Among the whales with the thickest blubber are the so-called right whales. They are popularly thought to have earned this common moniker during the bloody era of whale hunting in the 19th Century.
拥有最厚海兽脂的鲸鱼称之为所谓的“露脊鲸”——这个公认的绰号源于血腥的十九世纪，那时候鲸鱼遭到人们的捕杀。
“They are slow and fat and when harpooned they float for easier retrieval. Most other whales sink.” says Dr Sam Ridgway, president of the National Marine Mammal Foundation.The whales float because they have a high percentage of lipids, or fat, in their blubber. There are three species of right whale, found in the North Atlantic, North Pacific and Southern Oceans.
国家海洋哺乳动物基金会主席山姆博士说道：“‘露脊鲸’移动速度慢、身体肥硕庞大，被鱼叉杀死后会飘起来更容易被搜寻到。而其他鲸鱼则会沉下去。”露脊鲸之所以会漂在海面上是因为它们的体脂含量较高。露脊鲸一共有三种，分别生活在北大西洋，北太平洋，南部海域。
