灯塔水母

But unlike butterflies, if Turritopsis get wounded or if times get tough, they can morph backwards, reverting to their immature polyp form until conditions improve.

与蝴蝶不同灯塔水母受伤或条件艰苦时，会“退化”，保持在不成熟的水螅态直到条件好转。

The animals that can possibly achieve immortality under ideal conditions, such as sea squirts, certain corals, Hydra, and Turritopsis nutricula (the immortal jellyfish), often activate telomerase.

有些动物很可能可以在理想的环境下达到长生不老，比如海鞘、特定种类的珊瑚、九头蛇、灯塔水母（不死的海蜇）。

Because they are able to bypass death, the number of individuals is spiking. They´re now found in oceans around the globe rather than just in their native Caribbean waters.

由于可以绕开死亡，灯塔水母的个体数量非常庞大。它们源自加勒比海，如今已遍布全球海洋。史密森尼热带海洋研究院的Maria Miglietta博士称：´我们看到的是一个全球性的无声入侵。

After reaching sexual maturity, this jellyfish is able to reverse its aging process and become a polyp again.

当灯塔水母生理发育成熟，它们能够逆转自己的老化过程，变回到水螅状态。
