It's a sad day. We must announce that the baiji has gone the way of the dodo. After many days of fruitless searching, research teams on the Yangtze river declared that no living baijis could be found. The blind, freshwater dolphin often got confused by ship's propellers and swam right into them, which sort of sounds like the Darwin Awards of the animal kingdom. Still, extinction day is a sad day. RIP, baiji.
