There is a known as the "tiger of the sea" killer whale, sometimes dozens of head formed a group, surrounded by a more than 30 tons of baleen whales, a few hours ate it up.───有一种号称“海中之虎”的虎鲸，有时好几十头结成一群，围住了一头三十多吨重的长须鲸，几个小时就把它吃光了。

One group of whales has, instead of teeth, long strips of bone, hanging from their upper jaw. This is the baleen whale, the largest animal in the world.───一类鲸鱼，用从上额骨垂下来的长条状的骨头代替牙齿，它就是须鲸，是世界上最大的动物。

But it is easier to hear the baleen whale, with its lower-frequency call, than the beaked whales, says Theriault.───但是，Theriault说，和喙鲸相比，须鲸发出的叫声频率更低，更容易听到它发出的声音。

Moreover, the bones in the front part of a baleen whale's lower jaw, or mandible, aren't fused as they are in other mammals.───另外，须鲸下颚前部的骨骼，也就是所说的下颌骨，并不像其他哺乳动物一样是愈合在一起的。
