HAVE you ever heard of a zombie river?

London’s Thames, which back in the late 1950s was declared “biologically dead”, has apparently sprung back to life, according to a study by the city’s Zoological Society.

The State of the Thames has found the river is “home to myriad wildlife as diverse as London itself”, including seahorses, eels, seals, venomous sharks, and the avocet, a bird once thought extinct in Britain.
