  • You're traveling deep beneath the ocean's surface,

    譯者:

  • where faint lights flicker and toothy grins flash.

    你正遨遊於海洋的深處,

  • You are now entering... the Twilight Zone.

    那裡搖曳著微弱的光線, 露齒的奸笑不時閃過眼前。

  • Your mission is to survive these depths

    你現在進到了海洋的 「陰陽魔界」──中水層。

  • and journey to the surface after sundown to feed.

    你的任務是在這個深度生存,

  • You may now pick your player.

    並在日落之後游到表面覓食。

  • Just kiddingyou don't have a choice.

    現在,你可以選擇玩家角色。

  • You're a hatchetfish.

    開玩笑的──你沒有選擇。

  • And almost everything else is trying to eat you.

    你是一隻星光魚。

  • The tools at your disposal are a uniquely shaped body,

    而幾乎所有的生物都想吃掉你。

  • shiny scales, and glowing spots on your belly.

    你用來對治的工具是形狀獨特的身體、

  • You're going to need a lot of skill and a little luck.

    閃亮的魚鱗,以及你肚子上 發亮的斑紋。

  • Your first challenge is to begin your upwards trek.

    你會需要很多技巧和一點運氣。

  • Your swim bladder allows you to precisely control your buoyancy.

    你的第一個挑戰是開始往上跋涉。

  • Come nightfall, you slowly fill it up,

    你的浮鰾讓你得以精準地控制沉浮。

  • becoming less dense and rising towards the surface.

    夜晚來臨,你慢慢給浮鰾充氣,

  • You can't swim fast, but your narrow build makes you maneuverable.

    使你的身體比重變小、往水面上升。

  • This is especially important since predators could spring out of the darkness

    你游不快,但是狹窄的體型 使你更加靈活。

  • at any moment.

    這點尤其重要, 因為掠食者隨時會在黑暗中

  • In fact, a fangtooth is gliding beneath you.

    突然出現。

  • It has the ocean's biggest tooth-to-body size ratio.

    事實上,有隻狼牙魚正在你底下掠過。

  • Food is hard to come by in the Twilight Zone,

    這種魚有海洋動物中 佔身體比例最大的牙齒。

  • so predators have fearsome adaptations to make every attack count.

    在中水層裡,食物很難取得,

  • The fangtooth's skin is ultra-black:

    所以掠食者演化出嚇人的特徵, 讓每一次出擊都不白費。

  • it reflects less than 0.5% of the light that hits it,

    狼牙魚皮很黑,

  • making this fish particularly hard to spot.

    顏色深到受光照時, 只反射不到 0.5% 的光,

  • Fortunately, the bioluminescent organs lining your belly are regulated

    讓這種魚特別難被看到。

  • to match the intensity and pattern of the faint light from the ocean's surface.

    幸好,你可以調節肚子上 會發出生物光的器官,

  • This counter-illumination disguises your silhouette.

    以模擬來自海洋表層 微弱光線的強度與規律。

  • So when the fangtooth gazes upwards, you're almost invisible.

    這種消光機制可以隱藏你的輪廓。

  • A bright spot appears in the distance.

    所以當狼牙魚往上注視, 你幾乎是隱形的。

  • You go to check it out, but something's looming in the darkness.

    遠處出現一個亮點。

  • The light is a bioluminescent lure belonging to an anglerfish.

    你上前查看,但有東西 自黑暗逐漸逼近。

  • You dart away before it quickly opens its jaws,

    這道光是鮟鱇魚會發光的誘餌。

  • sucking in a hapless fish that got too close.

    你在他迅速張開大嘴前就迅速遠離,

  • Another narrow escape, but you're nearly there.

    有隻魚游得太近,不幸被大口吞下。

  • Although more than 90% of deep-sea creatures are bioluminescent,

    又一次死裡逃生,但是你就快到了。

  • only one group produces the color red: dragonfishes.

    雖然超過 90% 的深海生物會發光,

  • One of them is near.

    但只有其中一種可以發出 紅色的光,即是巨口魚。

  • Because red light is quickly absorbed by seawater,

    不遠處就有一隻。

  • most deep-sea inhabitants can't see it.

    因為紅光很快就會被海水吸收,

  • The dragonfish emits red light from organs by its eyes,

    許多棲息深海的動物看不見紅光。

  • using an invisible headlight to locate unsuspecting prey

    巨口魚從眼睛周邊的器官發出紅光,

  • that its scoops into its cavernous jaw.

    使用這道隱形的頭燈尋找 毫無防備的獵物,

  • You can't see your enemy,

    並將其一口吞入寬大的虎口裡。

  • but your silvery, mirror-like scales scatter and soften direct light,

    你看不見你的敵人,

  • keeping you hidden.

    但是你銀亮如鏡的魚鱗 分散減弱直射的光線,

  • After three close calls, you reach... the Photic Zone.

    把你藏的很好。

  • You've just participated in the world's largest migration.

    三次僥倖脫險後,你抵達了透光層。

  • It takes place every night as trillions of organisms rise from the ocean's depths

    你剛才就參與了世界上 最盛大的洄游現象。

  • to enjoy the surface's rich resources under the cover of darkness.

    這現象每晚都會發生, 幾兆的生物從海洋深處湧升,

  • The payoff is huge.

    在黑暗的掩護之下 享受表層的豐富資源。

  • Here, your light-sensitive eyes take in a buffet of small crustaceans

    旅程的回報十分豐厚。

  • and gelatinous zooplankton.

    這裡,你那雙對光敏感的眼睛 看到的是充滿小型浮游生物

  • During the day, phytoplankton use sunlight to turn dissolved carbon dioxide

    和膠狀浮游生物的大餐。

  • into energy and build their own cells.

    浮游植物在白天期間利用陽光 將溶解的二氧化碳轉變為能量,

  • They become food for small grazers, forming the base of the food web,

    並用來建造自己體內的細胞。

  • which extends back down to the Twilight Zoneand beyond.

    它們成為小型刮食動物的食物來源, 形成食物網的底層,

  • Organic matter generated up herelike bits of skin, poop, and dead animals

    食物網隨著深度延伸至 中水層,甚至更遠。

  • eventually sinks or is transported in the stomachs of animals

    有機物質在這裡產生, 像是皮屑、排泄物、屍體的碎屑,

  • returning from their nightly migrations.

    這些物質最終會下沉, 或是在動物從每晚的迴游

  • These materials then feed the creatures below that don't migrate.

    回來之後,被吃下肚。

  • This ensures that some of the carbon from the atmosphere

    這些材料接著餵養底下 不會迴游的生物。

  • is locked away in the ocean for hundreds of years to come.

    這些確保大氣層中部份的碳

  • That's why this process is known as the biological carbon pump.

    被鎖在海洋中數百年。

  • Without it, there'd be much more carbon dioxide in the atmosphere,

    這就是為何這過程被稱作生物碳幫浦。

  • where it contributes to climate change.

    如果沒有生物碳幫浦, 大氣層會存在非常多二氧化碳,

  • Your avatar, the hatchetfish, is part of this crucial process.

    並造成氣候變遷。

  • Your first quest is complete,

    你的角色,星光魚,也是 這關鍵過程的一份子。

  • but you must repeat this journey every night for the rest of your life.

    你已完成第一項任務,

  • As the sun rises, the surface becomes dangerous,

    但你必須在「魚生」中的每晚 都進行這趟旅程。

  • and you descend back into the shadows of the Twilight Zone.

    太陽升起,表層變得危險,

You're traveling deep beneath the ocean's surface,
