It’s one of the most elusive snakes in the world: the bushmaster.

它是世界上最难以捉摸的蛇之一：bushmaster。

Meanwhile, in the forests of sub-Saharan Africa, there’s a shorter, chunkier viper that’s even more venomous than the bushmaster.

与此同时，在撒哈拉以南非洲的森林中，有一种更矮、更粗壮的毒蛇， 它的毒性比丛林霸王还要厉害。

This comes in handy for guarding a nest — unlike most other vipers, the bushmaster lays eggs in hollowed-out tree buttresses or burrows made by other animals.

这对于保卫巢穴很方便——不像大多蝰蛇，巨蝮是卵生，产在其他动物挖空的树墩或洞穴中。

This allows the bushmaster to " see" the heat signature of approaching prey or predators, helping it decide whether or not to strike and strike more accurately.

这让巨蝮能“看见”掠食者或猎物接近时的热信号，帮助它决定是否要攻击，而且能更准确。

It must be large enough to defend its nest — in fact, the bushmaster is the largest viper in the world, reaching lengths of over 11 feet, with huge fangs and deadly venom.

必须足够大去保卫它的巢——事实上，巨蝮是世界上最大的蝰蛇，长度可达 11 英尺，有着巨大的獠牙及致命毒液。
