The Dumbest Animal Alive · Kurzgesagt – In a Nutshell
介绍海洋太阳鱼（Mola）的奇特特征和生存方式，适合练习描述生物特征和表达观点。
The Sunfish, or Mola, is the dumbest creature alive.
太阳鱼（学名：Mola）堪称现存最“愚蠢”的生物。
Not just from an intelligence perspective – I mean, look at it!
这不仅仅是从情报角度来看的；我的意思是，你们看看吧！
It's a being of extremes and comically bad at being an animal.
它是一种极端化的生物，在“扮演动物”这一方面表现得极其糟糕（甚至可以说是滑稽可笑）。
Its evolutionary strategy is to be chunky boys, weaker than their predators, staring into the ocean with empty dumb eyes,
它的进化策略就是：体型粗壮、比天敌更弱小，用空洞无神的眼神凝视着大海。
eating the least nutritious food possible but growing amazingly fast, getting infested by parasites and dying horribly.
它们吃的是营养价值最低的食物，却能以惊人的速度生长；随后会被寄生虫侵袭，最终痛苦地死去。
If you presented the sunfish in animal invention class everybody would be really upset with you.
如果你在“动物发明”课上展示太阳鱼（这种生物），所有人都会对你非常不满的。
And yet somehow the Mola doesn't just survives but thrives.
然而，这种名为“Mola”的生物不仅成功存活了下来，甚至还繁衍生息。
How?
怎么做到的？
Like actually how?
到底是怎么做到的呢？
Are you ok Evolution?
Evolution”，你还好吗？
The genus of Mola is a fish built wrong, a giant head that evolution lost interest in half way through.
Mola属的鱼类属于“构造异常”的鱼类：它们的头部异常巨大，而进化过程似乎在发育到这一阶段时突然“失去了继续完善这些结构的兴趣”（即进化进程在此处中断了）。
Its body is very flat and circular without a real tail, instead it has a sort of rudder-like stump.
它的身体非常扁平且呈圆形，没有真正的尾巴；取而代之的是一个类似舵状的突起结构。
Two fins on the top and bottom give it an ...
顶部和底部各有一个鳍状结构，这使得它具有……（此处“……”应结合具体语境补充完整）。
uhm ...
嗯……
unorthodox swimming style.
非传统的游泳方式。
They propel themselves forward by flapping their fins in a goofy wobbling motion with as little grace as possible.
它们通过摆动鳍部来推动自己前进，动作显得笨拙而摇晃，毫无优雅可言。
It’s less like swimming and more like underwater flying – although when they really try, Mola can match strong swimmers like salmon or marlins.
这种运动与其说像游泳，不如说更像在水下飞行；不过当它们真正全力以赴时，Mola（一种海洋鱼类）的游速完全可以与鲑鱼或马林鱼等游泳能力很强的鱼类相媲美。
Sunfish also don’t have a swim bladder, the gas-filled organ most fish use for buoyancy.
太阳鱼也没有鱼鳔——那种充满气体的器官，大多数鱼类依靠它来保持浮力。
Instead they have a jelly-like layer of flesh that is 90% water to dive or surface, which definitely doesn’t help with agility.
实际上，它们体内有一层类似果冻的肉质组织，其中90%的成分是水；这种组织主要用于让它们潜入水中或浮出水面。显然，这种结构对它们的机动性（即移动的灵活性）没有任何帮助。
Most of the time Mola cruises around leisurely.
大多数时候，Mola（一种海洋生物）都会悠闲地游来游去。
Their teeth are fused into a parrot-like beak that sits in a tiny gaping pout that's open most of the time.
它们的牙齿融合在一起，形成了类似鹦鹉的喙状结构；这个喙状结构位于一张始终微微张开的、形状极小的嘴巴中。
Together with two huge empty eyes, the sunfish has a perpetual derpy face, always looking stunned.
除了那两只空洞的大眼睛外，太阳鱼的脸总是显得呆呆的、傻傻的，仿佛永远都处于震惊的状态。
Sunfish don’t have proper scales but some of the thickest skin in the ocean after whales.
