There was a time when no animals lived on land.

more than half a billion years ago,

This is where all animal body types -- or phyla, as scientists call them -- first evolved.

-
You know, there are more than 30 animal phyla,

but only a handful of major ones had what it took to do something completely daring:
只有少數幾個主要類別 敢踏出最大膽的一步：
-
step out of the ocean, and on to dry land.

So, which of these land-dwelling phyla first invaded the land?
第一批攻上陸地的 陸棲動物是哪一門？
-
Was it me and my mollusc friends, with our amazing mantles and single foot?
是有驚人的外套膜和單腳的我 以及我的軟體動物朋友嗎？
-
Perhaps the chordate crowd, with their notochords, segmented muscles and big bony skeletons.
或有脊索、分段肌肉、大骨架的 脊索動物？
-
Or maybe those lowly annelid worms, with their powerful ringed bodies.
難道是有強大環狀身體的 低等環節動物？

Or did the Arthropods first make landfall, with their little flexible suits of armor -- their exoskeleton?
還是有小小彈性盔甲外骨骼 的節肢動物，最先登陸？

Ah, yes. The arthropods.
噢，答對了，節肢動物
-
From crustaceans to millipedes, spiders to insects,

the arthropods outnumber all animals on land.

So what's their secret?
牠們的秘密是什麼呢？

Their exoskeleton is key, but here's the real kicker: jointed appendages.

-
They're like little living Swiss army knives:
好像小小活生生的瑞士刀

antennae, multiple mouth parts, an obscene number of legs, if you ask me.

that really rule the land.

Three body parts, six legs, and an annoying tendency to take over.

Sure, they have to molt to grow, but that doesn't seem to pose a problem.

The insects even invented the first wings, and conquered the skies.
昆蟲甚至發明了翅膀，征服天空
-
Ah, well. So what if arthropods were the first to reach land
節肢動物首先登陸、
-
and invent flight, a hundred million years before the rest of us?

-
So what if they pollinate crops around the world,

-
and make up 75% of all land animal species?

-
And that for every single human, there's 200 million of them?
相對每個人就有 200 萬隻節肢動物 這些很了不起嗎？

Sure, those leggy arthropods may still be in the lead when it comes to conquering land,
談到稱霸陸地 多腳的節肢動物可能還是領先
-
but we still rule in the sea.

-
There are more species of molluscs in the ocean than any other animal phylum.
海洋中的軟體動物種類 比其他任何動物門都多

We're just getting started up here on land.

Besides, the seas are rising. Just give us some time.

Who knows who'll end up ruling this ocean planet?
