Siphonophores repeatedly clone themselves
管水母反复地自我克隆

Question

200m down, you enter the twilight zone...
200米深处是一片黄昏世界
..an alien world, inhabited by creatures beyond imagination.
仿佛置身外星超乎想象的生物生存于此
A siphonophore - with a cloak of lethal stinging tentacles.
管水母身披一层致命的刺触须
Siphonophores repeatedly clone themselves
管水母反复地自我克隆
and so grow to immense lengths.
不断生长体长极长
This one measures 45m and is the longest animal ever recorded.
这一只达到了45米是有记录以来所有动物中最长的
With such deadly predators around,
附近存在着如此致命的捕食者
