深海琵琶鱼的第一个交配镜头

First footage of deep-sea anglerfish pair

这是深海琵琶鱼的交配
This is a deep-sea anglerfish mating pair.
这些动物生存在海平面下百米到千米之间
These animals have rarely been observed in their natural habitat
因此 极少被观测到
-hundreds to thousands of meters below the ocean’s surface.
本视频记录了极为罕见的镜头
You’re watching one of the few known videos.
视频第一次展示了
And this one shows a sexually parasitic pair
深海动物的性交过程
for the first time.
这意味着整个交配过程中 弱小的雄性一直连接在雌性身上
That means during mating, the tiny male is permanently attached to the female.
他获取营养素 她得到精子
He gets nutrients and she gets sperm.
这些特殊的鱼类很难在海平面存活
These specialized fish rarely survive the journey to the surface.
在此之前 深海琵琶鱼的研究
Before now, most deep sea anglerfish studies
最多就是用网捕上来的死鱼
used dead animals pulled up in nets
有时还是博物馆里的藏品
and sometimes preserved in museums.
研究团队本次使用专为此设计的潜水设备
In this case, the research team used a special submersible,
拍摄生活在此深度生物的影像
designed to capture images of creatures that live at these great depths.
像鮟鱇目的其他鱼类一样
Like most other members of its order,
琵琶鱼以嘴前端漂浮的
this anglerfish is known for the bioluminescent,
“小灯笼”引猎物上钩
lure-like appendage that drifts in front of its mouth
而闻名
to attract prey.
但这是第一次证明
But this is the first time that what may be bioluminescence
“小灯笼”发光的原理
on the fish’s filaments has been documented.
琵琶鱼的“小灯笼”
The swaying swarm of thin projections around the angler
像是3d版的猫咪胡须
may act like a 3-d array of cat whiskers
感知危险 诱捕猎物
-sensing dangers and prey in the environment.
在如此深的大海中
There’s little to eat at this depth
食物短缺 环境冰冷
and it is very cold,
留给琵琶鱼的卡路里很少很少
leaving anglerfish with few calories to spare
所以视频中的画面就很合理了
so it makes sense that as this video shows,
雌鱼看起来几乎不消耗能量
the anglerfish female seems to use very little energy
只是在水中慢慢漂浮 翻滚
slowly drifting and rolling through the water.
但是我们不太了解他们的新陈代谢
But we don’t know much about their metabolism,
微生物怎么为他们提供能量
the bacteria that supply their glow,
雌鱼为什么不排斥雄鱼的身体
or how the female’s body doesn’t reject the male’s.
这艘特别的潜艇从2013年就开始
The special ship that took this video has
拍摄视频
been in operation since 2013
世界上几乎没有这样的设备
and there aren’t many like it in the world.
所以 还有许多琵琶鱼的秘密可能
So chances are, many anglerfish mysteries will stay that way
在等待着我们的发现
for some time to come.
