Lens of Time: Secrets of Schooling | bioGraphic

Shimmering schools of fish have dazzled scientists for centuries with their synchronized maneuvers. Now, high-speed video is revealing how—and why—they do it.

Collective behavior is embodied in swarms of insects, flocks of birds, herds of antelope, and schools of fish. In each of these cases, individuals move through their environment and respond to threats and opportunities almost simultaneously, forming an undulating enclave that seems to operate as a single entity. Such coordinated movement requires the rapid and efficient transfer of information among individuals, but understanding exactly how this information spreads through the group has long eluded scientists. Studying this behavior in schools of fish has been incredibly challenging, because the cues that drive it occur at lightening speed, come from multiple directions and sources, and of course because all of it takes place underwater. Now, Iain Couzin and his colleagues at the Max Planck Institute for Ornithology at the University of Konstanz, Germany are using new observation techniques and technologies—including high-speed video, motion-tracking software, and advanced statistical modeling—to reveal the mysterious mechanics of schooling fish. Their findings may shed light on the evolution and benefits of collective behavior across the animal kingdom.

I’ve wondered this for a long time, and it’s so neat to finally understand a little about it, and humbling to see we still don’t quite know how these fish move so harmoniously.

What's the ap bio answers please😢😢

재귀적 구조가 반복되는 걸 보면 인간을 지켜보는 존재도 인간을 통해 인간의 동기화 현상을 연구 중 일거 같음.

You're right about centralised coordination of information. It's eroding our individual intelligence.

[DrunknCoder]

Great video for understanding swarming

[aeophylus]

There is not yet a good explanation of how so many fish instantaneously reacts to another's movement. What causes the group of fish to turn right or left or retreat. Dependence on nerve conduction travelling from eyes to brain then back to muscle is not possible as nerve conduction speed is too slow- please explain!

This is one of my favourite topics. May I embed this video in a blog post I'm writing? Emergence is an absolutely fascinating phenomenon.

Very interesting hypotheses and stellar photography continue to clutch my attention and interest in your work. Bravo!
Btw I'm always amazed that research scientist pursue and investigate complex and puzzling topics whose secrets of origin can only come from natures grand architect. It's structure relies on Gods obvious supperior and sensitive intelligence. Mother nature after all is his best friend and where would she be without his exquisite interconnected genius of balance? Things that 'seem' to make no sense initially to us make total sense to God. It just takes a few centuries for us to catch up to the overwhelming reality of it's importance.

pretty sure your bait title didn't pay off anywhere in the 8 minutes 41. Where 👏 is 👏the 👏slow 👏motion 👏?

[chrisjones]

are they faster than the speed of light? or do they follow sight/movement?

[Vaijykone]

It's not collective behaviour, it's decentralised and heavily networked behaviour.

Trying to figure out if Jesus fed fish something in the water beforehand to attract so many of them or if it was just "magic".

2:10 I thought they was following a laser pointer

Great stuff. Now can you figure out how to stop forest fires and such???

Many thanks for this beautiful video, which I believe may be inspiring for the audience much broroader than the people interested in animal behaviour. Surprisingly perhaps, I believe these studies will prove illuminating for physiologists and molecular biologists too. Even the title of your video sounds like a pun. There is a widespread and misleading representation in modern biology of DNA as a blueprint of an organism. A blueprint is a general view of a complex structure and to my knowledge there is nothing like it in any genome.
What genomes describe are rules of conduct of individual cells. Cells are too stupid to know they build a lung or a liver or a man. They just care about themselves and sometimes their neighbour. They behave automatically like the sheep or birds in the flocks you showed. Individual animals have no idea of geometry or predator psychology, still they form those impressive dynamic structures. I suppose the behaviour of individual cells in plant or animal bodies resembles the behaviour of individual sheep or birds in a flock. The cells read simple cheatsheets, not the service manuals.
