By going down there and studying things like ctenophores, comb jellies, jellyfish, copepods, weird bioluminescence worms, we can learn from them.

通过深入研究像栉水母，栉水母，水母，桡足类动物，奇怪的生物发光蠕虫，我们可以从它们身上学到东西。

Some sea animals, like jellyfish, comb jellies and salps can migrate between depths partially because their 90% water consistency allows them to withstand immense pressure.

在猎物遁走前抓住它有些海洋动物，比如水母，栉水母，还有樽海鞘可以在不同深度水域中移动部分原因是它们身体有90%的组成是水。

In fact, they might've been the earliest branch, though some scientists think ctenophores -- also known as comb jellies -- might've come first.

事实上， 它们可能是最早的分支，尽管一些科学家认为栉水母——也被称为梳状水母——可能是最早出现的。
