In the next bit， we're going to see a couple squid。 These are squid。 Now males， when they fight， if they're really aggressive， they turn white。 And these two males are fighting， they do it by bouncing their butts together， which is an interesting concept。 Now， here's a male on the left and a female on the right， and the male has managed to split his coloration so the female only always sees the kinder gentler squid in him。 And the male 。。。 （Laughter） We're going to see it again。 Let's take a look at it again。 Watch the coloration： white on the right， brown on the left。 He takes a step back —— so he's keeping off the other males by splitting his body —— and comes up on the other side 。。。 Bingo！ Now I'm told that's not just a squid phenomenon with males， but I don't know。 （Laughter）

　　接下来，再来一起看一对鱿鱼。 这就是鱿鱼。当雄性鱿鱼搏斗时， 如果它们想要显示出自己的侵略性，它们就变为白色了。 这有两条雄鱿鱼在搏斗。 它们用撞屁股的方式来搏斗， 真是挺有意思的方法。这里有一条雄性在左边， 雌性在右边。 看，这条雄性能有办法利用颜色把自己分为两半， 所以雌性只能看到它温顺，优雅的一边， 雄性—— （笑声）再来看一次。 让我们再看一次。注意它的颜色： 白色在右边，棕色在左边。 它后退一步，让其它的雄性无法靠近 来到另外一边，并且马上转换颜色。 瞧！以前有人告诉我 这个雄性特征不仅仅是在鱿鱼身上，不过我也不太确定。 （掌声）
