水手中长久以来流传着一种迷信：鼠海豚会将溺水者推向水面从而将其救起，或者将人团团围住形成防御阵形，使其免遭鲨鱼袭击。
There has long been a superstition among mariners that porpoises will save drowning men by pushing them to the surface, or protect them from sharks by surrounding them in defensive formation.
海洋馆的生物学家已经指出，无论鼠海豚多么聪明，将任何救生动机归于它们可能都是一个错误。
Marine Studio biologists have pointed out that, however intelligent they may be, it is probably a mistake to credit dolphins with any motive of life-saving.
在那些它们将无意识的人推到岸边的情形中，它们很可能是出于好奇心或游戏本能而这样做的，就像它们乘骑船头浪一样。
On the occasions when they have pushed to shore an unconscious human being they have much more likely done it out of curiosity or for sport, as in riding the bow waves of a ship.
1928年，一些鼠海豚被拍到像河狸一样努力工作，将一张浸水的床垫推上岸。
In 1928 some porpoises were photographed working like beavers to push ashore a waterlogged mattress.
如果正如已有报道所称，它们确实保护过人类免受鲨鱼侵害，那么其原因很可能是：好奇心吸引了它们，而一顿潜在大餐的气味则吸引来了鲨鱼。
If, as has been reported, they have protected humans from sharks, it may have been because curiosity attracted them and because the scent of a possible meal attracted the sharks.
鼠海豚与鲨鱼天生就是死敌。
Porpoises and sharks are natural enemies.
在这种场合下，完全有可能爆发了一场战斗，鲨鱼或被驱走，或被杀死。
It is possible that upon such an occasion a battle ensued, with the sharks being driven away or killed.
不论是鸟类、鱼类还是其他动物，鼠海豚对任何有生命的东西都深感兴趣。
Whether it be bird, fish or beast, the porpoise is intrigued with anything that is alive.
它们不断地追逐海龟，而海龟则平静地忍受着各种各样的凌辱。
They are constantly after the turtles, who peacefully submit to all sorts of indignities.
有一头年幼的海豚特别喜欢用嘴喙把一只海龟顶到水面，然后像水上飞机一样将它推过整个水槽。
One young calf especially enjoyed raising a turtle to the surface with his snout, and then shoving him across the tank like an aquaplane.
几乎每天都能看到一头年轻的鼠海豚试图将一只重达300磅的海龟翻过来——它用吻部插入龟壳边缘，拼命向上推。
Almost any day a young porpoise may be seen trying to turn a 300-pound sea turtle over by sticking his snout under the edge of his shell and pushing up for dear life.
这并不容易，可能需要两头鼠海豚合力才能完成。
This is not easy, and may require two porpoises working together.
在另一种玩法中，当海龟游过海洋馆时，第一头鼠海豚从上方俯冲而下，用腹部猛撞它的龟壳。
In another game, as the turtle swims across the oceanarium, the first porpoise swoops down from above and butts his shell with his belly.
这把海龟撞得向下沉了好几英尺。
This knocks the turtle down several feet.
它刚一恢复平衡，下一头鼠海豚便随即赶到，再给它沉沉一击。
He no sooner recovers his equilibrium than the next porpoise comes along and hits him another crack.
最终，海龟被一路撞击，一直撞到了水槽底部。
Eventually the turtle has been butted all the way down to the floor of the tank.
它如今只满足于设法站起来，然而只要它一这样做，一头鼠海豚就把它再次撞翻在地。
He is now satisfied merely to try to stand up, but as soon as he does so a porpoise knocks him flat.
海龟终于放弃了，它把四肢缩进龟壳里，游戏就此结束。
The turtle at last gives up by pulling his feet under his shell and the game is over.
