This attaches to a rock or another solid surface where it continues to grow, becoming a polyp.

幼体水母附在岩石或者其他坚硬的表续生长，成为水螅体。

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.

而与蝶不同的是，如果受伤或者生存条件恶劣，灯塔水母们到之前的阶段，在状况改善之前变它们非成熟期时类似水螅虫的样子。

In the case of the immortal jellyfish, after it reaches its mature adult stage it can revert back to the polyp stage before growing into an adult once again.

永生的水母为例，在达到的性成熟的成年阶段后，它转化水螅体阶段，然后再次长成成年水母。
