An Earth-shaking match-up between the Blue Whale and the Argentinosaurus for the title of Biggest!

Who do you think will come out on top?

The biggest present-day animal to swim through the world's oceans at speeds of 5 to 20 miles an hour.
是这位当今世界上最大只的、能以每小时5到20英里的速度游过海洋的动物吗？
Weighing a massive 200 tons, the Blue Whale.
蓝鲸选手：体重达200吨。
Or its worthy contender, one of the biggest dinosaurs ever discovered.
还是它的有力竞争者、迄今为止发现的最大恐龙？
Standing 70 feet tall, measuring an enormous 120 feet long, and weighing more than 10 African elephants, the Argentinosaurus.
阿根廷龙选手：身高70英尺，体长120英尺，体重超过10头非洲象。
Here's our first competitor, the Blue Whale.

There's big and then there's ginormous! This magnificent marine mammal's body can grow up to 100 feet long.

And speaking of big body parts, let's not forget its massive mouth with a tongue weighing as much as an elephant!
说到巨大的身体部位，我们不要忘记它巨大的嘴巴，光是它的舌头就和一只大象一样重！
And a big mouth, means a big appetite! Blue whales bulk up by eating up to four tons a day of tiny shrimp-like creatures called Krill.
而大嘴巴意味着大胃口！蓝鲸每天要吃掉多达4吨的一种虾状生物--磷虾。
Not only is this super-sized sea creature large, it's also loud!
这种巨型海洋生物不仅体型庞大，而且声音也很大！
These goliaths make low-frequency sounds and communicate with other blue whales as far as 1,000 miles away!
这些巨物会发出低频的声音，并与远在1000英里外的其他蓝鲸交流！
Using groans, moans, and whistles, they are able to find food and socialize.

Believe it or not, Blue whales are one of the loudest animals on the planet.

Let's travel back in time to meet one of the biggest pre-historic animals to have ever walked the Earth, the Argentinosaurus!
让我们回到过去，看看地球上有史以来最大的史前动物--阿根廷龙！
This big beast lived during the Cretaceous period, almost 100 million years ago, in what is now Argentina, South America.
这种大型动物生活在大约1亿年前的白垩纪时期，主要活动地点位于现在的南美洲阿根廷。
Surprisingly, this huge dinosaur wasn't a carnivore, but a herbivore.
令人惊讶的是，这种巨大的恐龙并不是食肉动物，而是食草动物。
Feasting only on plants, the Argentinosaurus could devour a buffet-style helping of "salad" fast, and would constantly be on the move to feed their big appetites.
阿根廷龙只以植物为食，它们可以快速地吞下一份自助餐式的“沙拉”，并且会不断地移动以满足它们巨大的胃口。
And all those veggies left a trail of some powerful poop.
所有的这些蔬菜，最终都会变为一坨超大的粪便。
Lucky for us, scientists have been able to estimate just how much. These dung-dropping dinos pooped almost four gallons at one time!
幸运的是，科学家们已经能够估算出这些排泄物的准确重量。这些恐龙一次就能排出近四加仑的粪便!
Woah! Look out below!
哇！小心下面！
This big battle has been a test of how much size really matters!
这场比拼是对体型到底有多重要的一次考验！
Both of these mega-sized monsters top the charts in water and on land.
这两种巨型怪物，分别是水中和陆地上的统治者。
Built with big bodies and big apetites, it's going to be a tough call.
体型庞大，胃口又大，这将是一个艰难的裁决。
Tip to tail, the Argentinosaurus is believed to have been longer than the Blue Whale.
按照从头到尾的长度，阿根廷龙被认为比蓝鲸要长。
But when it comes to weight, the massive Blue Whale smacks down its competition, weighing more than twice as much!
但说到体重，巨大的蓝鲸则击败了它的竞争对手，其体重是阿根廷龙的两倍多!
The title of Biggest goes to the Blue Whale! It's known as not only the largest living animal, but also the largest animal ever!
所以，“体型最大动物”这一头衔属于蓝鲸！它不仅被认为是现存体型最大的动物，也是有史以来体型最大的动物！
