But she's about to meet her nemesis: the slender mongoose, a notorious snake killer.

不過今天她正好遇見頭號大敵，瘦猫鼬——惡名昭彰的殺蛇高手。

They may look like featherweights in the ring, but these are two of the most lethal predators on the planet.

乍看之下他們也許很瘦小，但這兩種生物都是地球上最致命的捕食性動物。

The mongoose has razor-sharp teeth and lightning speed.

瘦猫鼬有利牙，而且速度非凡。

But one bite from a mamba can kill 15 grown men.

但黑曼巴的一咬，可以殺死十五個成年人。

So imagine what it can do to a five-pound mongoose.

所以想像她能對一隻五磅 (約兩公斤重) 的瘦猫鼬做什麼？

The mamba is lethal, but she's not tough.

黑曼巴非常致命，但她不夠強悍。

She relies on her venom to sedate her victims and immobilize their weapons.

她依靠的是毒液，鎮靜受害者並癱瘓他們的武器。

Here's the kicker.

難題來了。

The mongoose has an antidote to her potion.

瘦猫鼬有毒夜的解藥。

The toxins in snake venom attach to chemical receptors in their victims and block communications between nerves and muscle.

蛇的毒液會連接受害者的化學受器，將肌肉與神經間的連結阻斷。

Mongoose receptors have mutated, so that venom simply bounces off the muscle cells.

不過瘦猫鼬的受器變異了，毒液完全不會影響肌肉細胞。

He's literally immune to danger.

他完全對危險免疫。

The mongoose MO is to dance circles around his prey until it's exhausted.

這隻瘦猫鼬的獵物手法就是不斷繞圈，直到他的獵物筋疲力盡。

And then, the kill shot.

最後，迎來擊殺關鍵。

One swift snap to the back of the head and the spine is severed.

快速地一咬頭的後部，脊椎就嚴重受損。

The snake is still alive, but paralyzed.

這條黑曼巴依舊存活，不過癱瘓了。

Her muscles twitch.

她的肌肉能動。

But her bite is gone.

但已經無法再咬了。

For the mongoose, the reward outweighs the risk.

對瘦猫鼬來說，回報遠大於風險。

A seven-foot snake is a hearty meal for a pint-size predator.

一條七英呎的蛇 (約兩百一十公分)，對小小的捕食性動物來說，是豐盛的一餐。
