What kind of animal has six legs, three body parts and is found pretty much everywhere on Earth?
什么样的动物有6条腿，3节身体，在地球上到处都能找到？
You're right, Squeaks, insects.
吱吱，你说得对，昆虫。
One of the coolest things about insects is that there are so many different kinds.
昆虫最厉害的地方在于它们有很多种类。
Think about some of the insects you already know, like butterflies, bees and ants,
想一些你知道的昆虫，如蝴蝶、蜜蜂和蚂蚁，
They look really different from each other.
它们看起来各不相同。
They're all different shapes, colors and sizes.
它们大小不一、形态各异、五彩缤纷。
Squeaks and I like to go outside and learn more about the insects we find by watching how they move around and what they eat.
我和吱吱喜欢外出，通过观察它们的移动方式和食物来了解更多信息。
Sometimes we find some pretty big ones, but they're not even close to the biggest insects in the world, like this one.
我们有时会发现一些相当大的昆虫，但它们连最大昆虫的边儿都没挨上，比如这只。
This is a titan beetle.
这是泰坦甲虫。
The name titan actually means big or gigantic, which makes sense, because they're huge.
名字中的“titan”确实是大或巨大的意思，这在情理之中，因为它们真的体型巨大。
These beetles can get to be over 16 centimeters long, longer than a dollar bill,
这些甲虫的体长可能超过16厘米，比一美元纸币还长，
Just like other beetles you might know like ladybugs and fireflies,
与你知道的其他甲虫如瓢虫和萤火虫相同，
Titan beetles have four wings.
泰坦甲虫有四个翅膀。
A beetles front wings are hard and act as a kind of protective case for the back wings,
甲虫的前翅很硬，充当后翅的保护伞。
but it's the other ways that titan beetles protect themselves that make them look so fierce.
但泰坦甲虫自卫的方式不同，这让它们看起来很凶猛。
They have sharp spines on their body and their jaws are super strong.
它们的身体有锋利的刺，下颚非常强壮。
A titan beetle can bite down hard enough with its jaws to snap a pencil in half.
泰坦甲虫用下颚可以咬断非常坚硬的物体，能把铅笔咬成两段。
There's no reason to be scared of them, though, Squeaks.
不过，吱吱，你不必怕它。
Even though they're super strong,
尽管它们非常强壮，
scientists who study titan beetles have found out that they aren't aggressive.
但科学家发现它们不具有攻击性。
That means they don't attack people or any other animal unless they're scared.
也就是说它们不会攻击人或其他动物，除非它们害怕。
But there's a lot we still don't know about them.
但我们仍对它们的许多事情不了解。
Scientists aren't sure what adult titan beetles eat if there anything at all.
科学家也不确定成年泰坦甲虫吃什么。
Titan beetles live in the warm wet rain forests
泰坦甲虫生活在温暖潮湿的雨林，
and scientists think baby Titan beetles live underground and eat old and rotting wood，
科学家认为泰坦甲虫幼虫生活在地下，吃腐烂的老木头，
so not only is the titan beetle big, it's also a pretty big mystery.
所以泰坦甲虫不仅体型大，还是一个大谜团。
Another huge insect is the giant Weta。
另一个大昆虫是巨沙螽。
The name that scientists used for the giant Weta means monster like grasshopper and it definitely lives up to its name.
科学家用“giant Weta”表示它是像蚱蜢一样的怪物，它绝对名不虚传。
Giant Wetas live in only one place in the world, in the island country of New Zealand,
巨沙螽只生活在新西兰这个岛国，
it has some relatives that might be around where you live though,
不过它的亲戚可能在你周围，
it's related to the little crickets you can hear chirping outside in the evenings.
它与晚上在外面喳喳叫的小蟋蟀有关。
The giant Weta grows to be about 10 centimeters long,
巨沙螽能长到大约10厘米长，
which is very long, but still shorter than the Titan beetle.
这已经很长了，但仍不及泰坦甲虫。
but the giant Weta is a champion if we measure in another way.
但按另一种方式衡量的话，它是冠军。
That's because the giant Weta is one of the heaviest insects in the world.
这是因为巨沙螽是世界上最重的昆虫之一。
Some giant Weta can weight about 70 grams as much as about 25 pennys.
一些巨沙螽重达70克，大约25个便士那么重。
Giant Wetas are heavier than most mice and even some small birds.
它们比大多数老鼠，甚至一些小鸟还重。
They're too heavy to fly and most giant Wetas don't even jump.
它们太重了，飞不起来，大多数巨沙螽甚至跳不起来。
So we met a long insect and a heavy insect, next let's meet a wide insect, the Atlas moth.
既然我们见过了最长的昆虫和最重的昆虫，接下来我们见见最宽的昆虫吧，阿特拉斯蛾。
It's pretty easy to see why this insect is so big.
我们很容易看到它为什么大了。
Yes, Squeaks, its wing.
吱吱，你说对了，因为它的翅膀。
Atlas moth has some of the biggest wings of any insect on Earth.
阿特拉斯蛾拥有地球上最大的翅膀。
They can get to be over 30 centimetres wide that's about the size of a ruler.
它们的翅膀超过30厘米宽，大约是一把尺子的长度。
Like other moths and butterflies, Atlas moths start out as a caterpillar.
阿特拉斯蛾和其他的蛾类和蝴蝶一样，开始是毛虫。
And these caterpillars are very hungry.
这些毛虫非常饿。
They eat a lot of leaves and they grow to be very fat.
它们吃很多叶子，长得非常胖。
Then they spin a silk cocoon around themselves and change into a moth while they're inside it.
然后它们在自己周围吐丝成茧，在里面变成了蛾子。
Once these moths come out of their cocoons though, they don't eat at all.
一旦蛾子从茧中出来，就根本不吃东西了。
They only live for about five to seven days and that whole time they get all their energy from the leaves they ate as caterpillars.
它们只能活5到7天，在这整个期间，它们的全部能量源自毛虫时吃的叶子。
The name that people from China used for this moth means snake's head.
在中文里，"moth"（蛾）是指蛇头。
And if you look at the tops of an Atlas moth wings,
如果你看阿特拉斯蛾翅膀的尖端，
you can see a pattern that looks a lot like a snake's head.
你会看到很像蛇头的图案。
Scientists think that the pattern might scare away birds or other animals that might want to eat them off,
科学家们认为这种图案能够吓走试图吃掉它们的鸟或动物，
since the pattern looks like a snake that could eat them.
因为这个图案看起来像吃它们的蛇。
Between the titan beetle, the giant letter and the Atlas moth, there are some pretty big insects out there.
除了泰坦甲虫、巨沙螽和阿特拉斯蛾之外，还有一些非常大的昆虫。
What's the biggest insect you've seen?
你见过的最大昆虫是什么？
Do you have questions about insects, other animals or anything at all?
你对昆虫、其他动物或任何事有什么疑问吗？
