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.
This is the dolphin featured in Douglas Adams’s Last Chance to See, which is without doubt his best book. Alas I never caught the radio series, though the site Another Chance to See, has pointed me to an MP3 of the Rodrigues Fruitbat Episode. You can also hear him talk about the Komodo Dragon at the BBC.
