But I want to jump up to shallow water now and look at some creatures that are positively amazing.
不過我現在還是想說說淺水里的世界，來看看那些神奇的生物。
Cephalopods -- head-foots. As a kid I knew them as calamari, mostly.
頭足類動物，有頭有角。小時候我把他們當作是槍烏賊。
This is an octopus. This is the work of Dr. Roger Hanlon at the Marine Biological Lab,
這是一條章魚。這是來自Roger Hanlon博士海洋生物實驗室的成果。
and it's just fascinating how cephalopods can, with their incredible eyes, sense their surroundings, look at light, look at patterns.
這些頭足類動物真令人著迷，它用它們的眼睛，它們那難以置信的眼睛來觀察周圍的環境，看光，看圖案。
Here's an octopus moving across the reef, finds a spot to settle down, curls up and then disappears into the background. Tough thing to do.
這有只章魚正在穿過礁石。找到一個位置，停下來，卷起，然后馬上消失在背景之中。這很難做到。
In the next bit, we're going to see a couple squid.
接下來，再來一起看一對魷魚。
Now males, when they fight, if they're really aggressive, they turn white.
當雄性魷魚搏斗時，如果它們想要顯示出自己的侵略性，它們就變為白色了。
And these two males are fighting. They do it by bouncing their butts together, which is an interesting concept.
這有兩條雄魷魚在搏斗。它們用撞屁股的方式來搏斗，真是挺有意思的方法。
Now, here's a male on the left and a female on the right,
這里有一條雄性在左邊，雌性在右邊。
and the male has managed to split his coloration so the female only always sees the kinder, gentler squid in him.
看，這條雄性能有辦法利用顏色把自己分為兩半，所以雌性只能看到它溫順，優雅的一邊。
Let's take a look at it again. Watch the coloration: white on the right, brown on the left.
再來看一次。讓我們再看一次。注意它的顏色：白色在右邊，棕色在左邊。
He takes a step back, he's keeping off the other males by splitting his body, and comes up on the other side -- Bingo!
它后退一步，讓其它的雄性無法靠近，來到另外一邊，并且馬上轉換顏色。瞧！
Now, I'm told that's not not just a squid phenomenon with males, but I don't know.
以前有人告訴我這個雄性特征不僅僅是在魷魚身上，不過我也不太確定。
