This is, surely, great news! We've been trying so hard to wipe out all the 'vermin' that we are forced to 'share' this planet with - and now we've succeeded with these pesky dolphins!

Only a few more million species to go and then we can have the whole place to ourselves. Perhaps we can look forward to the day when we've concreted it all over and we're all jammed in shoulder to shoulder, fighting for air ... it'll be really great ... won't it?
