Hedgehog? Sea urchin? Or Plastic ball?
According to a news headline in The Times, giant hedgehogs are to be employed to protect fish from flying predators – not in some lush exotic rain forest populated by all sorts of strange forms of life, but in County Durham.
Weighted plastic balls, 1 metre in diameter, colour unspecified, are said, in the article below the headline, to resemble giant white sea urchins but are known as hedgehogs (grey/brown). They will be dropped into the River Wear in the hope that they will prevent herons or cormorants or other predators from catching fish.
How will the poor herons survive?
Can we look forward to seeing films of this made by the BBC Natural History Unit?
