THE KILLER whales that roam the waters of the Monterey Submarine Canyon, off the coast of California, are brutal animals. When hunting grey whales, they target mother and calf pairs, chasing them until the calves begin to tire. At that point the killer whales separate the grey whales by manoeuvring between them or dragging the calves away by their tail flukes or fins. Once a calf is separated from its mother, the killer whales incapacitate it by bludgeoning it with their heads and tails before drowning it by leaping atop its blowhole to keep it below the surface.
在加利福尼亚沿海的蒙特雷海底峡谷（Monterey Submarine Canyon）水域游荡的虎鲸（俗称杀手鲸）是凶残的动物。它们捕猎灰鲸时，会盯着成对的母鲸和幼鲸，一路追逐直至幼鲸精疲力竭。这时，虎鲸会在两者之间机动穿梭，或者拖拉幼鲸的尾巴或鳍把它拖走。一旦幼鲸与母鲸分开，虎鲸就会用头部和尾巴猛击幼鲸，使其失去行动能力，然后跃到它的背上压住喷水孔，使其不能浮上海面而溺死。
- roam 表示人或动物“漫步、漫游、游荡、随便走”等，主要指在广阔的区域或很远的地方以自得其乐的愉快心情，漫无目的地或杂乱无章地自由漫游（参见：小词详解 | roam）
- calf （象、鲸等的）崽，幼兽
- manoeuvring （使谨慎或熟练地）移动，运动；转动

- fin （鱼的）鳍

- blowhole （鲸头顶的）呼吸孔；（供海豹等呼吸的）冰窟窿
The killer whale (Orcinus orca) is a diverse species, boasting several isolated populations around the world that occupy varying—and, in several cases, still little described—ecological niches. Two recent studies have shed some light on the unique hunting cultures of the killer whales that stalk the deep waters off the north-east Pacific Ocean.
虎鲸是一个多样化的物种，在世界各地有多个孤立的种群，占据着不同的生态位——其中一些至今仍然鲜有记载。最近两项研究探究了在太平洋东北部深海中潜行的虎鲸，揭示了它们独特的狩猎文化。
- niche 生态位（一个生物所占生境的最小单位）
- stalk 偷偷接近，潜近（猎物或人）
