Many animals have special skills that make them perfect for certain jobs-even better than humans!
Take a train ride in Japan and you may meet Tama，a cute，friendly stationmaster，who just happens to be a cat!This ll-year～old cat works in exchange for cat food at Wakayama Electric Railway's Kishi station．She has her own office，and there's even a Tama train!When Tama was"hired （雇用）"in 2007，the station was losing money，but today，thanks to Tama，it's a popular tourist attraction．
In the 1950s，US Navy （海軍） officials got a great idea．Why not train dolphins to do some special work humans can't do？Today，dolphins are trained to find underwater mines （水雷） so that the Navy officials can make the mines disabled before they explode （爆炸）．Dolphins are well fit for the job for many reasons，but the best of all，they're too small to set off the mines so they're never in danger．
Most squirrels are happy to collect nuts，and run after each other up and down trees．Not Twiggy!She prefers water skiing．Twiggy comes from a team of water-skiing squirrels，whose owner trained them to ski behind a toy boat．Today，Twiggy t．ravels around the United States putting on shows and even appearing on TV．It's all in a day's work for this squirrel!
