Baleen traps prey when the whale expels water.(布賴德鯨通過排出水流就可以捕食獵物。)

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.(有一類鯨魚，用從上額骨垂下來的長條狀的骨頭代替牙齒，它就是須鯨，是世界上最大的動物。)

But it is easier to hear the baleen whale, with its lower-frequency call, than the beaked whales, says Theriault.(但是，Theriault說，和喙鯨相比，須鯨發出的叫聲頻率更低，更容易聽到它發出的聲音。)

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.(有一種號稱“海中之虎”的虎鯨，有時好幾十頭結成一群，圍住了一頭三十多噸重的長須鯨，幾個小時就把它吃光了。)

Surfacing in warm winter waters off the Baja California coast, a gray whale flashes its baleen plates by a boat.(下加利福尼亞海岸(BajaCaliforniacoast)附近，在冬日溫暖的海水里，一條灰鯨浮在水面上，露出了鯨須板，旁邊是一條船。)
