Vicki Stein: 我是一名科学作家，曾在蒙特雷湾的鲸鱼观察船上工作。不同种类的鲸鱼游泳速度差异很大。须鲸是滤食性动物，体型较大，有些须鲸速度很快，例如鳍鲸，时速可达25英里。而座头鲸和灰鲸体型较不流线型，速度较慢，大约每小时3到4英里。从圣迭戈到东京的距离大约是5500英里。如果条件理想（鲸鱼健康，天气良好），鳍鲸大约需要220小时，也就是9天多一点的时间。而对于速度较慢的座头鲸和灰鲸，则需要大约60天。需要注意的是，鲸鱼通常不会从圣迭戈游到日本，这不是典型的迁徙路线。灰鲸的迁徙路线是夏季在阿拉斯加附近觅食，冬季则游到巴哈加利福尼亚州繁殖和过冬。 Loretta Lobster: 鲸鱼的游泳速度取决于体型。体型流线型的鲸鱼，例如鳍鲸，速度更快，从圣迭戈到东京大约需要九天。而体型较不流线型的鲸鱼，例如座头鲸，速度较慢，大约需要60天。

Whales are some of the biggest animals on the planet, and they often migrate incredible distances. But how fast can they go? Like, let’s say a whale swam from California to Japan – how long would that take? We asked science writer and whale expert Vicky Stein to help us find the answer.
