Zoologists have developed a plan to save the Yangtze River dolphin, probably the world’s most endangered mammal, from extinction.
They hope to take some dolphins from the Yangtze and rear them in a nearby lake, protected from fishermen.
The species is threatened by overfishing which removes its food, industrialisation, boat collisions, and through being caught in fishing nets.
The most recent surveys found only 17 living individuals.