太阳鱼并没有真正的鳞片，但它们的皮肤厚度在海洋生物中属于最厚的之一（仅次于鲸鱼）。
Up to 15 cm thick, it's rough and rubbery and often covered in mucus, like armour made from car tyres.
这种物质的厚度可达15厘米，表面粗糙且具有弹性，通常覆盖着黏液，就像是用汽车轮胎制成的“盔甲”一样。
Although most of what it is protecting is not that great in the first place.
尽管它所保护的东西本身大多并不那么出色（或者说并没有什么特别的价值）。
Sunfish can become as big and massive as a large car but its organs are collected together in the front of their body,
太阳鱼可以长得像一辆大型汽车一样庞大，不过它们的内脏都集中在身体的前方。
while most of their bulk is oddly textured, flabby, gelatinous tissue – an animal made from all the worst parts of a steak.
虽然它们的大部分身体结构由质地粗糙、松软且呈胶状的组织构成（这种组织仿佛是由牛排中最“劣质”的部分组合而成的），但它们仍然属于动物范畴。
This very mid meat is supported by a sort of weird skeleton without ribs or a tailbone and a lot of cartilage.
这块位于肉中部的组织，实际上是由一种结构奇特的“骨架”支撑着的；这种“骨架”没有肋骨或尾骨，且含有大量的软骨。
Their weird bodies are a mobile mini ecosystem, infested and saturated with around 50 species of parasites – probably more than any other fish.
它们奇特的体型实际上构成了一个“移动式的微型生态系统”：体内寄生着大约50种寄生虫，这一数量可能超过了任何其他鱼类。
Crustaceans, barnacles, various worms and protozoans live on and in their skin, muscles, gills or organs.
甲壳类动物、藤壶、多种蠕虫以及原生动物都寄生于它们的皮肤、肌肉、鳃或内脏器官中。
They are such a paradise for parasites that even their parasites have their own smaller parasites!
它们简直就是寄生虫的“天堂”；甚至连它们体内的寄生虫，也有自己的更微小的寄生虫！
Some Mola are also followed by an entourage of other fish that seek protection, food scraps or feed on their inhabitants.
有些翻车鱼的身边还会跟着一群其他鱼类；这些鱼类要么寻求保护，要么捡食鱼身上的残渣，要么以翻车鱼体内的生物为食。
This awkward situation may be the root of their most bizarre behavior: Mola frequently swim to the surface to float on their side like a pancake.
这种尴尬的局面或许正是他们那些最奇怪行为的根源：Mola（一种海洋生物）经常会游到水面，然后侧躺在那里，就像一块煎饼一样。
They are sunbathing to warm up again from deep cold dives – which is where they got their name from.
它们正在晒太阳，以便从寒冷的水中重新暖和起来；它们的名字也正是由此而来。
But they also do it to present their body to seabirds like albatrosses.
但他们这样做也是为了向信天翁之类的海鸟展示自己的身体。
The birds start picking the parasites from
这些鸟开始从……身上啄取寄生虫。
the Sunfish body – while smaller fish that live near the surface take care of the bottom half – cleaning them in exchange for a snack.
太阳鱼的“身体结构”是这样的：那些生活在水面附近的较小鱼类会负责清理太阳鱼身体下半部分，作为回报，它们可以获取一些食物（即小零食）。
While this is a great adaptation to their parasite infection it sadly often leads to dead sunfish when they collide with boats.
虽然这种适应机制对于它们抵御寄生虫感染非常有效，但遗憾的是，当太阳鱼与船只发生碰撞时，它们往往会因此死亡。
Since they are still cold and slow from the deep when they float on the surface, they can't react to anything coming at them.
由于它们从深海浮到水面时仍处于低温状态，行动也变得迟缓，因此无法对任何来袭的物体做出反应。
Once Mola reach a certain size most
一旦莫拉（Mola）鱼达到一定体型，大多数……
