It has been nearly 150 years since the publication of 20,000 Leagues Under the Sea,
《海底兩萬里》出版至今已近150年，
and scientists are still searching for the truth about many of the creatures and features of the deep.
科學家仍在搜尋關于很多生物的真相和深海的特點。
"IMMORTAL" JELLYFISH. Could this tiny jelly hold the secret to curing cancer?
“不朽的水母”。這種小小的果凍生物能蘊含著治療癌癥的秘密嗎？
Smaller than a pinkie nail, this creature has the Benjamin Button–like ability to revert to its polyp state,
這種生物比小拇指指甲還小，擁有本杰明紐扣般的能力，可以復原到水螅體狀態，
the earliest stage of its life, when threatened with starvation or injury, earning the nick-name immortal jellyfish for how it appears to outsmart death.
在它生命的最初階段，當受到饑餓或受傷的威脅時，它的智慧戰勝了死亡，因此它獲得了“不朽水母”的綽號。
Although the species, Turritopsis dohrnii, has been known about for a hundred years, researchers didn't discover this capacity until the 1990s.
盡管燈塔水母已經為人所知約一百年，但是研究人員到20世紀90年代才發現它的能力。
They are now wondering whether the jellyfish's ability to regress and regrow could help fight diseases such as cancer in humans.
他們現在想知道水母的復原和再生長的能力是否能幫助對抗比如人類的癌癥等疾病。
GIANT OARFISH. These snakelike creatures are the longest bony fish on Earth—they can grow to up to 56 feet.
皇帶魚。這些蛇形生物是地球上最長的硬骨魚——它們可以長到56英尺。
But they live at depths of around 3,300 feet, so not much is known about them.
但它們生活在大約3300英尺的深處，所以我們對它們知之甚少。
Two dead giant oarfish were found on California's shores in 2013,
2013年人們在加利福尼亞海岸發現了兩條死亡的皇帶魚，
prompting scientists to study samples from their remains to see whether storms, starvation, or illness potentially caused their deaths.
這促使科學家研究它們遺體的樣本，以考證是否暴風雨、饑餓或者疾病會導致它們死亡。
THE PURPLE ORB. In 2016, researchers found a single purple blob about the size of a pool ball in an underwater canyon off California's coast.
紫色球體。2016年，研究人員在加利福尼亞海岸的水下峽谷發現了一個臺球大小的紫色球體。
Stumped as to what it could be, they nick-named it Blobus purpilis. Research is ongoing, but one hypothesis is that it is distantly related to snails.
他們被這可能是什么難住了，給它起了個綽號叫“Blobus purpilis”。研究仍在繼續，有一種假設是它和蝸牛有遠親關系。
CHALLENGER DEEP. This spot in the ocean near Guam is the deepest point on Earth—nearly 7 miles down.
挑戰者深淵。這個關島附近海洋中的地方是地球上最深的地方-有將近7英里深。
(Mount Everest is only 5.5 miles tall.) Located in the Mariana Trench, Challenger Deep has been visited by just three people:
（珠穆朗瑪峰只有5.5英里高。）挑戰者深淵位于馬里亞納海溝，只有三個人參觀過：
two oceanographers in 1960 and filmmaker James Cameron in 2012.
兩位海洋學家于1960年到過那里，還有導演詹姆斯·卡梅隆在2012年到過那里。
It's completely dark and only a few degrees above freezing in the trench, and the pressure is intense: eight tons per square inch.
那里完全是黑暗的，海溝里只比冰點高幾度，而且壓力很大：每平方英寸8噸。
But marine life has managed to thrive. In fact, some researchers believe that life on Earth may have originated there.
但海洋生物卻成功地在此繁衍生息。事實上，一些研究人員認為地球上的生命可能起源于那里。
