印度洋海底山脉：一次考察揭示 149 个科学界从未描述的物种
An expedition to uncharted seamounts near Australia's Christmas and Cocos islands returned with 149 species new to taxonomy, underscoring how little of the deep ocean has ever been surveyed
中文导读
深海覆盖了地球超过三分之二的表面，却"测绘"得如此之少，以至于科学家常把洋底比作外星世界。一支由澳大利亚顶尖研究机构牵头的考察队，把目标锁定在圣诞岛与科科斯（基林）群岛附近、远离任何大陆架的一连串海底山，最终带回 149 个分类学家从未正式描述过的物种——从梦参属的海参、青眼鱼科的鱼，到附着于其他深海动物身上的寄生生物。这些海底山在数百万年的隔绝中分化出地球上独一无二的动物群，却也因底拖网捕捞与海底采矿而岌岌可危。本文揭示了一个深刻的两难：为物种正式命名需要漫长而艰苦的研究，而人类开采深海的"机器"正加速运转——我们能否在"利用"之前，先"认识"这些地方？

【1】The deep ocean, which covers more than two-thirds of our planet, remains so poorly charted that scientists routinely compare its floor to the surface of an alien world. A single expedition, mounted near two remote Australian territories, has just shown how little of that world has been surveyed — by returning with 149 species that no taxonomist had ever formally described.
【2】Led by marine biologists from Australia's principal research institutions, the voyage targeted a chain of seamounts, the ancient underwater volcanoes that rise thousands of metres from the abyssal plain of the eastern Indian Ocean near Christmas Island and the Cocos (Keeling) Islands, a territory lying far beyond any continental shelf.
【3】The haul, which astonished even seasoned researchers, ranged across the tree of life: a sea cucumber assigned to the genus Oneirophanta, a greeneye fish of the family Chlorophthalmus, and a parasitic creature that attaches itself to other deep-sea animals, together with dozens of corals, sponges and worms.
【4】To survey habitats that sunlight never reaches, the team relied on remotely operated vehicles and baited cameras, which descended more than 4,000 metres to film and collect specimens from slopes that had never been disturbed by human activity. Each specimen, once retrieved, entered a slow pipeline of morphological and genetic analysis — the only route by which a nameless organism becomes a named species.
【5】Seamounts, the researchers argue, function as islands of life in an otherwise barren seascape. Isolated for millions of years, their summits and flanks have allowed countless lineages to diverge into forms found nowhere else, making each mount a potential reservoir of endemic fauna whose value science can barely estimate.
【6】Yet the very isolation that produced this diversity has left it dangerously exposed. Deep-sea bottom trawling and seabed mining, both expanding as terrestrial resources grow scarce, could strip these fragile ecosystems bare long before most of their inhabitants have been catalogued, let alone protected.
【7】"Naming a species is not a quick process," one researcher noted, observing that formally describing the 149 organisms may demand years of painstaking study. That lag, the team insists, is precisely what makes protection urgent rather than optional — a race between the slow pace of taxonomy and the accelerating machinery of extraction.
【8】The findings, published across a series of papers, form part of a broader global campaign to catalogue marine biodiversity before it vanishes. Scientists estimate that as many as two million marine species may exist, the great majority of which remain undescribed; by some accounts, a species can disappear before it is ever collected.
【9】For the public, the message is at once humbling and hopeful. That a single voyage can surface so much unknown life suggests the ocean, though under mounting pressure, still holds wonders capable of inspiring the next generation of explorers and conservationists alike — provided that we choose to know these places before we choose to use them.

四、全文大意
深海覆盖了地球超过三分之二的表面，却几乎未被测绘，科学家常把洋底比作外星世界。由澳大利亚顶尖研究机构海洋生物学家率领的一次考察，把目标锁定在圣诞岛与科科斯（基林）群岛附近、远离任何大陆架的一连串海底山——这些从东印度洋深海平原耸立数千米的古老火山，是荒芜深海中一座座"生命孤岛"。团队借助遥控潜水器和诱饵相机下潜 4000 多米，从从未被人类扰动过的坡面上采集标本；每份标本一经取回，便进入形态学与基因分析的缓慢流程，这是让无名生物变成有名字物种的唯一途径。考察最终带回 149 个分类学家从未正式描述过的物种，收获遍布"生命之树"：梦参属的海参、青眼鱼科的鱼、附着于其他深海动物的寄生生物，以及数十种珊瑚、海绵和蠕虫。这些海底山在数百万年的隔绝中，让无数谱系分化成别处找不到的形态，成为价值难以估量的特有动物群宝库。然而，正是这种隔绝让它们格外脆弱——随着陆地资源日益稀缺，底拖网捕捞和海底采矿不断扩张，可能在大多数"居民"被编目之前，就将这些脆弱生态剥光。研究团队指出，为物种正式命名往往需要多年的艰苦研究，而分类学的缓慢步伐正与不断加速的开采机器赛跑，这使保护成为紧迫之举。这项发现是全球海洋生物编目行动的一部分——科学家估计海洋中可能有多达 200 万种生物，绝大多数仍未被描述，有些物种甚至在被采集之前就已消失。对普通人而言，这一发现既令人谦卑又充满希望：一次航行就能揭示如此之多的未知，说明海洋虽承受日益增长的压力，仍蕴藏着足以激励新一代探索者与保护者的奇迹——前提是我们在"利用"这些地方之前，先选择"认识"它们。
五、思考与仿写
思考题：结合第 5、6 段，为什么海底山的"隔绝"既造就了物种的独特多样，又令它们格外脆弱？结合第 9 段"先认识、后利用"，谈谈你对深海开发与保护之间关系的看法。
仿写题：仿照第 9 段 "That a single voyage can surface so much unknown life suggests the ocean ... still holds wonders ..."（That 引导主语从句 + suggests + that 宾语从句）的句式，围绕「保护环境」「坚持学习」或「绿色生活」写一个句子。
